LLMnesia - Search All Your AI Chats Across ChatGPT, Claude, Gemini & More

Local-first search index for your AI chat conversations across ChatGPT, Claude, Gemini, and more.

Stop losing your best AI conversations. You have had hundreds of chats across a dozen AI tools, from ChatGPT and Gemini to DeepSeek and Character.AI. The research from last month. The code fix from March. The brainstorm you swore you would come back to. It is all still there, but none of these tools let you search across them, and none of them talk to each other. So you scroll, you re-ask questions you already answered, and you copy-paste the good answers into a notes app just to find them later. LLMnesia fixes that. It captures your conversations as you use them, builds a private search index right inside your browser, and lets you find anything across every platform in one search box. WHAT IT DOES - Search every message across all your AI chats at once, by keyword or by meaning. Semantic search finds the chat even when you do not remember the exact words, so you stop re-asking questions you already settled months ago. - Highlight any passage in a chat and save it as a memory, then drop your saved memories into a future chat in one keystroke, instead of hunting through a notes app. - Open the toolbar popup and search straight away, without being on a chat site first. Your most recent conversations are shown the moment it opens. Import your existing history in one click from any supported platform, or load an export file when the live import is too slow. - Star chats, bookmark results, and jump back to the exact point a saved memory came from. PRIVATE BY DESIGN Your conversations are indexed on your own device and never leave it. There is no cloud copy of your chats, no account required to use the free extension, and no conversation content sent to our servers. Search runs locally, in your browser. Your history is yours: it is not locked inside whichever tool you happened to use that day, so switching models never means starting from zero. COMING SOON Vault: encrypted, zero-knowledge sync so your history follows you across devices, plus a private backup you can restore if a browser, a profile or a machine ever lets you down. The server stores only ciphertext it cannot read. Founding members lock in half price for life. Join the waitlist at llmnesia.com/vault MCP: right now your AI tools are blind to everything you did in other tools. Soon you will be able to connect LLMnesia to any MCP-compatible tool, so it can draw on your entire history, for free, with nothing leaving your machine. Twelve platforms are supported today and more are added regularly. Don't see yours? Email hello@llmnesia.com and we will look into it. Questions or a feature request? hello@llmnesia.com.
