A living memory
for your AI.
Lattice is a desktop app that quietly keeps track of everything your AI should know — your projects, people, and notes — and feeds it to the AI tools you already use. Install it once; it organizes itself from there.
Free and open source. All install options →
What the app does
Remembers across sessions
Your AI starts every conversation already knowing your projects, people, and history — instead of from a blank page.
Organizes itself
It tags the people, projects, and meetings out of the tools you already use. No manual filing, no folders to maintain.
Ask in plain language
Search everything Lattice knows with a normal question — “what’s high-leverage to work on right now?” — and get an answer grounded in your real data.
Works with the AI you already use
Claude, Codex, and the rest read straight from Lattice. If your AI can read a file or call a function, it can read Lattice.
Your secrets & files, in one place
Keep credentials and documents in a vault the app manages for you — available to your AI when it needs them, private when it doesn’t.
Self-updating app
Double-click to install — no terminal, no Node.js. The app opens in its own window and updates itself on launch.
From your tools to a real answer
Your apps flow in. Lattice organizes. Your AI reads it and answers.
Lattice is the layer — MCP fills it, harnesses read it.
One layer in the middle
Lattice sits between the tools that produce your context and the AI that consumes it.
