About

Plugins

Plugins are chat extensions designed specifically for language models like ChatGPT, enabling them to access up-to-date information, run computations, or interact with third-party services in response to a user's request. They unlock a wide range of potential use cases and enhance the capabilities of language models.

Developers can create a plugin by exposing an API through their website and providing a standardized manifest file that describes the API. ChatGPT consumes these files and allows the AI models to make calls to the API defined by the developer.

A plugin consists of:

An API
An API schema (OpenAPI JSON or YAML format)
A manifest (JSON file) that defines relevant metadata for the plugin

The Retrieval Plugin already contains all of these components. Read the Chat Plugins blogpost here, and find the docs here.

Retrieval Plugin

This is a plugin for ChatGPT that enables semantic search and retrieval of personal or organizational documents. It allows users to obtain the most relevant document snippets from their data sources, such as files, notes, or emails, by asking questions or expressing needs in natural language. Enterprises can make their internal documents available to their employees through ChatGPT using this plugin.

The plugin uses OpenAI's text-embedding-ada-002 embeddings model to generate embeddings of document chunks, and then stores and queries them using a vector database on the backend. As an open-source and self-hosted solution, developers can deploy their own Retrieval Plugin and register it with ChatGPT. The Retrieval Plugin supports several vector database providers, allowing developers to choose their preferred one from a list.

A FastAPI server exposes the plugin's endpoints for upserting, querying, and deleting documents. Users can refine their search results by using metadata filters by source, date, author, or other criteria. The plugin can be hosted on any cloud platform that supports Docker containers, such as Fly.io, Heroku or Azure Container Apps. To keep the vector database updated with the latest documents, the plugin can process and store documents from various data sources continuously, using incoming webhooks to the upsert and delete endpoints. Tools like Zapier or Make can help configure the webhooks based on events or schedules.

Memory Feature

A notable feature of the Retrieval Plugin is its capacity to provide ChatGPT with memory. By utilizing the plugin's upsert endpoint, ChatGPT can save snippets from the conversation to the vector database for later reference (only when prompted to do so by the user). This functionality contributes to a more context-aware chat experience by allowing ChatGPT to remember and retrieve information from previous conversations. Learn how to configure the Retrieval Plugin with memory here.

Security

The Retrieval Plugin allows ChatGPT to search a vector database of content, and then add the best results into the ChatGPT session. This means it doesn’t have any external effects, and the main risk consideration is data authorization and privacy. Developers should only add content into their Retrieval Plugin that they have authorization for and that they are fine with appearing in users’ ChatGPT sessions. You can choose from a number of different authentication methods to secure the plugin (more information here).

API Endpoints

The Retrieval Plugin is built using FastAPI, a web framework for building APIs with Python. FastAPI allows for easy development, validation, and documentation of API endpoints. Find the FastAPI documentation here.

One of the benefits of using FastAPI is the automatic generation of interactive API documentation with Swagger UI. When the API is running locally, Swagger UI at <local_host_url i.e. http://0.0.0.0:8000>/docs can be used to interact with the API endpoints, test their functionality, and view the expected request and response models.

The plugin exposes the following endpoints for upserting, querying, and deleting documents from the vector database. All requests and responses are in JSON format, and require a valid bearer token as an authorization header.

