ZeroGPT
FreemiumAI text detector with a humanizer, plagiarism checker and writing tools
What is ZeroGPT?
ZeroGPT checks whether a piece of text was written by models such as ChatGPT, Gemini, Claude or DeepSeek and highlights the sentences it thinks are machine-made. Students, teachers and editors use it alongside its paraphraser, grammar checker and summarizer.
You paste up to 15,000 characters or upload files, and the detector returns a percentage gauge with flagged sentences plus a downloadable PDF report. Batch uploads are checked automatically in the dashboard, and the site says detection works across languages.
The same account also includes an AI humanizer, plagiarism checker, translator, email helper, and detectors for AI images and video. An API covers the detector, plagiarism checker, paraphraser, summarizer, grammar checker and translator for organizations that want to build it into their own systems.
