ChatGPT - Jupyter - AI Assistant is a browser extension for Chrome that provides various AI helper functions in Jupyter Notebooks and Jupyter Lab. Developed by Ties de Kok, this free extension is powered by ChatGPT and GPT-4.

With ChatGPT - Jupyter - AI Assistant, users can benefit from several primary functions. These include automatically adding comments, docstrings, and formatting to code cells, explaining the content of code cells in an ELI5 style, helping with debugging error messages, completing code snippets, providing code reviews with suggestions and improvements, allowing users to ask custom questions to ChatGPT, and even enabling voice commands for custom questions through the microphone.

The extension also offers keyboard shortcuts, making it more convenient for users to access its features. Although the extension is archived and no longer actively maintained by the developer, it is still available for use. However, the developer recommends switching to Jupyter AI instead, which is actively maintained by the JupyterLab team.
