How it works

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.

No terminal, no setup

Double-click to install.

The app brings everything it needs. It opens in its own window — the Lattice workspace runs locally on your machine at localhost:4317.

Always current

Updates itself on launch.

Every time you open Lattice it checks for a newer version and updates in place. macOS and Windows today; on Linux, install via npm.

Give your AI a memory.
