Gave it a quick try and it seems like a useful tool. I'm not 100% sure how accurate it is yet, will get a paid account to test more. An article I put in as a test that was written by AI but manipulated a few times and passed other AI detectors scored 99% AI in this app. Pretty huge difference! They way they quote pricing is misleading. They say 1 credit for 100 words BUT that is for AI detection OR plagiarism/readability. If you have both turned on, it is double that. Still a fairly reasonable price but not thrilled with how they quietly slip in a 100% price increase.

Heya Tech! The app used to be free, but it looks like it’s been updated to a paid only plan starting at $12.95 per month.

I've been using WriteHybrid and it really does just make AI text sound normal. It doesn't sound robotic, and I don't have to rewrite everything after.
