So what grammar checkers are good to use. I recently found www.Grammarly.com which was from a YouTube ad, I think. I Googled grammar checkers, and came up with a bunch, some claiming to be free, but I don't really want to install anything without recommendation. A long time ago in a galaxy far away, I had a DOS computer with WordStar or something. Then I got something, I think it was Webster's New World Writer, which was a word processor that had spell and grammar checking. It would give information such as reading ease scores, and how to improve my writing. It looks like Grammarly had a paid version, which will do that, but I'd rather not go into a subscription of paying forever... do I really need to update my grammar checker constantly?
