Frequently asked

Will my account stop working if I hit a limit?

No. We return a clear 429 (and a friendly inline notice) telling you which limit was hit and when it resets. The rest of the app keeps working.

How do you count AI usage?

One chat message = one increment. One AI suggestion refresh = one increment, but cached re-renders are free. Monthly counters reset on the 1st (UTC).

Do you charge for read-only viewers?

No!

What payment methods do you accept?

Cards (Stripe) for Pro. Bank transfer / PO / annual invoice for Enterprise. (Currently Disabled)

Can I cancel any time?

Yes. Cancel from Settings → Billing. Pro stays active until the end of the current period, then drops to Free.

Is the AI trained on my data?

No. Your documents stay in your knowledge base and are only used to answer your team's questions. We do not train models on customer data.

Start free. Upgrade when you need more.

Project Brain pays for itself the first time a teammate doesn't have to ask "where's the latest spec?"
