On the web, Claude’s Help Center documents a built-in way to select and delete multiple conversations. Open Chats and tasks, choose Select from a conversation’s three-dot menu, then use Select all and confirm Delete twice. The documentation does not establish whether one Select all action covers conversations beyond the displayed selection, so check your history afterward and repeat for any intended chats that remain. (Anthropic Help Center)
Delete all chats in Claude on the web
- Go to
claude.aiand sign in to the account whose chat history you want to clear. - Click Chats and tasks in the left sidebar.
- Hover over a conversation, click its ⋮ menu, and choose Select.
- Click Select all at the top of the list. To delete only some conversations, select their checkboxes instead.
- Click Delete, then click Delete again in the confirmation prompt.
- Review your chat history for any intended conversations that remain. If you find any, repeat the selection and deletion steps. Anthropic’s article does not say whether Select all covers conversations beyond the displayed selection, so do not assume one selection necessarily covers every chat. (Anthropic Help Center)
Android and iPhone
Anthropic’s Help Center describes multi-select deletion on Android, but the available instructions here do not establish the exact Android controls or confirmation steps. For a documented step-by-step bulk-delete procedure, use the web instructions above. (Anthropic Help Center)
For an individual conversation on iOS, open the chat list, touch and hold the conversation, tap Delete, and confirm. The cited Help Center instructions do not document an iOS multi-select or delete-all workflow. (Anthropic Help Center)
What chat deletion does—and doesn’t—mean
For Claude’s consumer products, Anthropic says a deleted conversation is removed from conversation history immediately and deleted from its backend systems within 30 days. (Anthropic Help Center)
Deleting chats is not the same as deleting your Claude account; account deletion is a separate process. (Delete your Claude account)
Chat history and API data are separate concerns. Anthropic’s Team and Enterprise guidance distinguishes removing chats from visible history from backend retention and points to separate information about deleting API data. That guidance does not establish that deleting a Claude chat deletes API data. (Anthropic Help Center: Team and Enterprise data)
Do you need a bulk-delete extension?
Claude’s web interface has a documented built-in multi-select flow, so a third-party extension may not be necessary. A Chrome Web Store listing advertises an extension that adds checkboxes to the Claude.ai sidebar for selecting multiple chats, but it is not an Anthropic feature. The listing does not provide a complete walkthrough or establish that it selects every chat; its privacy statements are developer disclosures, not independent verification. (Chrome Web Store listing)