/upsert: This endpoint allows uploading one or more documents and storing their text and metadata in the vector database. The documents are split into chunks of around 200 tokens, each with a unique ID. The endpoint expects a list of documents in the request body, each with a text field, and optional id and metadata fields. The metadata field can contain the following optional subfields: source, source_id, url, created_at, and author. The endpoint returns a list of the IDs of the inserted documents (an ID is generated if not initially provided).
/upsert-file: This endpoint allows uploading a single file (PDF, TXT, DOCX, PPTX, or MD) and storing its text and metadata in the vector database. The file is converted to plain text and split into chunks of around 200 tokens, each with a unique ID. The endpoint returns a list containing the generated id of the inserted file.
/query: This endpoint allows querying the vector database using one or more natural language queries and optional metadata filters. The endpoint expects a list of queries in the request body, each with a query and optional filter and top_k fields. The filter field should contain a subset of the following subfields: source, source_id, document_id, url, created_at, and author. The top_k field specifies how many results to return for a given query, and the default value is 3. The endpoint returns a list of objects that each contain a list of the most relevant document chunks for the given query, along with their text, metadata and similarity scores.
/delete: This endpoint allows deleting one or more documents from the vector database using their IDs, a metadata filter, or a delete_all flag. The endpoint expects at least one of the following parameters in the request body: ids, filter, or delete_all. The ids parameter should be a list of document IDs to delete; all document chunks for the document with these IDS will be deleted. The filter parameter should contain a subset of the following subfields: source, source_id, document_id, url, created_at, and author. The delete_all parameter should be a boolean indicating whether to delete all documents from the vector database. The endpoint returns a boolean indicating whether the deletion was successful.

The detailed specifications and examples of the request and response models can be found by running the app locally and navigating to http://0.0.0.0:8000/openapi.json, or in the OpenAPI schema here. Note that the OpenAPI schema only contains the /query endpoint, because that is the only function that ChatGPT needs to access. This way, ChatGPT can use the plugin only to retrieve relevant documents based on natural language queries or needs. However, if developers want to also give ChatGPT the ability to remember things for later, they can use the /upsert endpoint to save snippets from the conversation to the vector database. An example of a manifest and OpenAPI schema that gives ChatGPT access to the /upsert endpoint can be found here.

To include custom metadata fields, edit the DocumentMetadata and DocumentMetadataFilter data models here, and update the OpenAPI schema here. You can update this easily by running the app locally, copying the JSON found at http://0.0.0.0:8000/sub/openapi.json, and converting it to YAML format with Swagger Editor. Alternatively, you can replace the openapi.yaml file with an openapi.json file.

General Environment Variables

The API requires the following environment variables to work:

Name	Required	Description
`DATASTORE`	Yes	This specifies the vector database provider you want to use to store and query embeddings. You can choose from `pinecone`, `weaviate`, `zilliz`, `milvus`, `qdrant`, or `redis`.
`BEARER_TOKEN`	Yes	This is a secret token that you need to authenticate your requests to the API. You can generate one using any tool or method you prefer, such as jwt.io.
`OPENAI_API_KEY`	Yes	This is your OpenAI API key that you need to generate embeddings using the `text-embedding-ada-002` model. You can get an API key by creating an account on OpenAI.

Choosing a Vector Database

The plugin supports several vector database providers, each with different features, performance, and pricing. Depending on which one you choose, you will need to use a different Dockerfile and set different environment variables. The following sections provide detailed information and instructions on using each vector database provider.

Pinecone

Pinecone is a managed vector database built for speed, scale, and shipping to production sooner. To use Pinecone as your vector database provider, first get an API key by signing up for an account. You can access your API key from the "API Keys" section in the sidebar of your dashboard. Pinecone also supports hybrid search and at the time of writing is the only datastore to support SPLADE sparse vectors natively.

A full Jupyter notebook walkthrough for the Pinecone flavor of the retrieval plugin can be found here. There is also a video walkthrough here.

The app will create a Pinecone index for you automatically when you run it for the first time. Just pick a name for your index and set it as an environment variable.

Environment Variables:

Name	Required	Description
`DATASTORE`	Yes	Datastore name, set this to `pinecone`
`BEARER_TOKEN`	Yes	Your secret token for authenticating requests to the API
`OPENAI_API_KEY`	Yes	Your OpenAI API key for generating embeddings with the `text-embedding-ada-002` model
`PINECONE_API_KEY`	Yes	Your Pinecone API key, found in the Pinecone console
`PINECONE_ENVIRONMENT`	Yes	Your Pinecone environment, found in the Pinecone console, e.g. `us-west1-gcp`, `us-east-1-aws`, etc.
`PINECONE_INDEX`	Yes	Your chosen Pinecone index name. Note: Index name must consist of lower case alphanumeric characters or '-'

If you want to create your own index with custom configurations, you can do so using the Pinecone SDK, API, or web interface (see docs). Make sure to use a dimensionality of 1536 for the embeddings and avoid indexing on the text field in the metadata, as this will reduce the performance significantly.

