It's a good app. Helps with spelling errors and whatnot. Only gripe? You get two clarity corrections for free. Afterwards, you have to subscribe to get those. I remember when Grammarly let you have clarity corrections for free with spellchecking. The only thing you had to subscribe for was the VIP rephrase or restructuring. Miss those days, but the economy demands what it demands... Still a good app, wished it did large documents without issue.

Thanks for trying Grammarly for Android! We recently updated the generative AI experience, including changes to prompt limits. We understand this may feel like a significant shift. We’d also like to look into the issues you’re experiencing with large documents. Our Support team can help investigate at https://gram.ly/3vQJV2L.

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. 🤷
