Quick review
GPTZero highlights sentences that look AI-written and has a Chrome extension. The site claims high accuracy and says millions of teachers and students use it. No AI detector is perfect, so treat results as a guide and not as proof. We have not tested the tool, so this review is based on the public site.
- Pros: a free plan, sentence-level highlights, and a browser extension.
- Cons: the free plan is small, and detectors can be wrong.
How to start
- Open the site with the button.
- Paste your text into the box and scan it.
- Check the plans if you need more than 10,000 words a month.