# Creating index with Pinecone SDK - use only if you wish to create the index manually.

import os, pinecone

pinecone.init(api_key=os.environ['PINECONE_API_KEY'],
              environment=os.environ['PINECONE_ENVIRONMENT'])

pinecone.create_index(name=os.environ['PINECONE_INDEX'],
                      dimension=1536,
                      metric='cosine',
                      metadata_config={
                          "indexed": ['source', 'source_id', 'url', 'created_at', 'author', 'document_id']})

Weaviate

Set up a Weaviate Instance

Weaviate is an open-source vector search engine designed to scale seamlessly into billions of data objects. This implementation supports hybrid search out-of-the-box (meaning it will perform better for keyword searches).

You can run Weaviate in 4 ways:

SaaS – with Weaviate Cloud Services (WCS).

WCS is a fully managed service that takes care of hosting, scaling, and updating your Weaviate instance. You can try it out for free with a sandbox that lasts for 30 days.

To set up a SaaS Weaviate instance with WCS:
1. Navigate to Weaviate Cloud Console.
2. Register or sign in to your WCS account.
3. Create a new cluster with the following settings:
  - Name – a unique name for your cluster. The name will become part of the URL used to access this instance.
  - Subscription Tier – Sandbox for a free trial, or contact [email protected] for other options.
  - Weaviate Version - The latest version by default.
  - OIDC Authentication – Enabled by default. This requires a username and password to access your instance.
4. Wait for a few minutes until your cluster is ready. You will see a green tick ✔️ when it's done. Copy your cluster URL.
Hybrid SaaS

If you need to keep your data on-premise for security or compliance reasons, Weaviate also offers a Hybrid SaaS option: Weaviate runs within your cloud instances, but the cluster is managed remotely by Weaviate. This gives you the benefits of a managed service without sending data to an external party.

The Weaviate Hybrid SaaS is a custom solution. If you are interested in this option, please reach out to [email protected].
Self-hosted – with a Docker container

To set up a Weaviate instance with Docker:
1. Install Docker on your local machine if it is not already installed.
2. Install the Docker Compose Plugin
3. Download a docker-compose.yml file with this curl command:
```
curl -o docker-compose.yml "https://configuration.weaviate.io/v2/docker-compose/docker-compose.yml?modules=standalone&runtime=docker-compose&weaviate_version=v1.18.0"
```
  Alternatively, you can use Weaviate's docker compose configuration tool to generate your own docker-compose.yml file.
4. Run docker compose up -d to spin up a Weaviate instance.
  
  To shut it down, run docker compose down.
Self-hosted – with a Kubernetes cluster

To configure a self-hosted instance with Kubernetes, follow Weaviate's documentation.

Configure Weaviate Environment Variables

You need to set some environment variables to connect to your Weaviate instance.

Retrieval App Environment Variables

Name	Required	Description
`DATASTORE`	Yes	Datastore name. Set this to `weaviate`
`BEARER_TOKEN`	Yes	Your secret token
`OPENAI_API_KEY`	Yes	Your OpenAI API key

Weaviate Datastore Environment Variables

Name	Required	Description	Default
`WEAVIATE_HOST`	Optional	Your Weaviate instance host address (see notes below)	`http://127.0.0.1`
`WEAVIATE_PORT`	Optional	Your Weaviate port number	8080
`WEAVIATE_INDEX`	Optional	Your chosen Weaviate class/collection name to store your documents	OpenAIDocument

For WCS instances, set WEAVIATE_PORT to 443 and WEAVIATE_HOST to https://(wcs-instance-name).weaviate.network. For example: https://my-project.weaviate.network/.

For self-hosted instances, if your instance is not at 127.0.0.1:8080, set WEAVIATE_HOST and WEAVIATE_PORT accordingly. For example: WEAVIATE_HOST=http://localhost/ and WEAVIATE_PORT=4040.

