The Verdict
Grammarly is built for writers and students, with a focus on grammar and spelling. Notion AI targets notion users and teams and leads with ai-drafting and summarization.
Pricing is close: Notion AI starts at $10/mo versus $12/mo for Grammarly — not a deciding factor on its own.
Grammarly has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Notion AI requires a paid subscription from day one.
Both tools are a solid fit for writers — 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.
