The Verdict
Grammarly is built for writers and students, with a focus on grammar and spelling. ProWritingAid targets authors and fiction writers and leads with grammar-check and style-reports.
Pricing is close: ProWritingAid starts at $10/mo versus $12/mo for Grammarly — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for students — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
