LLMnesia is a local-first Chrome extension that indexes and instantly searches your AI chat histories across multiple assistants (ChatGPT, Claude, Gemini and others), surfacing prompts, code snippets, answers and links back to the original conversations so you can quickly retrieve past AI outputs; all indexing and search run entirely in your browser with no cloud sync, accounts, or tracking, keeping sensitive AI-generated content on-device; it’s ideal for researchers, developers, writers or any heavy AI user who needs fast, private cross-platform retrieval of valuable chat history.
