AI Detector

AI Detector is an online AI text detection tool at aidetector.app. You paste in a passage and it judges whether the writing looks like output from a large language model. The site says it recognizes content from systems such as ChatGPT, Claude, and Gemini, and it reports 99.9% accuracy in its own description. Alongside that, it bundles plagiarism detection and source verification, so originality and provenance can be reviewed in the same place. There is a free version, and because everything runs in a browser there is nothing to install. The stated audience is educators, content creators, and recruiters who need a fast read on written material.

- Check a submitted text for signs of AI generation.

- Run plagiarism and source checks in the same session.

- Get a report you can discuss with the person who wrote the text.

- Educators reviewing essays, assignments, and other written work.

- Editors and creators who need to verify originality.

- Recruiters and hiring teams screening written submissions.

Detection tools make mistakes, and the 99.9% figure is the vendor's own claim rather than an independent result, so treat it as marketing copy. A flagged text is not proof, and a clean text is not proof either. If you use it on student work, follow your school's academic integrity policy and give the writer a chance to explain, since decisions based only on detector output can be challenged and responsibility for them stays with you. The same applies to hiring and publishing decisions. Free version limits can also change, so check the current rules before you rely on the tool for high volume review.
