Is It AI?
What Is It AI? is
Is It AI? screens written work for AI risk for teachers, tutors, schools and students. It marks passages that raise concerns and explains those flags in plain English. Users can paste text, enter a URL, or upload DOCX, PDF, TXT and MD files up to 10 MB. Its described method combines a language-model judge, eleven locally calculated stylometric measures and a curated phrase library. The maker says results are probabilistic signals that may include false positives or false negatives, so they are not proof of AI use. Submitted text is said to be processed and immediately discarded, not retained or used for model training. The browser service is designed for UK education and English-language writing, with no LMS integration yet. A first scan is free without an account; paid choices include one-off checks, monthly teacher plans and annual school plans.
