Write Lint runs on Apple's on-device Foundation Models out of the box. No servers, no telemetry, no training data. The model is already on your machine — we just give it a nice place to live.
Want a different model? Bring your own Claude or OpenAI key. Your key, your account, your call — Write Lint never sees it and never charges for it.
Default mode: zero network calls
No accounts, no subscriptions, no logins from us
Works fully offline — even on a plane
