Average rating

I was panicking at 2am before a submission. Proof humanized my entire intro in 10 seconds and it passed GPTZero with flying colors. This app is literally a lifesaver.

ZeroGPT was charging me $8 a month for the same thing. Proof AI is $4.99 and honestly feels way better built. I switched and never looked back.

The AI detector told me my entire essay was 89% AI. I used the humanizer, re-checked, and it came back 4%. Submitted with zero stress. Incredible tool.
