Lattice

Your second brain across ChatGPT and Claude — map, explore, and query your entire AI conversation history.

Lattice is your second brain for AI conversations. It quietly maps every chat you have with ChatGPT and Claude into one explorable canvas — so your best thinking is never buried in an endless scroll again. WHAT IT DOES • Conversation Atlas — every conversation becomes a visual branch tree. See each prompt, every edit, and the branches you explored at a glance. • One unified Library — ChatGPT and Claude chats are captured automatically as you talk and sit side by side, fully searchable. No exporting, no copy-paste. • Ask Lattice — ask a question across your entire history in plain English, or @mention specific conversations to compare them. Every answer cites the exact chats it came from. • Edits & branches preserved — re-rolled a response or rewrote a prompt? Lattice keeps each version so you can revisit the paths you didn't take. • Thinking clusters — Lattice groups related conversations into themes and surfaces the threads you keep returning to. WHY YOU'LL WANT IT If you do real work with AI, your history is a goldmine — but it's trapped across two apps and an infinite scrollback. Lattice gives that history structure and makes it searchable, so you can pick up where you left off, compare how your thinking changed, and stop re-explaining context to your assistant. PRIVACY Your conversations are stored locally in your browser — Lattice has no server that collects them. When you use Ask Lattice, the relevant context is sent to the AI provider you choose (Groq, OpenAI, Anthropic, or Google) using your own API key, solely to generate that answer. Works on chatgpt.com and claude.ai. Open Lattice any time with Ctrl+Shift+K (Cmd+Shift+K on Mac).
