SlickWrite and ProwritingAid measure sentence-breaks differently, the Slickwrite measures from period to period, but the ProwritingAid treats a semicolon like a period. Both apps measure the variety in sentence length, but the apps measure differently. Paperrater sucks, for a creative fiction author; James Joyce does the best of authors I sampled, but his work doesn’t pass all the tests.
ProwritingAid notes how sentence transitions apply to non-fiction, so failure for a fiction writer in that statistic is meaningless; while, Paperrater never mentions the difference between fiction and non-fiction–and just fails you. Sentence transitions (i.e. meanwhile and therefore) are different from temporal transitions or transitions of place, but I notice most don’t explain the difference. Paperrater faults simple sentence starts, but I’m not sure you can do much about that without adding prepositions.
Paperrater faults simple sentence starts, but I’m not sure you can do much about that without adding prepositions. The app did show how I tend to tack transitional phrases on the end and less often begin the sentence with a transitional phrase (I.e. before, after, near, and etc…), so I saw one benefit.
