PyNote integrates Claude, an AI assistant developed by Anthropic, directly into the sidebar of JupyterLab 4 and Notebook 7 environments. Designed for users working within Jupyter notebooks, it enables interactive conversations with Claude about the current notebook, allowing users to discuss, plan, and make code changes without leaving the interface or switching tabs. The tool operates as a chat panel where users can ask questions or request code modifications related to their notebook. When Claude suggests an edit—such as adding a plot or modifying a code cell—the user can type 'apply' to accept the change, resulting in an in-place update of the relevant cell. This process is transactional, so a single undo action will revert an entire batch of changes. Edits are structured using stable cell identifiers rather than relying on cell indices, making the process more robust to changes in notebook structure. Users can continue chatting with Claude to iterate on suggestions or type 'cancel' to discard them, all without disruptive dialogs or popups. PyNote is distributed as a standard Python package installable via pip. 9 or newer. js setup or separate JupyterLab extension installation is needed. To use Claude, users must provide their own Anthropic API key, which is read securely from the Jupyter server process and never stored in browser settings or bundled with the package. Data sent to Anthropic consists only of cell source code, stable cell IDs, and chat messages; outputs, notebook files, and API keys remain local except when the key is used as an authentication header for API requests. PyNote is MIT licensed, and billing for Claude usage occurs directly through the user’s Anthropic account, with no intermediaries involved. The tool is aimed at Jupyter users seeking to enhance their workflow with conversational AI assistance directly within their coding environment.
