Who it's for
Best for
Teachers and lecturers checking essays and coursework for AI-written passages
Writers scanning drafts to identify and rewrite AI-flagged sentences
Not for
Researchers who need a single verdict solid enough to cite as proof of authorship
People with an urgent account problem who need an answer within hours rather than a day
Features
Sentence-level prediction map
Each scan returns a 0-100 human-versus-AI figure plus a colour-coded map marking passages that read as machine-written.
Document upload with OCR
Text can be pasted for a quick scan or uploaded as .docx, .png and .jpg files, with OCR pulling wording out of scanned pages and handwriting.
Detection in fourteen languages
Detection covers English, French, Spanish, German, Portuguese, Dutch, Polish, Italian, Romanian, Indonesian, Tagalog, Russian, Bulgarian and simplified Chinese.
Shareable authenticity reports
Scans produce clear, downloadable authenticity reports that can be printed, reviewed and shared for record keeping.
Plagiarism checker add-on
A plagiarism checker runs alongside the AI scan, and the findings can be combined into one printable report.
What users say
Pros
- Returns steadier verdicts than other detectors, which often disagree sharply on the same block of text.
- Cancelling a subscription is quick, and emailed questions get clear, professional replies from the team.
Cons
- Well-written, coherent human prose is flagged as AI, while text full of spelling and grammar errors passes as human.
- Verdicts shift with text length, editing and writing style, so one result is not solid proof of authorship.
- Emailed replies take up to a full day, which is painful when an urgent account issue needs fixing fast.
