Developer Matteo Leonesi released a GitHub repo that wipes every conversation on Claude.ai in one go. The tool bypasses the UI’s limited “Select all” button, which only captures rows currently rendered, by calling the service’s internal API directly. Users run the script from the browser console after opening the /recents page.

To execute, users open https://claude.ai/recents, press F12, paste the contents of delete-all.js, and confirm a single dialog per organization. The script then iterates through all stored chats, deleting them slowly; the UI updates over several minutes. Keeping the tab open until the console prints “Finished” is essential, as navigation aborts the process.

The community response on Hacker News highlighted the script’s practicality for power users who maintain extensive Claude histories. By automating bulk removal, the tool saves time and reduces the friction of manual scrolling. As long as Claude’s internal endpoints remain unchanged, the script will continue to provide a reliable cleanup method for developers and researchers alike.

Leonesi’s repo includes a README that warns users about rate limits and advises against closing the tab prematurely. No authentication changes are required, but the script respects organization boundaries, prompting once per org. The open‑source nature lets anyone audit the calls, making it a transparent solution for managing Claude.ai data hygiene.
