★★★★★Ivan Thien (eggo)· Aug 14, 2026
Grammarly AI is such a lifesaver. Fixes errors, polishes your writing, and even suggests better ways to say things. Works everywhere and makes writing way easier. Totally love it.
★★★★★Kristi Otti· Aug 9, 2026
This is such a useful, helpful app that I use every day! I love it and when I get into writing my books again, it'll definitely be worth paying for the upgrade! Great job!
★★★★★Subbu· Aug 4, 2026
We are pleased to announce a significant update featuring a game-changing Voice-to-text functionality. Thank you for this enhancement. We request that you enable a persistent Voice-to-text floating button in addition to the existing one. Surely deserves 🌟🌟🌟🌟🌟
★★★★★Mark Feltham-Rickard· Aug 14, 2026
Have been using Grammarly for a while now. My spelling is getting better along with my Grammer. Sadly, because I am on a UK state pension, I am unable to purchase the full version. With luck, Grammarly will not kick me off for taking such a liberty. Thank you, Grammarly, for helping me to greatly improve my spelling and grammar. Something school was never able to do.
★★☆☆☆Steven Mueller· Aug 10, 2026
Constant bugs. For how much I pay they should be embarrassed. I have to regularly force close the app, uninstall it and reinstall it, works for a few days then it quits again. Just doesn't load.
★★☆☆☆gerielle sanchez· Jul 28, 2026
This app helped me a lot, it improved my grammar. But recently, whenever I'm going to delete a text, it kept joining the other words I type. For example, I delete this specific word then it will create a typo like this "wanttto". It adds an extra letter causing for me to rewrite my paragraph. And every time I do a paragraph that required's to do research about the topic, it keeps deleting the words I type as soon as I exit the app. It deleted my entire script which I worked hard on.
★★☆☆☆Karlie San· Aug 10, 2026
The keyboard version is much more helpful and consistent in correcting errors. The floating one is pretty useless, considering the fact that it DOES NOT react properly to the text and is late. Like, I already corrected the word, and it still insists on correcting it again. It's downgraded so badly.
★☆☆☆☆Kemal Arda Ayar· Aug 10, 2026
Can you guys let us use drafts from the web version to sync with this app, so we can keep writing on the phone? L am I using Grammarly for my fanfic story.
★★☆☆☆Rameen Nasir· Aug 4, 2026
