AI generation is the one metered part. Your allowance shows as a usage bar in your account and resets every week. Everything else in the table is not counted.
Need more AI usage?
A boost adds AI usage on top of your plan and never expires. It does not unlock Expert models, which follow your plan. Prefer to pay in BOT? Buy usage inside CAD Studio.
Questions
Is it really unlimited?
Chats, projects and exports have no practical limit on Pro and Max. AI generation is metered by a weekly allowance, so the strongest models cannot be run without bound. When Expert use reaches the allowance, Standard keeps working. We watch for automated and shared use.
What happens when I cancel?
You keep your plan until the end of the period you paid for. After that your account returns to Free.
Does unused allowance roll over?
The weekly allowance resets every week and does not carry over. Boosts never expire.
What if a renewal payment fails?
Bachs retries the charge and emails you a link to update your card. Your plan stops when the paid period ends if the payment still has not gone through.
Which payment methods work for subscriptions?
Subscriptions are billed in US dollars by card through Bachs. One-time boosts accept more methods at checkout.
