ZeroGPT

by ZeroGPT

Free AI-content detector that scores text for the likelihood it was generated by ChatGPT or other large language models.

Content Detection & Safety Free; Enterprise/API pay-as-you-go plans

What is ZeroGPT?

ZeroGPT is an AI-text detection tool, not a translation product despite its name suggesting otherwise. Users paste or upload text and it returns an overall AI-likelihood percentage plus sentence-level highlighting of passages that look machine-generated, based on linguistic signals like perplexity (how predictable the word choices are) and burstiness (variation in sentence length and structure).

It targets multiple model families beyond ChatGPT, including Claude- and Gemini-style output. ZeroGPT bundles secondary tools — a plagiarism checker, paraphraser, summarizer, grammar checker, and its own chatbot — and offers an API and batch processing for businesses.

Like all AI detectors, its scores are probabilistic estimates and can misclassify human writing, so results shouldn't be used alone to make accusations of academic or professional misconduct.

Our take: ZeroGPT is best understood as a free, quick-check alternative to paid detectors like Originality.ai or Copyleaks — useful for a fast gut-check, but the vendor's own FAQ cautions that scores are estimates, not proof, and shouldn't be the sole basis for misconduct accusations.
