 Here're some of the project's features:
 
 - Start a Text Chat：Initiate a text chat with the ability to input written conversations, where the dialogue content can also be customized based on uploaded files.
-- Upload File: The choice between uploading locally or copying a remote link. Chat according to uploaded knowledge base.
 - Clear: Clear the record of the current dialog box without retaining the contents of the dialog box.
 - Chat history: Historical chat records can still be retained after refreshing, making it easier for users to view the context.
 - Scroll to Bottom / Top: The chat automatically slides to the bottom. Users can also click the top icon to slide to the top of the chat record.
