Edit - For anyone wondering how to still use Grammarly, the Samsung keyboard has it integrated and it works fine. Just delete Grammarly so that the useless floating thing goes away. Used to work great with the keyboard. Now, for some reason, you decided to make it worse. The widget is bad. At least give us the option of using the keyboard. In the widget, we can't even see where the problem is. It just says what it is but you can't go to it in the text which makes it almost useless.

Good when it works. It has four issues. 1. The bubble doesn't always appear. 2. If in bundle mode you can't deselect a supposed error, you have to reject all the errors and the go and make changes manually. 3. Sometimes it replaces your writing with gobolygook that makes no sense. 4. You have to check individual paragraphs instead of everything at once. This gets time consuming if you have an entire page of writing.

I loved having 100 free rewrites per month. It was a huge help for me because I have dysgraphia. The rewrite suggestions weren’t perfect, but they gave me a solid starting point and it was easy to make my own edits. Unfortunately, the recent update killed it for me. There’s only 1 free rewrite per day, and I’ve also noticed a drop in the quality of the suggestions. With the limit at 1 per day and the results less helpful, my free rewrites feel wasted. Plus I'm already on a tight budget. 🤷
