* Enterprise plans are subject to a fair-use ceiling to prevent runaway costs. We will always reach out before throttling.
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.
One chat message = one increment. One AI suggestion refresh = one increment, but cached re-renders are free. Monthly counters reset on the 1st (UTC).
No!
Cards (Stripe) for Pro. Bank transfer / PO / annual invoice for Enterprise. (Currently Disabled)
Yes. Cancel from Settings → Billing. Pro stays active until the end of the current period, then drops to Free.
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.
