Years ago I worked at a company where many people were using Grammarly. One of the top devs took a look at it, and saw that the text was sent to Grammarly's server unencrypted and warned everyone not to use it. Some still did.
At my previous engagement, a large number of staff spoke English as a second or third language, and Grammarly was prevalent. Even as a native English speaker, they wanted me to use it as a sort of proof reader. I'll admit that it caught some of my dumber mistakes, but I never felt comfortable using it. I could have proof-read my work better is all. Perhaps if I wasn't given mind-numbing work, the quality would have been better.
