DetectGPT is a free, browser-based AI content detector. Paste a draft (up to 3,000 words per run) or enter a public page URL, and DetectGPT returns an AI writing report: a percentage showing how much of the prose looks machine-made, with flagged passages highlighted so you can see which lines still sound like a model.
No account, login or campus license needed. Paste text, upload a .txt, or analyze a public URL. Shareable result links and a plagiarism/similarity checker are included.
Best for students, writers and marketers who want to check a draft before someone else does.
We wanted a fast, honest AI checker that anyone can use without an account or paywall, so students, writers and marketers can check a draft and see exactly which lines sound machine-written.
