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 writing-assistant 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.
Feature-wise, Notion AI offers broader built-in capabilities (7 features vs 6), while Grammarly takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Grammarly has a slight overall edge — but if works directly within your existing notion workspace matters most to you, Notion AI may still be the right call.
