What does ZeroGPT do?

ZeroGPT is a free online AI text detector that tells you whether a piece of writing was generated by a language model like ChatGPT, GPT-5, Gemini, or Claude. You paste in text (up to 15,000 characters on the free plan) and it highlights each sentence it flags as AI-written, plus shows an overall percentage. The results page also lets you generate a PDF report you can use as proof.

Behind the scenes, ZeroGPT uses its own DeepAnalyse technology — a deep learning model trained on internet content, educational datasets, and synthetic AI samples. It supports detection across all languages, and you can upload multiple files for batch processing. Beyond detection, the same account gives you access to a full suite of tools: an AI humanizer, plagiarism checker, paraphraser, summarizer, grammar checker, and translator. That makes it a one-stop shop for writing quality control.

ZeroGPT is most useful for educators who need to check student work for AI use, content editors verifying originality, and writers who want to ensure their text reads naturally. You can also access the service through WhatsApp and Telegram for quick checks on the go. The free tier is generous, and paid plans unlock higher character limits and additional features.
