The web detector supports basic scans on-page and a more advanced scan for signed-in users. The product pages also describe shareable reports, sentence-level results, file upload, URL import, and plagiarism checking, while the API page adds multilingual support and additional endpoints for plagiarism, fact checking, and AI image detection.
