Cairn

Know where your AI-built project actually is.

Cairn helps you get your idea built and keeps you in control of it. As your AI writes more of the code, you read less of it, so Cairn shows what changed since you last looked, where it drifted from what you asked for, and what you have not reviewed. It keeps your open work in view and reminds you before things slip. It runs on your machine and your own key, and never hosts your code.

Cairn opens to everyone on August 8, 2026. Join the waitlist to hold your spot and be ready on day one.
