Wish I could give it a zero
Wish I could give it a zero. A written from scratch document shows 100% Ai despite other checkers indicating 0%. The more I paraphrase, the more Ai content there is! Such a crappy site

The AI detection was a complete joke. I thought upgrading my account would finally give me the reliable results I needed, but it was the same old crap. Dropped a ton of cash on this subscription, used just 9 credits, and then realized what a massive rip-off this was. And now, no refunds at all? What a scam!
Myst
EVERY SINGLE TIME I WRITE SOMETHING AND SPEND HOURS ON IT, it comes back as 100% ai generated - because I know how to use grammar I must be an ai this is the worst site ever and my school happens to use them so I have been failing my assignments due to you're stupid program. Just because my writing closely follows structured patterns or the way language models work - WELL GUESS WHAT COPYLEAKS - humans made that program!!! WOWWWWWW big shocker - worst site ever
