The AI humanizer and detector desk
Which AI humanizer is actually worth paying for?
We track 20 humanizers and 7 AI detectors: what they cost per 1,000 words, what the free tiers give you, and their refund terms, straight from each company's own pages. Hands-on tests of the free tiers start in November, with every output published.
