What does the ProWritingAid dialogue check do?

Most dialogue tags, aside from "said" and "asked" break that cardinal rule of writing: show don't tell. If you write "Jane exclaimed" after her dialogue, you are depending on a word to get Jane's emotion across. Instead, show it to your reader with her actions. Describe how Jane's eyes bulge with shock. Make everyone in the room turn to look at her outburst. Use ProWritingAid to highlight all your dialogue tags and get your emotion across in a stronger way.
