Grammarly functions fine but being closed source, I have decided to abandon it since I'm pretty sure it maintains its "free" service by analyzing and selling whatever users are typing. If you're going to use this service, and open an account (which is optional), do yourself a favor and sign up using a Free email masking service such as SimpleLogin and using an open source password manager like Bitwarden.

If any Grammarly developers are reading this, please improve your transparency and make your products open source so that the ever growing privacy conscious community can embrace your service. Thank you!
