What is ZeroGPT?

ZeroGPT is a free-first web toolkit built around one popular job: pasting in a passage and asking whether an AI wrote it. Its detector returns a percentage score with highlighted sections, and the same site bundles a plagiarism checker, paraphraser, summariser, grammar checker and word counter, which explains its steady search traffic from students and casual content writers worldwide.

Most quick checks are free without an account, with paid tiers adding batch uploads, higher limits and API access. Convenience is the appeal, but results can swing between runs and differ sharply from premium detectors, and the free pages carry advertising. Treat ZeroGPT as a rough first opinion on a text, not as evidence solid enough to accuse anyone of anything.
