Verdict
Decopy AI Humanizer has two major problems: it doesn’t fool AI writing detectors, and it oversimplifies everything to the point where the output sounds childish and unprofessional. That’s a real shame because the free pricing is genuinely generous, and the tool doesn’t introduce grammar errors like so many competitors do. As it stands, Decopy can be fun to play with (especially thanks to the sentence rewriting feature), but you shouldn’t expect it to actually fool anyone.
One free humanizer where the output actually changes how detectors score the text and where the writing does not sound like it was dumbed down for a middle school audience, my Clever AI Humanizer review walks through a tool that managed all of that without the oversimplification problem.
