Built around false accusations
The worst thing a detector can do is call a student's own work AI-written. So our Likely AI line is set where only about 1 in 100 human texts in our tests cross it, and borderline work comes back Unclear instead of a confident number. The error rates are public, with how many texts each one rests on.
A good way to use it
- Check the work and read the highlighted passages, not just the Band.
- Compare with what you know of the student's writing: earlier work, drafts, work done in class.
- If you are still unsure, ask the student to talk you through the piece and how they wrote it.
We cannot tell you what Turnitin or your institution's tool will say, and a Verdict is never proof of authorship.
Student privacy
We do not keep the text. Only the result is stored, and without an account it is deleted after 30 days. See Privacy.
Questions
Can I use a Verdict to fail a student?
No, and our terms say so: a Verdict may not be the sole basis for any sanction. Use it to decide where to look and what to ask, then talk to the student about how the work was made.
Does it treat non-native English writers fairly?
Not perfectly. On our tests, research abstracts written in English by authors from Spain and Latin America were flagged more often than other human texts. Weigh a Verdict on a second-language writer with extra care.
Can I check a whole class at once?
Pro lets you upload PDF and Word files and run batches, with a Report per text. The free version checks one pasted text at a time.
