Ratings and reviews

Very useful if you text or send a lot of messages on your phone to people whom you need to sound professional to. They also have this app as an extension for your browser, and that thing is such a lifesaver for charting. It has its glitches here and there, but so far it's the best grammar corrector out there for both phone and PC at this moment in time. (All typos and grammar corrected with the tap of the widget icon)

I am unable to tap on the words in the rephrased version in the most recent update. I tried double-tapping and press-holding on the words, but other thesaurus words did not appear. Also, can you add a feature for the history for those documents saying like if you wanted to select all of the previous history documents so I can delete all at one time instead of deleting one at a time or five at a time?

This is just a basic sentient app. I would love it if you could just move the icon into a different spot and not have it down in the right corner, but the way I'm in right now would be ok to move it too in different rotations; that's all. This is very good. No bug or anything. And it DOES make sure all grammar is perfect. Can you also remove the ";" it's adding in every sentence I say? It's a bit weird.
