ChatKeep — Backup & Search Your AI Chats

Automatic local backup of your ChatGPT, Claude & Gemini chats — full-text search and Markdown export. 100% on-device, no account.

Your AI chats are your work. One account flag and years of conversations can vanish — there is no export after a ban, the official export is manual, and sidebar search only matches titles. Finding an old answer means scrolling. ChatKeep is a safety net for your AI work. It quietly saves every ChatGPT, Claude, and Gemini conversation to your own device as you chat, then makes all of it searchable. PRIVATE BY DESIGN - Fully local: conversations are stored in your browser and never uploaded - No account, no sign-up, no email - No servers, no analytics, no trackers — the extension contains no network code at all WHAT IT DOES - Automatic backup: conversations are captured as you chat, with no action required - One library for ChatGPT, Claude, and Gemini - Full-text search across every message, not just titles - Clean reader view for every kept conversation - Export any chat — or the entire library — as Markdown or JSON - Import official ChatGPT data exports (conversations.json) - Star conversations and filter by platform WHY IT IS DIFFERENT Most export tools are manual, single-platform, or route your data through a third-party server. ChatKeep is automatic, covers the three major AI platforms, and is architecturally incapable of sending your data anywhere. HOW IT WORKS 1. Install. No sign-up required. 2. Keep chatting normally on ChatGPT, Claude, or Gemini. 3. Open the ChatKeep library anytime to search, read, or export. PERMISSIONS, EXPLAINED - Read and change your data on chatgpt.com, claude.ai, gemini.google.com: ChatKeep reads the conversation text on those pages only, in read-only mode, to build your local backup. It never types, clicks, or sends messages for you. - Storage: keeps your conversations and settings on your device. Free to use. Firefox support, Obsidian folder sync, and bulk tools are planned. ChatKeep is an independent product and is not affiliated with OpenAI, Anthropic, or Google.
