Most comprehensive grammar checker. For novelists + long-form writers: ProWritingAid Premium $120/year — 25+ writing analysis reports (pacing, dialogue tags, repetitive words, sticky sentences, etc.) optimized for fiction. Premium Pro $144/year adds 50 Sparks AI + Chapter Critiques + workshops. Lifetime $399 breaks even in ~3 years vs yearly.

What to Watch Out For
Grammarly AI prompt limits (100 free / 2,000 Pro / Enterprise unlimited) create usage tier decisions. For heavy AI users, Pro or Enterprise necessary. ProWritingAid Premium Pro vs Premium — Premium sufficient for most writers; Pro's 50 Sparks + Chapter Critiques + workshops only valuable for active novelists. LanguageTool Team plans scale 2-20 users then custom — verify team pricing. Hemingway Editor Classic (legacy) vs Plus (AI) are different products — verify which version matches needs. Ginger lost market share to Grammarly — verify active support before committing.
