Ive been using Grammarly for about a month now and Ive noticed it fails to pick up on simple grammatical errors, such as: I sent an email to a potential employer today, and I was quite tired while I was writing it, so I wrote: Thanks again for taking the time to speaking with me today and Grammarly didnt catch the mistake. This is just one example of many, and now my employer things I cant write. Dont bother, just use Word.