Weaviate Auth Environment Variables

If you enabled OIDC authentication for your Weaviate instance (recommended for WCS instances), set the following environment variables. If you enabled anonymous access, skip this section.

Name	Required	Description
`WEAVIATE_USERNAME`	Yes	Your OIDC or WCS username
`WEAVIATE_PASSWORD`	Yes	Your OIDC or WCS password
`WEAVIATE_SCOPES`	Optional	Space-separated list of scopes

Learn more about authentication in Weaviate and the Python client authentication.

Weaviate Batch Import Environment Variables

Weaviate uses a batching mechanism to perform operations in bulk. This makes importing and updating your data faster and more efficient. You can adjust the batch settings with these optional environment variables:

Name	Required	Description	Default
`WEAVIATE_BATCH_SIZE`	Optional	Number of insert/updates per batch operation	20
`WEAVIATE_BATCH_DYNAMIC`	Optional	Lets the batch process decide the batch size	False
`WEAVIATE_BATCH_TIMEOUT_RETRIES`	Optional	Number of retry-on-timeout attempts	3
`WEAVIATE_BATCH_NUM_WORKERS`	Optional	The max number of concurrent threads to run batch operations	1

Note: The optimal WEAVIATE_BATCH_SIZE depends on the available resources (RAM, CPU). A higher value means faster bulk operations, but also higher demand for RAM and CPU. If you experience failures during the import process, reduce the batch size.

Setting WEAVIATE_BATCH_SIZE to None means no limit to the batch size. All insert or update operations would be sent to Weaviate in a single operation. This might be risky, as you lose control over the batch size.

Learn more about batch configuration in Weaviate.

Self-hosted Qdrant Instance

For a self-hosted version, use Docker containers or the official Helm chart for deployment. The only required parameter is the QDRANT_URL that points to the Qdrant server URL.

Example:

QDRANT_URL="http://YOUR_HOST.example.com:6333"

The other parameters are optional and can be changed if needed.

Running Qdrant Integration Tests

A suite of integration tests verifies the Qdrant integration. To run it, start a local Qdrant instance in a Docker container.

docker run -p "6333:6333" -p "6334:6334" qdrant/qdrant:v1.0.3

Then, launch the test suite with this command:

pytest ./tests/datastore/providers/qdrant/test_qdrant_datastore.py

Redis

Redis is a real-time data platform that supports a variety of use cases for everyday applications as well as AI/ML workloads. Use Redis as a low-latency vector engine by creating a Redis database with the Redis Stack docker container. For a hosted/managed solution, try Redis Cloud. See more helpful examples of Redis as a vector database here.

The database needs the RediSearch module (>=v2.6) and RedisJSON, which are included in the self-hosted docker compose above.
Run the App with the Redis docker image: docker compose up -d in this dir.
The app automatically creates a Redis vector search index on the first run. Optionally, create a custom index with a specific name and set it as an environment variable (see below).
To enable more hybrid searching capabilities, adjust the document schema here.

Environment Variables:

Name	Required	Description	Default
`DATASTORE`	Yes	Datastore name, set to `redis`
`BEARER_TOKEN`	Yes	Secret token

`REDIS_DOC_PREFIX`	Optional	Redis key prefix for the index	`doc`
`REDIS_DISTANCE_METRIC`	Optional	Vector similarity distance metric	`COSINE`
`REDIS_INDEX_TYPE`	Optional	Vector index algorithm type	`FLAT`

Running the API locally

To run the API locally, you first need to set the requisite environment variables with the export command:

export DATASTORE=<your_datastore>
export BEARER_TOKEN=<your_bearer_token>
export OPENAI_API_KEY=<your_openai_api_key>
<Add the environment variables for your chosen vector DB here>

Start the API with:

poetry run start

Append docs to the URL shown in the terminal and open it in a browser to access the API documentation and try out the endpoints (i.e. http://0.0.0.0:8000/docs). Make sure to enter your bearer token and test the API endpoints.

