Locking in pricing today. What did we land on?
I don't have memory of that conversation.
↳ Lattice does.
Why Lattice
Three things you get the moment you install.
No new app to learn. Lattice sits inside ChatGPT and Claude and quietly turns every conversation into something you can use later.
Ask Your Own Thinking
Ask Lattice about patterns in your history. What problems do I keep hitting? What did I decide about X? It answers from your actual conversations.
Get Insights You Can't See
Weekly thinking reports. What topics dominate your mind? Where does your reasoning stall? What breakthroughs did you have? See your patterns.
Early users
Loved by power users.
Founders, researchers, and operators who run their day through AI — and refuse to keep losing the work.
Finally, a tool that actually remembers what I've built. I asked it what I'd decided about onboarding two months ago and it pulled the exact thread. Game-changer for anyone doing serious work with AI.
I stopped copy-pasting old chats into new ones. Lattice quietly pulls the right context when I need it. The weekly thinking report alone is worth the install.
The first ChatGPT add-on that didn't feel like a wrapper. It made my history feel like a library I can actually browse. I'm using it across both ChatGPT and Claude now.
