JPT is a Chrome extension designed to streamline the execution of Python code within the ChatGPT environment. By leveraging the power of the Python ecosystem, users can seamlessly run code snippets using popular libraries such as numpy, scipy, and matplotlib. This tool utilizes a WASM-based Python interpreter, Pyodide, ensuring that all code execution happens within the browser, maintaining privacy with only the user and OpenAI having access to the code. The extension allows users to quickly edit and run Python scripts, enhancing the coding experience directly in ChatGPT.

While JPT offers significant functionality, it is still in development and may exhibit some bugs, particularly when handling infinite loops, which can cause the extension to freeze. Users can easily run Python programs with a simple command and can edit code on-the-fly, although these edits are temporary. Future updates are expected to improve the user experience further, including features like user input support, local filesystem access, and the ability to export chats as Jupyter notebooks.
