ZeroGPT

ZeroGPT at zerogpt.cc is a free web based AI text detector. A user pastes text into a box, up to 1,000 words at a time, and clicks Detect AI Text. The result labels the text as human written or AI and GPT generated and shows the percentage of the text judged to be machine written. The site also provides a split tool for dividing longer text into 1,000 word pieces, plus pre filled examples for human, ChatGPT, Gemini and mixed human and AI text. The detector shows sentence by sentence analysis, highlighting flagged passages in yellow, orange or red so a writer can see which parts to revise, and it reports a readability score. The vendor says it covers output from GPT models, ChatGPT and Gemini, and claims accuracy of up to 99 percent for its version 2.0 detector. It is aimed at publishers, marketers, students and educators who want to check whether content was written by a person. The site is presented as free and lists no paid plans. It carries advertising. This is a separate website from zerogpt.com, which offers a different, larger product suite with paid plans, and the pages shown do not state any relationship between the two.
