★★★★★Ogo· Jun 20, 2026
A unique App that makes your writing effortlessly great. I fully recommend Grammarly.
★★★★★cecilia ndu· Feb 1, 2026
Ohh! This is fantastic. I thought I knew it all but under Grammarly check, I found that I knew nothing. Thanks for the development of such an App.
★★★★★Jana Hossam· May 3, 2026
Truly great app. It covers exactly what I need right now because I’m studying Chinese and always checking for grammar mistakes. The tool helps a lot. And the Pass AI feature represents a solid part of my workflow too. Not sure why, but the corrections just feel more accurate than other things I've tried. Best app for this and definitely useful for my studies.
★★★★★Joy Cristobal· Feb 17, 2026
This grammar corrector is good, and the errors are well explained and there is even suggestion for a word replacement, only it was not really free you have to purchase it after 7 days or more.
★★★★★Zubair A· Feb 16, 2026

★☆☆☆☆ROANN VARGAS· Mar 21, 2026
Sucks! Haven't used it yet but the moment I try there are a lot of ads that popping.
★☆☆☆☆teerachai jarounsuk· Jul 22, 2026
I hate not being unable to turn off Dutch, Polish and italian in language options. Like ah yes I can totally speak all this language like why can't I turn them off specifically. Language English US I understand not being able to turn off but why these three.
