Script Enables Bulk Deletion of Claude Chats
- •Matteo Leonesi released a JavaScript script to bulk delete Claude conversation histories.
- •The tool targets a limitation where Claude's UI only selects currently rendered chat rows.
- •The script uses unofficial internal API endpoints and requires keeping the browser tab active.
Developer Matteo Leonesi released a JavaScript utility on June 13, 2026, designed to bulk delete chat histories from the Claude web interface. The script was developed as a workaround for the platform's native interface, which features a "Select all" button that only targets chats currently rendered on the screen rather than the entire history. By automating the deletion process, the script allows users to clear their account data more efficiently.
Users operate the tool by navigating to the Claude recent conversations page, opening the browser's developer console via F12, and executing the provided JavaScript code. The process requires users to confirm dialogs for each organization linked to their account. The script functions by mimicking internal web app endpoints identified through network request monitoring.
The author warns that these endpoints are unofficial and not part of the public Anthropic API, meaning functionality could be disrupted by future platform updates. Users are advised to keep the browser tab open until the console displays a "Finished" message, as navigating away or refreshing the page will interrupt the deletion sequence. The tool is released under an MIT license and is intended solely for personal account management.
