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. 🤷

Y'all need to stop telling people Grammarly is free to use and upgrade to pro for more features that's not true. You only get 100 free prompts per month unless you upgrade. What has been advertised on YouTube ads is incorrect and misleading. I have screenshots of my 100 free prompts used up and a recording of the YouTube ad. It's false advertising; it's not free, it's only 100 free checking prompts every 30 days. Then you pay to use the service. I would rate 5 stars, but the dishonesty is crazy.
