Description
Private ChatGPT & Claude archive in your browser. Offline search. Chats stay local; optional Gumroad license check only. Your AI chats are worth keeping. ChatCellar saves your ChatGPT and Claude conversations into a private archive that lives in your own browser, so you can find and reread them any time, even offline. WHAT IT DOES • Save this chat: open a conversation on ChatGPT or Claude, click the ChatCellar button, done. Save it again later to update your copy. • Auto-save (optional, off until you turn it on): saves the chat you have open once a reply has finished. • One library for both: every saved chat in one place, with ChatGPT and Claude side by side. • Full-text search: find any word in any saved chat. Search ignores case and accents, understands “quoted phrases”, and can filter by ChatGPT or Claude. Matches are highlighted. • Read offline: code blocks, lists and formatting are kept. Claude’s “Thought process” is saved too, if you had it open. • Export and back up (Pro): download a chat as Markdown or JSON, export everything as a .zip of Markdown files, or make one backup file of your whole archive. • Restore (free): bring a backup back into ChatCellar at any time. PRIVATE BY DESIGN • Your chats stay in your browser. No account, no analytics, no tracking. • The only network request is an optional license check with Gumroad when you activate or re-verify a purchased key (license key only, never your chats). FREE AND PRO • Free: keep up to 25 chats, with search, the library, auto-save and restore. • Pro, $19 one-time (no subscription): unlimited chats, plus Markdown, JSON and .zip export and full backups. GOOD TO KNOW • Works on chatgpt.com and claude.ai. • Claude artifacts (the side panel) are not saved in this version. • Chats live in this browser profile. Uninstalling removes them, so make a backup first. • ChatCellar is independent and isn’t affiliated with OpenAI or Anthropic.
