LLMnesia
Search all your AI chats locally and jump to exact messages
LLMnesia is a free Chrome extension that indexes and searches your AI chat history across ChatGPT, Claude, Gemini, Perplexity, Copilot, and more, all on your device. It imports past conversations, keeps new ones indexed automatically, and lets you open a universal search with Cmd/Ctrl + Shift + 9 to jump straight to the exact message you need.
Built local-first, it never uploads conversation data, requires no account, and gives you export and wipe controls. Upcoming Vault adds encrypted sync and cross-device memory.
