A chat extension based on shared documents
Decision gist · record as of 2026-08-14
Yes, if you run JupyterLab >= 4.0.0 and want built-in chat for collaborative notebooks. Installation is low-friction, the extension is actively maintained, and it has no known security vulnerabilities. Verify that your deployment supports both the server extension and frontend extension installation before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires JupyterLab >= 4.0.0 and Python >= 3.10; both server and frontend extensions must be enabled after installation
- Low friction installation as a pure Python wheel.
- Depends on jupyter-collaboration, jupyter-server, jupyter-ydoc, and pycrdt for shared document support.

What it is and what it does
jupyterlab_chat is a JupyterLab extension that embeds a chat widget into the notebook interface, built on a shared document architecture. It registers a YChat shared document type and associates it with a frontend chat widget, enabling users to communicate within their JupyterLab session. The extension requires JupyterLab >= 4.0.0 and Python >= 3.10, and works by pairing a server-side Python component with a frontend NPM extension.
The package is designed for collaborative notebook work, where multiple users can chat in real time through the same shared document infrastructure. Installation is straightforward via pip, though the extension must be enabled on both the server side and the frontend side to function properly.
Use it for
- Enable in-notebook chat for collaborative data analysis sessions without switching between tools
- Provide real-time communication in shared JupyterLab environments for team-based research or education
- Integrate chat history with notebook documents for context-aware collaboration
- Support distributed teams working on Jupyter notebooks with synchronized messaging
