Grade your next worksheet or assignment for free.

Individual Teacher is for one teacher running their own classes — free for 14 days, self-serve, no setup call. School Pilot is an 8-week trial for a department of up to 3 teachers, with onboarding support and a final impact report at the end. Schools is full deployment across the school — LMS integrations, admin dashboards, custom contract. Most schools start with a Pilot, then move to Schools.

No credit card required. The trial is free. If you want to keep going, just let us know and we’ll work with you on pricing for your class, department, or school. No surprise charges, ever.

Your trial just wraps up — no automatic billing, no awkward handoff. If you want to keep going, just let us know and we’ll get pricing sorted for your class, department, or school. You can come back anytime.

About a minute per paper. A 22-paper class set takes around 22 minutes — including partial credit on the working, a margin comment per student, and the class diagnostic.

Both. The whole point is to read the working. Fermi grades approach, reasoning, and answer separately — and gives partial credit when a student set up the problem correctly but tripped at the end. The grade reflects how the student got there, not just where they ended up.

Never. Not Fermi’s models, and not the AI providers we use under contract. Student handwriting, rubrics, and graded work are encrypted, processed on your behalf, and excluded from training data — by design.

Yes — that’s exactly what School Pilot is for. Eight weeks free, up to three teachers, with onboarding and a final impact report. If it works for your school, you move to a Schools contract. If not, no obligation.
