I write a lot - for documentation, articles and website copy. Grammarly helps to keep me on point with spelling, grammar, and anything else I might be missing while I'm pumping out content.
My favorite Chrome extension is Grammarly. It is a grammar checker that helps me to improve my writing. Grammarly can detect grammar errors, spelling mistakes, and punctuation errors. It can also help me to improve my style and clarity.
I have used Grammarly almost daily for the last 6 years. It is one of the first apps I put on any new computer. I don't send anything to anyone without it it being checked by Grammarly first!
