For students
Check your own writing
Read what our detector sees in your essay. If another tool flagged you, find out what a flag does not prove and what to ask for.
Checking your own work
Our detector does not score text under 50 words, and readings under 150 words are weak. It reads English academic and student writing only. Without an account, the check on the home page takes up to 1,200 words. A free account gives you 2,000 words a day.
- If a passage you wrote reads as AI-written, keep your drafts. Your drafts show how you wrote it. Don’t rewrite it to change the result.
What the verdicts mean
Human means the part of the paper that reads as machine-written is at or under your setting’s line. Mixed means some of it reads as machine-written or machine-edited. AI means 80% or more of it does. When this site says a paper was flagged, it got Mixed or AI.
If you were flagged
Ask which tool flagged your paper, at which setting, and ask to see the passages. A flag from any detector is a reason to look closer. It is not proof that anyone cheated.
- What helps in a meeting is showing how you wrote the paper: your drafts, your notes and the version history.
If English is not your first language
Our detector flagged none of 1,195 essays by English learners kept out of training as a fairness test. They come from one university English language program, written 2005 to 2012. It also flagged none of 600 more it had never scored, from collections whose other essays were partly used in training. That is a count, not proof of fairness.
What a Human result means
It is one reading from our detector. It is not proof either way, and it cannot tell you what another tool will say. Every human-written document we tested was written before 2022. Writing from after AI tools became common has not been tested, and neither has writing done with grammar checkers or translation tools.
What our detector does not do
Our detector checks writing. It does not change it.
