It has so many bugs, and they just don't care.
It is working only sometimes. Right now, to write this review, it started to correct and... stopped.
On another tab? Nothing. No sign of correction. I just need to find some other service like that that works.

Excellent in writting

OK

I keep trying to sign in to my existing account as prompted in an email. It says to sign up, when I click, change to sign IN, enter my email address, click continue, it just flashes and goes nowhere. When I go back to email the message is still there. Even now I am logged in but still prompts me to sign up.

Works When It Wants.

The app is very temperamental and unreliable. I thoroughly enjoy it when it's does work and not repeatedly requesting me to sign in, yet still doesn't activate when I click to sign-on and then click "Continue to Grammerly." It worked for a while when I re-installed TWICE. I read the troubleshooting instructions, but now the sign-in prompt is not showing up in order for me to follow the troubleshooting prompts. UGH!!
