An excellent tool. I find it much better and more streamlined and intuitive than Grammarly. I use it to proofread my chapters for my novel writing and as someone who always struggled with grammar and punctuation, this is a lifesaver. It's simply a click to fix the errors and the dictionary feature is a lifesaver when it comes to character names, so I can be assured that it won't keep marking them wrong when they have a unique spelling. I love being able to edit right in browser, rather than only having to use it in Google Docs. As for the downside, it does occasionally delete a word or punctuation if you click to replace it with the recommended option. That's a slight annoyance, since it's not always apparent something is missing in your text. The only thing I can think of that causes this, is if you click to replace too quickly. If this happens, and I catch it, it's simply easy enough to slow down a little.
