Ratings and reviews

I am beginning to think that this app is a scam. when I first tried this app I was able to upload a file to check if it was written using an AI. it used to work just fine, but after subscribing, I cannot upload any file at all. all I can do is copy paste now. it should ve able read an uploaded file

I paid for subscriptions hoping to have a one-click experience with the paraphrasing tool, but after paraphrasing, repeatedly humanizing, and copying out the output, the AI detector tool still says the output is a hundred percent AI generated. I can't find any useful applications for the service after spending my hard-earned money, and the editor is consistently slow and unresponsive.

It just took forever to type something because the keyboard just is not very convenient with its layout, it seems to analyze as your typing. Just let me type it out and analyze it after. I've been using SwiftKey for years and this just felt like a step back. I was assuming it would work like Google keyboard or SwiftKey, but just enhance it. Definitely needs fixing.
