Originality.ai has one of the highest detection accuracy rates, particularly with GPT-3.5 and GPT-4 text. Its probability scoring gives a nuanced view instead of a binary yes/no.

Yes, but with some limitations. If the AI-generated content has been heavily edited, the detection rate may drop slightly.

Does it work with AI prompt generators?
