Lattice – AI-powered analysis and organization for system design diagrams

Summary: Lattice is a Chrome extension that applies AI to system design diagrams, enabling organization into collections, architecture evaluation, and detection of design issues. It supports multiple analysis modes, auto-saves history, and exports data locally with privacy via a Gemini key.

What it does

Lattice organizes diagrams, primarily from Excalidraw, into collections and uses Gemini AI to evaluate architecture, identify missing components, and provide logic critiques. It features context-aware feedback, auto-save, and ZIP export of data stored locally.

Who it's for

It is designed for system designers and engineers who create and review architecture diagrams and want to maintain active, verifiable design assets.

Why it matters

Lattice prevents diagrams from becoming unused documents by enabling ongoing validation and structured management of system designs.
