What Users Say After Switching
"Undetectable AI kept getting caught by Turnitin for my Masters thesis. Switched to AI2Human, passed on the first try. The Heavy mode is exactly what I needed."
"I was paying $24.99 a month for Undetectable AI and still had inconsistent results on Originality.ai. AI2Human's Pro plan costs $10 less and the results are far better."
"The Light mode is great for blog content that doesn't need much rewriting. Undetectable AI only has one setting — too aggressive for SEO articles where I want to keep my original voice."
