Key Facts
Notion AI and Grammarly approach writing assistance from opposite ends: Notion AI generates and transforms drafts inside your workspace, while Grammarly polishes text everywhere you type. They overlap less than their shared "AI writing" label suggests.
Notion AI, at $10 per member monthly as an add-on, works within Notion pages. It drafts documents from prompts, summarizes long pages, translates, extracts action items from meeting notes, and rewrites selected text in a specified tone. Its power comes from context: ask it to draft a project brief and it draws on the databases and pages in your workspace. For teams whose writing already lives in Notion — specs, wikis, meeting docs — it reduces the blank-page problem and the summarize-and-file chore. Its limits: it exists only inside Notion, its editing suggestions are generative rather than corrective, and it will not check your email or Slack messages.
Grammarly at $12 monthly is the everywhere-editing layer. Browser extensions and desktop apps check grammar, spelling, punctuation, and tone across Gmail, Word, Slack, LinkedIn, and virtually any text field. Its suggestions are corrective and conservative — it fixes errors and flags clarity issues rather than rewriting wholesale. Premium adds tone detection and full-sentence rewrites. It does not generate first drafts; its value is ensuring whatever you wrote is clean and appropriately toned before it ships.
The practical division: Notion AI for creation and transformation, Grammarly for correction and consistency. A product manager might use Notion AI to draft a spec, then rely on Grammarly everywhere else — emails, messages, documents outside Notion. If your writing lives primarily in Notion and you want drafting help, Notion AI suffices; if your writing scatters across many tools and needs polish more than generation, Grammarly is the better spend.
