How credits & billing work
- 1 credit = 1 graded submission. Re-grading a submission uses a new credit.
- Credits reset each billing period — no rollover.
- Hit your monthly cap? Grading pauses with an upgrade prompt — uploads and review are never blocked.
- Every school is billed independently — its own invoices, billing portal and trial clock.
- Running low? Credit top-ups (from $15 for 25 credits) never expire and kick in after your monthly allotment.
Questions, answered
The things Ontario teachers and centre directors ask us first.
What exactly is a credit?
One credit grades one submission. A grading run for a class of 28 uses 28 credits; re-grading a student later uses one more. It's the simplest possible unit — no per-page or per-question maths to track.
How does the free trial work?
Every plan starts with a 3-day free trial that includes 8 grading credits — enough to grade a small class set. Cancel anytime from your billing page.
What happens when I hit my monthly credit cap?
Grading pauses — uploading work and reviewing already-graded submissions are never blocked. Buy a credit top-up right in the app (from $15 for 25 credits — top-ups never expire) or upgrade your plan. Monthly credits reset each billing period and don't roll over.
Can I buy extra credits without upgrading?
Yes. Top-up packs — 25 credits for $15, 100 for $55 or 250 for $125 — are one-time purchases from your Billing page. They never expire, and they're only drawn on after your monthly allotment is used up.
Can I change or cancel my plan later?
Yes. Switch tiers, move between monthly and annual billing, update your payment method or cancel — all self-serve from your billing page. Changes prorate automatically.
We run multiple schools or campuses — can we keep them isolated?
Yes. Each school gets its own branded subdomain and isolated environment, with its own billing. Beyond the School tier's 500 credits a month, or several campuses under one agreement, talk to us about Enterprise — hello@ontariogradingai.com.
Can it grade handwritten or scanned work?
Yes — scanned pages are read with vision OCR. Because scans cost more to process, there's a sensible per-assessment page limit on the trial and entry tier so a single huge upload can't run away with your credits.
Which subjects and grades are supported?
The full Ontario catalogue — 65+ course codes across Grades 7–12 plus language courses — with native Knowledge / Thinking / Communication / Application categories. Maths, sciences, English, humanities, computer science and more.
Do I have to connect a learning-management system?
No. The core flow — upload, grade, review, export — is fully LMS-free. Schools that want it can switch on an optional Moodle connector on the School tier; it's off by default.
