Memex

Your multi-AI memory: search, group & ask across ChatGPT, Claude & Perplexity — local-first and private to you.

Memex — Search, organize & remember all your ChatGPT, Claude & Perplexity conversations. Your AI chats are full of great answers you'll never find again. Memex turns ChatGPT, Claude, and Perplexity into one searchable memory — so everything you've ever asked is one search away. 🟢 THE PROBLEM You've had hundreds of conversations across ChatGPT, Claude, and Perplexity. The answer you need is in there somewhere — buried across three sites, three histories, impossible to search. Your AI history is a goldmine you can't dig into. 🟢 WHAT MEMEX DOES Memex indexes your past conversations from every supported AI into a single library you can search, organize, revisit, and even question — right from your browser. ✨ KEY FEATURES 🔍 Cross-AI search Search every conversation from ChatGPT, Claude, and Perplexity at once — by title, keyword, topic, tag, or note. Smart ranking and synonym matching (search "bug", also find "error", "crash", "issue"). Filter to one AI with provider tabs, or search them all. 🗂️ Organize your history Let AI sort your chats into clean thematic groups, or build your own. Add tags and notes, nest sub-groups, star favorites, and operate on many conversations at once with bulk move / tag / delete. 💬 Ask Memex Ask a real question — "what was that book rec from last week?" — and get an answer drawn from your own past conversations, with citations that jump you back to the source chat. No relevant match = no charge. 📝 AI summaries Get a 2-3 sentence recap of any conversation, stored and reusable. Drop it into a new chat as context in one click. ⚡ Prompts, chains & sessions Save your best prompts and multi-step chains, and paste them into any AI with one click. Pin conversations and messages to an active session and restore them when you come back. 📤 Export & sync Export your whole library to Markdown, PDF, JSON, or Notion. Tags, notes, groups, and prompts sync across all your devices. 🤖 One workflow, every AI ChatGPT, Claude, and Perplexity today — more assistants on the way. One library, one search, all your AIs. 🔒 PRIVATE BY DESIGN Searching, grouping, and tagging happen entirely on your device — your conversations are indexed locally and never leave your browser. The AI features (sort, summarize, Ask Memex) are opt-in: only when you use one is that content sent to be processed. You're always in control. 🟢 WHO IT'S FOR Researchers, writers, developers, students, and founders who live in AI chat and are tired of losing their best conversations. Open Memex from your toolbar or with a keyboard shortcut, on the AI sites you already use. 📪 Questions or feedback?
