JPT for Web

What this Chrome add-on does

JPT is a Chrome extension that brings Python execution into the ChatGPT interface. It makes it simple to run short Python snippets and take advantage of widely used scientific packages so you can prototype, visualize, and test code without leaving the chat window.

Under-the-hood details

The extension embeds a WASM-powered Python environment (Pyodide) so code runs inside your browser. Execution is handled client-side via that interpreter; chat interactions with OpenAI remain the only external exchange tied to the session.

Main features and supported libraries

• Interactive plotting and numerical work with toolsets like matplotlib, scipy and numpy.
• Fast edit-and-run workflow: modify a script in the chat and execute it immediately.
• In-browser execution via Pyodide, so no remote Python server is required.

Known limits and current drawbacks

• The extension is still under active development, so you may encounter glitches.
• Long-running or infinite loops can make the extension unresponsive or cause it to hang.
• Edits made during a session are transient; they don’t persist beyond the current chat unless exported.

Planned improvements

• Adding support for prompting the user for input during program runs.
• Providing optional access to a local filesystem for reading or saving files.
• Exporting conversations or code as Jupyter notebook files for later use.

Recommended alternative

• SourceAI (paid) — suggested as a commercial option for users who want a more mature, supported product.