Note: If you add new dependencies to the pyproject.toml file, you need to run poetry lock and poetry install to update the lock file and install the new dependencies.

Personalization

You can personalize the Retrieval Plugin for your own use case by doing the following:

Replace the logo: Replace the image in logo.png with your own logo.
Edit the data models: Edit the DocumentMetadata and DocumentMetadataFilter data models in models.py to add custom metadata fields. Update the OpenAPI schema in openapi.yaml accordingly. To update the OpenAPI schema more easily, you can run the app locally, then navigate to http://0.0.0.0:8000/sub/openapi.json and copy the contents of the webpage. Then go to Swagger Editor and paste in the JSON to convert it to a YAML format. You could also replace the openapi.yaml file with an openapi.json file in the .well-known folder.
Change the plugin name, description, and usage instructions: Update the plugin name, user-facing description, and usage instructions for the model. You can either edit the descriptions in the main.py file or update the openapi.yaml file. Follow the same instructions as in the previous step to update the OpenAPI schema.
Enable ChatGPT to save information from conversations: See the instructions in the memory example folder.

Authentication Methods

You can choose from four options for authenticating requests to your plugin:

No Authentication: Anyone can add your plugin and use its API without any credentials. This option is suitable if you are only exposing documents that are not sensitive or already public. It provides no security for your data. If using this method, copy the contents of this main.py into the actual main.py file. Example manifest here.
HTTP Bearer: You can use a secret token as a header to authorize requests to your plugin. There are two variants of this option:
- User Level (default for this implementation): Each user who adds your plugin to ChatGPT must provide the bearer token when adding the plugin. You can generate and distribute these tokens using any tool or method you prefer, such as jwt.io. This method provides better security as each user has to enter the shared access token. If you require a unique access token for each user, you will need to implement this yourself in the main.py file. Example manifest here.
- Service Level: Anyone can add your plugin and use its API without credentials, but you must add a bearer token when registering the plugin. When you install your plugin, you need to add your bearer token, and will then receive a token from ChatGPT that you must include in your hosted manifest file. Your token will be used by ChatGPT to authorize requests to your plugin on behalf of all users who add it. This method is more convenient for users, but it may be less secure as all users share the same token and do not need to add a token to install the plugin. Example manifest here.
OAuth: Users must go through an OAuth flow to add your plugin. You can use an OAuth provider to authenticate users who add your plugin and grant them access to your API. This method offers the highest level of security and control, as users authenticate through a trusted third-party provider. However, you will need to implement the OAuth flow yourself in the main.py file and provide the necessary parameters in your manifest file. Example manifest here.

Consider the benefits and drawbacks of each authentication method before choosing the one that best suits your use case and security requirements. If you choose to use a method different to the default (User Level HTTP), make sure to update the manifest file here.

Deployment

You can deploy your app to different cloud providers, depending on your preferences and requirements. However, regardless of the provider you choose, you will need to update two files in your app: openapi.yaml and ai-plugin.json. As outlined above, these files define the API specification and the AI plugin configuration for your app, respectively. You need to change the url field in both files to match the address of your deployed app.

Before deploying your app, you might want to remove unused dependencies from your pyproject.toml file to reduce the size of your app and improve its performance. Depending on the vector database provider you choose, you can remove the packages that are not needed for your specific provider.

Here are the packages you can remove for each vector database provider:

Pinecone: Remove weaviate-client, pymilvus, qdrant-client, and redis.
Weaviate: Remove pinecone-client, pymilvus, qdrant-client, and redis.
Zilliz: Remove pinecone-client, weaviate-client, qdrant-client, and redis.
Milvus: Remove pinecone-client, weaviate-client, qdrant-client, and redis.
Qdrant: Remove pinecone-client, weaviate-client, pymilvus, and redis.
Redis: Remove pinecone-client, weaviate-client, pymilvus, and qdrant-client.

After removing the unnecessary packages from the pyproject.toml file, you don't need to run poetry lock and poetry install manually. The provided Dockerfile takes care of installing the required dependencies using the requirements.txt file generated by the poetry export command.

