About

DetectGPT is a browser-based writing analysis tool that checks pasted text or a public webpage for patterns associated with AI-generated writing. Users can submit up to 3,000 words per run and review an AI-likelihood percentage with highlighted passages. It accepts readable public-page URLs and is described for writing from ChatGPT, Claude, Grok, Gemini and other language models. A separate plagiarism checker compares submissions with public webpages and provides a similarity percentage, highlighted matches and source links. It serves students, teachers and writers reviewing drafts before submission or publication. Scores are indicators for review, not proof of authorship; plagiarism results reflect public-web matches, not private student-paper archives. The free service requires no account and has no daily check cap, with a 3,000-word limit per run.
