EXTREMELY OBTRUSIVE!!!! It forces itself onto you EVERY few seconds, even with floater off. Never provides reference to What or Where text correction is needed. Keeps you on track with grammar and spelling. Endlessly frustrating to have to try to edit a word in a section where it has marked words in green underline. Like a schoolyard bully, G will make it impossible to edit that area, except sometimes after multiple attempts. Extremely Extremely Extremely OBTRUSIVE and Forceful on every page.

2024: I like that it's more integrated but it crashed within the 1st few minutes of trying it again. Back to stock app I go. It can't handle highlighting text. 2021: Love the PC version and have been using it for several years. I have never been able to type on Grammarly's mobile keyboard. I'm not sure why, it just seems so difficult to type each word. Swipe text on here is terrible too. I'll be going back to my stocm keyboard.

It's just okay. It's not intuitive and does not learn users use of words very well, and doesn't pickup on choice of words commonly used after certain words or sentence beginnings. Also, if a mistake is made in the word you want, it doesn't give your any choices of the word you may want instead. I mean it will as you are typing, but once you realize it's the wrong word, it won't go back to the choices it presented. The original SWYPE from early 2000's by Dragon, was the BEST, but, is no lon
