Claude Cleaner

Allow deleting multiple chats with a progress indicator in Claude.ai.

Claude Cleaner - Bulk delete chats, Cowork sessions and artifacts on Claude Claude lets you delete one conversation at a time: open the menu, click Delete, confirm, then start again for the next one. With a long history, that is an afternoon. Claude Cleaner adds checkboxes and a Delete selected button, so you clear hundreds of items in one pass. NEW IN VERSION 3 • Delete artifacts from the Artifacts page • Delete Claude Design projects from the same page • Chats and Cowork sessions, as in version 2 WHAT YOU CAN DELETE • Chat conversations • Cowork sessions • Artifacts (an artifact made inside a chat goes with its chat, and the confirmation tells you how many chats are deleted) • Claude Design projects you own HOW IT WORKS 1. Open claude.ai. The extension is active, nothing to set up. 2. Hover a conversation in the sidebar. A checkbox slides in. 3. Click it to select. Hold Shift and click another one to select everything in between. 4. Click Delete selected. A progress bar counts each deletion. On the Artifacts page, each card gets a checkbox, with Select all and Clear at the bottom of the screen. RELIABLE ON LARGE CLEANUPS • Deletions run in parallel and retry when Claude slows them down • An item that fails to delete stays in place, unchecked • Your selection stays when Claude redraws the sidebar • Claude's layout is untouched until you hover a row PRIVACY: NO PERMISSIONS The manifest declares "permissions": []. Chrome grants the extension no permission at all, so these points are built in rather than promised: • Runs on claude.ai only • No data leaves your browser • No tracking, analytics or telemetry • It never reads the content of your conversations It only does what you could do by hand in Claude, with your own session. IMPORTANT Deletion is permanent. Claude has no trash and no undo. Check your selection before you confirm.
