Fifty drafts — blog posts, essays, emails — each run through Undetectable AI, then scored on GPTZero, Originality, and Turnitin. We tracked score drops, factual errors, and how the prose read to a human.
On light-AI drafts, it reliably pulled scores under 20% on the simple detectors. The interface is fast and the "humanize" toggle is one click. For casual use, it does what the ads say.
On heavy-AI drafts it started rewriting facts and inventing transitions, the same failure mode as every one-click tool. Scores on Originality dropped less than advertised, and a human reader could still feel the smoothing. Two drafts came back with wrong numbers we had to fix by hand.
Useful as a first pass on easy text; not a substitute for a human edit on anything that matters. If you want the score down and the facts intact, a human-in-the-loop service (our $45 tier) is the safer bet. The $15 pack gets you the prompts to do it yourself.