Once you have deployed your app, consider uploading an initial batch of documents using one of these scripts or by calling the /upsert endpoint, for example:

curl -X POST https://your-app-url.com/upsert \
  -H "Authorization: Bearer <your_bearer_token>" \
  -H "Content-type: application/json" \
  -d '{"documents": [{"id": "doc1", "text": "Hello world", "metadata": {"source_id": "12345", "source": "file"}}, {"text": "How are you?", "metadata": {"source_id": "23456"}}]}'

<Add the environment variables for your chosen vector DB here>

Alternatively, you could set environment variables in the Fly.io Console.

At this point, you can change the plugin url in your plugin manifest file here, and in your OpenAPI schema here to the url for your Fly.io app, which will be https://your-app-name.fly.dev.

Deploy your app with:

flyctl deploy

After completing these steps, your Docker container should be deployed to Fly.io and running with the necessary environment variables set. You can view your app by running:

flyctl open

which will open your app url. You should be able to find the OpenAPI schema at <your_app_url>/.well-known/openapi.yaml and the manifest at <your_app_url>/.well-known/ai-plugin.json.

To view your app logs:

flyctl logs

Now, make sure you have changed the plugin url in your plugin manifest file here, and in your OpenAPI schema here, and redeploy with flyctl deploy. This url will be https://<your-app-name>.fly.dev.

Debugging tips: Fly.io uses port 8080 by default.

If your app fails to deploy, check if the environment variables are set correctly, and then check if your port is configured correctly. You could also try using the -e flag with the flyctl launch command to set the environment variables at launch.

Deploying to Heroku

To deploy the Docker container from this repository to Heroku and set the required environment variables, follow these steps:

Install Docker on your local machine if it is not already installed.

Install the Heroku CLI on your local machine.

Clone the repository from GitHub:

git clone https://github.com/openai/chatgpt-retrieval-plugin.git

Navigate to the cloned repository directory:

cd path/to/chatgpt-retrieval-plugin

Log in to the Heroku CLI:

heroku login

Create a Heroku app:

heroku create [app-name]

Log in to the Heroku Container Registry:

heroku container:login

Alternatively, you can use a command from the Makefile to log in to the Heroku Container Registry by running:

make heroku-login

Build the Docker image using the Dockerfile:

docker buildx build --platform linux/amd64 -t [image-name] .

(Replace [image-name] with the name you want to give your Docker image)

Push the Docker image to the Heroku Container Registry, and release the newly pushed image to your Heroku app.

docker tag [image-name] registry.heroku.com/[app-name]/web
docker push registry.heroku.com/[app-name]/web
heroku container:release web -a [app-name]

Alternatively, you can use a command from the to push the Docker image to the Heroku Container Registry by running:

make heroku-push

Note: You will need to edit the Makefile and replace <your app name> with your actual app name.

Set the required environment variables for your Heroku app:

heroku config:set DATASTORE=your_datastore \
OPENAI_API_KEY=your_openai_api_key \
BEARER_TOKEN=your_bearer_token \
<Add the environment variables for your chosen vector DB here> \
-a [app-name]

You could also set environment variables in the Heroku Console.

After completing these steps, your Docker container should be deployed to Heroku and running with the necessary environment variables set. You can view your app by running:

heroku open -a [app-name]

which will open your app url. You should be able to find the OpenAPI schema at <your_app_url>/.well-known/openapi.yaml and the manifest at <your_app_url>/.well-known/ai-plugin.json.

To view your app logs:

heroku logs --tail -a [app-name]

Now make sure to change the plugin url in your plugin manifest file here, and in your OpenAPI schema here, and redeploy with make heroku-push. This url will be https://your-app-name.herokuapp.com.

