Pricing FAQ

Is there a subscription?

No. Rubrica uses a pay-as-you-go wallet. Top up when you need to, spend $0.49 per assignment, get unlimited free revisions on the same assignment. Nothing recurs.

What does the $1.50 welcome bonus cover?

Around three full assignment feedback runs. Enough to try the product on a real assignment before deciding if you want to top up.

Are revisions really free?

Yes. Once you have paid for feedback on an assignment, every subsequent revision on that same assignment runs for free. Iterate until the rubric feedback looks right.

What if I run out of credit mid-semester?

You top up. Minimum top-up is $5. No monthly charge, no lock-in.

Are the free tools really free forever?

Yes. Rubric decoder, brief analyzer, reference verifier, citation formatter, grade calculator, and word counter are all free and do not require an account. That is different from the full rubric check, which costs $0.49 per assignment.
