Start on the free plan
Every teacher with a verified school email can check 1,000 papers a month today. Talk to us when that is not enough, and say how many papers a term you expect.
Wrong flags in testing
At the standard setting, our detector flagged none of 1,928 human-written papers and essays it was never trained on. For a school checking 10,000 papers, that means no more than about 16 wrongly flagged papers at 95% confidence. At the sensitive setting the ceiling is about 28. This holds only for English academic and student writing like the test set, all written before 2022.
- Our detector, run v1_8_s2_seed303, standard setting (6%), measured 2026-09-15.
When the detector changes
The live detector can change. Its default line moved from 10% to 6% on 2026-09-15. Each result names the detector run that produced it: run v1_8_s2_seed303 today.
Who checked the numbers
We run and grade our own tests. No outside party has checked these results yet. The model card lists the date and detector run behind each test.
Student work
Human scores the text in memory and does not save it. Neither this site nor our detector keeps a copy of the papers you check.
What a flag supports
A flag from our detector is a reason to look closer. It is not proof that anyone cheated. Write that into the policy, so no grade or penalty rests on a flag alone.
