Two third-party JupyterLab extensions ship with the platform alongside the Syntasa-built ones.
Zip extension
Right-click a folder in the JupyterLab file browser to zip it into a single archive without leaving the browser. Useful for downloading a directory of artifacts at once, packaging an analysis to share, or backing up a folder before risky edits. The extension handles RTC drive-prefixed paths so it works on workspaces with collaboration enabled.
Jupyter AI
The standard Jupyter AI extension is installed across the platform's kernel images at version 2.31.7. It exposes the usual chat panel and cell magics for sending prompts to LLM providers your admin has configured. Refer to the upstream Jupyter AI documentation for prompt syntax and provider setup; nothing in the platform's integration is custom.
