How it works
The tool works by pasting text into a box and getting an instant verdict, with highlighted sentences that look AI-generated. It supports several languages and offers a Chrome extension, plus paid plans that raise the word limits and add batch checking.
ZeroGPT's free plan is generous compared with most detectors, which is its main appeal. Its accuracy is debated, like every detector, and it should be used as a rough guide rather than a final judgement on a piece of writing.