Other Deployment Options

Some possible other options for deploying the app are:

Azure Container Apps: This is a cloud platform that allows you to deploy and manage web apps using Docker containers. You can use the Azure CLI or the Azure Portal to create and configure your app service, and then push your Docker image to a container registry and deploy it to your app service. You can also set environment variables and scale your app using the Azure Portal. Learn more here.
Google Cloud Run: This is a serverless platform that allows you to run stateless web apps using Docker containers. You can use the Google Cloud Console or the gcloud command-line tool to create and deploy your Cloud Run service, and then push your Docker image to the Google Container Registry and deploy it to your service. You can also set environment variables and scale your app using the Google Cloud Console. Learn more here.
AWS Elastic Container Service: This is a cloud platform that allows you to run and manage web apps using Docker containers. You can use the AWS CLI or the AWS Management Console to create and configure your ECS cluster, and then push your Docker image to the Amazon Elastic Container Registry and deploy it to your cluster. You can also set environment variables and scale your app using the AWS Management Console. Learn more here.

After you create your app, make sure to change the plugin url in your plugin manifest file here, and in your OpenAPI schema here, and redeploy.

Installing a Developer Plugin

To install a developer plugin, follow the steps below:

First, create your developer plugin by deploying it to your preferred hosting platform (e.g. Fly.io, Heroku, etc.) and updating the plugin URL in the manifest file and OpenAPI schema.
Go to ChatGPT and select "Plugins" from the model picker.
From the plugins picker, scroll to the bottom and click on "Plugin store."
Go to "Develop your own plugin" and follow the instructions provided. You will need to enter the domain where your plugin is deployed.
Follow the instructions based on the authentication type you have chosen for your plugin (e.g. if your plugin uses Service Level HTTP, you will have to paste in your access token, then paste the new access token you receive from the plugin flow into your ai-plugin.json file and redeploy your app).
Next, you must add your plugin. Go to the "Plugin store" again and click on "Install an unverified plugin."
Follow the instructions provided, which will require you to enter the domain where your plugin is deployed.
Follow the instructions based on the authentication type you have chosen for your plugin (e.g. if your plugin uses User Level HTTP, you will have to paste in your bearer token).

After completing these steps, your developer plugin should be installed and ready to use in ChatGPT.

Webhooks

To keep the documents stored in the vector database up-to-date, consider using tools like Zapier or Make to configure incoming webhooks to your plugin's API based on events or schedules. For example, this could allow you to sync new information as you update your notes or receive emails. You can also use a Zapier Transfer to batch process a collection of existing documents and upload them to the vector database.

If you need to pass custom fields from these tools to your plugin, you might want to create an additional Retrieval Plugin API endpoint that calls the datastore's upsert function, such as upsert-email. This custom endpoint can be designed to accept specific fields from the webhook and process them accordingly.

To set up an incoming webhook, follow these general steps:

Choose a webhook tool like Zapier or Make and create an account.
Set up a new webhook or transfer in the tool, and configure it to trigger based on events or schedules.
Specify the target URL for the webhook, which should be the API endpoint of your retrieval plugin (e.g. https://your-plugin-url.com/upsert).
Configure the webhook payload to include the necessary data fields and format them according to your retrieval plugin's API requirements.
Test the webhook to ensure it's working correctly and sending data to your retrieval plugin as expected.

After setting up the webhook, you may want to run a backfill to ensure that any previously missed data is included in the vector database.

Remember that if you want to use incoming webhooks to continuously sync data, you should consider running a backfill after setting these up to avoid missing any data.

In addition to using tools like Zapier and Make, you can also build your own custom integrations to sync data with your Retrieval Plugin. This allows you to have more control over the data flow and tailor the integration to your specific needs and requirements.

Scripts

The scripts folder contains scripts to batch upsert or process text documents from different data sources, such as a zip file, JSON file, or JSONL file. These scripts use the plugin's upsert utility functions to upload the documents and their metadata to the vector database, after converting them to plain text and splitting them into chunks. Each script folder has a README file that explains how to use it and what parameters it requires. You can also optionally screen the documents for personally identifiable information (PII) using a language model and skip them if detected, with the services.pii_detection module. This can be helpful if you want to avoid uploading sensitive or private documents to the vector database unintentionally. Additionally, you can optionally extract metadata from the document text using a language model, with the services.extract_metadata module. This can be useful if you want to enrich the document metadata. Note: if using incoming webhooks to continuously sync data, consider running a backfill after setting these up to avoid missing any data.

