Free AI grading, no credit card needed
The Free plan is a working account, not a demo. It reads handwritten papers from photos or a scanned PDF, marks each answer against your key or rubric, writes feedback on the page and builds a class report. You approve every mark before students see anything.
It stays free. Each month you get 10 AI gradings (one grading is one student's paper, up to 20 pages). When you need more, you choose Pro or School yourself. No card is stored and nothing starts charging on its own.
What you get without a card
- 10 AI gradings every month, renewed automatically.
- Up to 3 active assignments and 30 students.
- Handwritten sheets, typed answers, MCQs, diagrams and regional-language papers.
- Red-pen annotations on the scan, per-question marks with the reason for each, strengths and improvements.
- A private results page for each student and the class report with averages, hard questions and a reteach plan.
- The Claude connector and a free test key for the Grading API.

Frequently asked questions
Is a credit card required for the Free plan?
No. You sign up with an email or Google account and start grading. A card is only asked for if you choose Pro, School or a top-up.
Does the Free plan expire?
No. It is not a trial. The 10 gradings renew every month for as long as you use the account.
Will I be charged automatically later?
No. There is no card on file, so nothing can be charged. Upgrading is a separate step you take on the pricing page.
Can students use the Free plan?
Yes. A student can grade their own practice answers with the same 10 gradings a month. Results a teacher shares arrive on a private link and need no account at all.
Why does the school pilot take a card when the Free plan does not?
The pilot gives 200 gradings of the School plan for 30 days. A card lets each school run it once instead of being repeated across accounts. It is not charged during the pilot.
