Credits are Revision Time’s in-app currency for AI-powered features. The main use is automated answer marking — when you submit a written answer for AI marking, credits are deducted from your balance. Credits exist because AI marking runs on a Large Language Model (LLM), which has real running costs. The credit system keeps usage fair for all students.Documentation Index

Daily credits by plan
Every day your credit balance is topped up automatically based on your plan:| Plan | Daily credits |
|---|---|
| Basic | 10 credits |
| Pro | 50 credits |
| Ultimate | Unlimited* |
* Ultimate plan credits are subject to high fair-use limits. In practice these limits are generous and designed only to prevent automated or abusive usage, not to restrict normal revision activity.
Earn bonus credits
You can earn bonus credits on top of your daily allowance by submitting community revision questions that other students answer. When your questions are used, you receive extra credits. Bonus credits stack on top of your daily allowance. Keep in mind that bonus credit earnings are not guaranteed and will vary depending on how your questions are received. Don’t rely on this as a consistent source of credits.Reward wheel
Completing revision sessions may unlock a spin of the reward wheel. Spins can award bonus credits or other rewards. Check the app after finishing a session to see if you’ve earned one.Buy a credit top-up
