Why have I reached a marking limit?
Your account allowance and shared AI capacity are separate.
Updated 8 October 2026
1. Account limits
Free has 6 AI credits per calendar month and up to 1 paper per UK day. Pro has 60 credits and up to 5 papers per UK day. A paper uses 3 credits and a new personal lesson uses 1. Credits reset on the first of the month and do not roll over.
2. Shared capacity
Markwise also protects a shared AI budget and provider quotas. An upgrade does not remove a shared outage or exhausted provider quota. Read the message shown to see whether to wait for an account reset or for capacity. Papers, saved feedback and revision links are still available.
