ProWritingAid review

ProWritingAid goes deeper than most grammar checkers on style. Beyond grammar, spelling and punctuation, Premium includes more than 25 analysis reports that look at readability, structure, overused words and sensory detail, plus a custom style guide, a custom dictionary and author comparison. You can set one of 40+ document types to tune the suggestions. The free plan is tight: each line editing report runs twice a day on 500 words, with 10 rephrases daily. Premium costs $10 per month billed yearly at $120, or $30 monthly, and a lifetime license starts at $399. The product has moved toward fiction. Story Canvas, Outline Crafter, Chapter Critique and community workshops are aimed at novelists, so a student or office writer pays for features they may not use. If you write books or long reports and want to study your own habits, it is excellent value on yearly billing.
