Claude Cleaner: bulk delete Claude.ai conversations

Claude.ai stores every conversation you have with the model in the sidebar. Deleting them one by one is fine for a handful, painful for a few hundred. The official UI offers no multi-select, no range delete, no "clear all".

Claude Cleaner is a Chrome extension that adds bulk delete to the Claude.ai sidebar. Hover a conversation, get a checkbox. Pick a range with Shift+Click. Hit Delete Selected, watch a progress bar process the rest.

What it does

• Checkboxes on every conversation in the Claude sidebar. They appear on hover so the normal UI is not cluttered.
• Shift+Click range selection: click one checkbox, hold Shift, click another, everything in between is selected.
• Bulk delete: a Delete Selected button appears once at least one checkbox is ticked, with the count of selected conversations.
• Real-time progress bar so you can see how many of N have been deleted and walk away.

Privacy

The extension runs entirely in the browser:

• 💡 No data leaves your machine. The extension calls the same delete endpoint that the Claude UI uses, just in a loop over your selection.
• No tracking, analytics, or telemetry.
• The manifest declares zero permissions other than running a content script on claude.ai.
• It does not read message content; it only operates on the conversation list.

3. Click the checkboxes for the conversations you want to remove. Shift+Click to grab a range.
4. The Delete Selected button appears at the bottom with the current count.

⚠️ Delete is permanent. Claude.ai has no trash and no archive. Once a conversation is gone, it is gone. Review your selection before confirming.

When to use it

• Periodic clean-up so the sidebar stays readable.
