ClaudeSync

Sync your code easily with Claude.ai Projects without leaving your IDE.

About

One of the most underrated features of Claude.ai is "projects". You can sync your code with a project, and then simply talk to Claude about your code, without needing to worry about supplying context. ChatGPT has a similar feature, but only works with their "4o" model as of now, and is not as good as Claude.

Claude Sync aims to make it easier to use Claude.ai projects by directly letting you sync your code from your IDE, with features like auto-syncing, exclude/include files, and more.

Inspired by ClaudeSync by jahwag.
