Free plan on mobile, API, and AI assistant

The same Free allowances apply on the website, the mobile apps, the REST API, and the AI assistant.

Mobile

There is no in-app purchase. Usage is visible in the app. Upgrade opens web checkout.

API and AI

An expired subscription is no longer a connection reject. Free accounts can authenticate. When a cap is reached, the API returns 402 plan_limit_reached. The assistant reports the limit as an answer, not a crash.
