What Zero GPT is
ZeroGPT is a free AI content detection tool that checks text, images, and videos to help tell human-made material from synthetic content. Rather than making absolute claims, it returns confidence scores and a clear verdict, and it is calibrated closely for English. Alongside the detectors, it offers a text plagiarism checker that traces reused published sources, a real-time grammar checker, and a video detector that analyzes clips up to 50MB frame by frame. You can run 3 free scans without registering, and the site points to paid pricing for more. It is aimed at students, teachers, and researchers who need to check originality and authenticity before publishing or grading.
What you can do with it
- Scan text passages to estimate whether they were written by a person or generated by AI.
- Check images and videos for signs of AI generation or editing, with confidence scores.
- Trace text against published sources to review originality and spot reused passages.
- Catch spelling, grammar, and style issues in a native editor as you type.
Who it is for
- Students who want to review their own work for accidental AI-generated passages.
- Teachers who need a second reference when checking assignment originality.
- Researchers and editors verifying the authenticity of sources and media.
What to watch out for
Detection is probabilistic, not a final verdict, so a score should inform your judgment rather than decide it on its own. False positives and false negatives are possible, especially on edited or mixed content, and results can vary by language even though the tool is tuned for English. Schools and platforms may have their own rules about AI use and about how detection tools may be applied, so using a result to accuse or penalize someone could conflict with those rules, and any consequences fall on the user. The free 3 scans are limited, and paid access may be needed for regular checking. Treat the output as one input among several, and confirm important decisions with human review.
