How Credits work
How many Credits does each check use?
- Quick AI: 10 Credits / 1,000 words
- Turnitin: 600 Credits / check
- iThenticate: 2,500 Credits / check
- ZeroGPT: 20 Credits / 1,000 words
- Paper Precheck: 100 Credits / check
Quick AI and ZeroGPT use one block per started 1,000 words. For example, 2,300 words use 30 or 60 Credits respectively. Each service’s file and language limits still apply.
Do I need a subscription?
No. Both packs are one-time purchases. Buy only when you need more Credits, with no monthly commitment or automatic renewal.
Do I need separate balances for each service?
No. Both packs contain the same shared Credits. The examples show possible uses, not restrictions on what you can choose.
Can I use Credits for iThenticate?
Yes. An eligible iThenticate AI Writing Report uses 2,500 Credits / check. It uses the same shared Credit balance as the other services.
Do Credits expire?
No. Purchased pack Credits stay in your account until you use them.
When can I use my Credits?
Credits are added to your account after payment is confirmed. Choose a service, add your document and start your check. If a check fails, its reserved Credits are returned to your balance.
