Subscription and usage
AI features depend on sign-in, plan, and current usage. Knowing those states makes it faster to see why the assistant is missing.
You need a signed-in account, either free or paid. The Assistant view can show remaining usage and warn when the balance is low or empty. When you hit a limit, assistant actions pause until you manage the account.
If the assistant disappears unexpectedly, confirm you are logged in, the plan is active, and usage remains. Account management links in the app go to subscription status.
The credit quota is reviewable in the settings panel (Cmd/Ctrl+,).
Sign-in and access problems overlap with Common problems. How the assistant works is in AI assistant.
