This is an independent, non-sponsored comparison. For single-tool detail see our Grammarly review and ProWritingAid review.
Pricing
| Plan | Grammarly | ProWritingAid |
|---|---|---|
| Free | Yes — core grammar | Yes — 500-word checks |
| Paid | Pro $12/member/mo annual ($30/mo); Business ~$15/user/mo | ~$10/mo billed annually; lifetime option |
| Enterprise | Custom | Custom |
ProWritingAid is the better value at the paid line; Grammarly's per-member pricing adds up across teams.
Grammar & clarity
Both are accurate on surface errors. Grammarly's real-time suggestions across browser, docs, and desktop are unmatched for convenience. ProWritingAid is comparably accurate but shines on structural feedback.
Craft depth (the real difference)
ProWritingAid offers 20+ writing reports — pacing, sentence variety, dialogue tags, sticky sentences, genre conventions. For novelists and non-fiction authors this is the decisive edge; multiple 2026 author guides name it superior to Grammarly for fiction (aitoolkitpro, 2026). Grammarly stays shallower by design — it polishes, it doesn't diagnose craft.
