Make the keys bigger, please. On other devices, like Note, I don't have to think about where my thumb goes. The app itself works fine; there are issues with the correct spelling, and I have to redo entire sentences, but other than that, it works fine. I just have big thumbs, and the keys being bigger would help

This is just a basic sentient app. I would love it if you could just move the icon into a different spot and not have it down in the right corner, but the way I'm in right now would be ok to move it too in different rotations; that's all. This is very good. No bug or anything. And it DOES make sure all grammar is perfect. Can you also remove the ";" it's adding in every sentence I say? It's a bit weird.

It's an amazing app! The grammar checker is well configured and spot-on. I use the app whenever I write novels and to ensure I'm getting my words and punctuation right. The only thing that bothers me is that I can't get the Quillbot keyboard to pop up, even after reinstalling the app
