I removed Grammarly from my computer. It caused MS Word to stutter and hesitate, and it took too long to produce anything useful.

Grammarly spent most of its time making ridiculous synonym suggestions. And it wasted my time with circular suggestions.  When I followed Grammerly’s suggestion for revising a sentence, I sometimes got a new suggestion that would reproduce the original construction. I did like the “squinting modifier” advice, but not the hour the program took to find and point out the single occurrence. Grammarly gets a laugh or two, but I cannot recommend it for serious writing.

I do recommend the Grammar & Composition articles by Richard Nordquist on Ask.com. Five stars.