The scripts are:

process_json: This script processes a file dump of documents in a JSON format and stores them in the vector database with some metadata. The format of the JSON file should be a list of JSON objects, where each object represents a document. The JSON object should have a text field and optionally other fields to populate the metadata. You can provide custom metadata as a JSON string and flags to screen for PII and extract metadata.
process_jsonl: This script processes a file dump of documents in a JSONL format and stores them in the vector database with some metadata. The format of the JSONL file should be a newline-delimited JSON file, where each line is a valid JSON object representing a document. The JSON object should have a text field and optionally other fields to populate the metadata. You can provide custom metadata as a JSON string and flags to screen for PII and extract metadata.
process_zip: This script processes a file dump of documents in a zip file and stores them in the vector database with some metadata. The format of the zip file should be a flat zip file folder of docx, pdf, txt, md, pptx or csv files. You can provide custom metadata as a JSON string and flags to screen for PII and extract metadata.

Limitations

While the ChatGPT Retrieval Plugin is designed to provide a flexible solution for semantic search and retrieval, it does have some limitations:

Keyword search limitations: The embeddings generated by the text-embedding-ada-002 model may not always be effective at capturing exact keyword matches. As a result, the plugin might not return the most relevant results for queries that rely heavily on specific keywords. Some vector databases, like Pinecone and Weaviate, use hybrid search and might perform better for keyword searches.
Sensitive data handling: The plugin does not automatically detect or filter sensitive data. It is the responsibility of the developers to ensure that they have the necessary authorization to include content in the Retrieval Plugin and that the content complies with data privacy requirements.
Scalability: The performance of the plugin may vary depending on the chosen vector database provider and the size of the dataset. Some providers may offer better scalability and performance than others.
Language support: The plugin currently uses OpenAI's text-embedding-ada-002 model, which is optimized for use in English. However, it is still robust enough to generate good results for a variety of languages.
Metadata extraction: The optional metadata extraction feature relies on a language model to extract information from the document text. This process may not always be accurate, and the quality of the extracted metadata may vary depending on the document content and structure.
PII detection: The optional PII detection feature is not foolproof and may not catch all instances of personally identifiable information. Use this feature with caution and verify its effectiveness for your specific use case.

Future Directions

The ChatGPT Retrieval Plugin provides a flexible solution for semantic search and retrieval, but there is always potential for further development. We encourage users to contribute to the project by submitting pull requests for new features or enhancements. Notable contributions may be acknowledged with OpenAI credits.

Some ideas for future directions include:

More vector database providers: If you are interested in integrating another vector database provider with the ChatGPT Retrieval Plugin, feel free to submit an implementation.
Additional scripts: Expanding the range of scripts available for processing and uploading documents from various data sources would make the plugin even more versatile.
User Interface: Developing a user interface for managing documents and interacting with the plugin could improve the user experience.
Hybrid search / TF-IDF option: Enhancing the datastore's upsert function with an option to use hybrid search or TF-IDF indexing could improve the plugin's performance for keyword-based queries.
Advanced chunking strategies and embeddings calculations: Implementing more sophisticated chunking strategies and embeddings calculations, such as embedding document titles and summaries, performing weighted averaging of document chunks and summaries, or calculating the average embedding for a document, could lead to better search results.
Custom metadata: Allowing users to add custom metadata to document chunks, such as titles or other relevant information, might improve the retrieved results in some use cases.
Additional optional services: Integrating more optional services, such as summarizing documents or pre-processing documents before embedding them, could enhance the plugin's functionality and quality of retrieved results. These services could be implemented using language models and integrated directly into the plugin, rather than just being available in the scripts.

We welcome contributions from the community to help improve the ChatGPT Retrieval Plugin and expand its capabilities. If you have an idea or feature you'd like to contribute, please submit a pull request to the repository.
