"Grammarly or Notion AI?" sounds like a question about which writing assistant is better. It usually isn't. It's a question about whether the job is the sentences, or the page they already live on. Both can rewrite text. They don't put the same thing back in your hands afterwards.
This is a short version of our guide, Grammarly vs Notion AI. It only uses the rankings we've already published. There are no prices here, on purpose. Check each vendor's pricing page before you pay.
The short version
On our Best for Writing list the order is Claude, then ChatGPT, then Gemini, then Grammarly, then Notion AI.
- "The sentences exist, and I want tone, clarity, and grammar." Use Grammarly.
- "The page is already in Notion, and I want it summarized, rewritten, or cleaned up in place." Use Notion AI.
- "The draft has to sound like a person." Use Claude (not this pair).
- "A generalist rewrite I will edit." Use ChatGPT (not this pair).
- "The file is already in Gmail or Docs." Use Gemini (not this pair).
Grammarly: when the draft exists
Grammarly is fourth. The job is an editor for clarity, tone, and grammar on text you already wrote. Generating the piece from scratch is not why it earns a spot. Stay when the words exist and the last pass is the job.
Leave it when the page is blank, and leave when the job is to clean a messy page in place. An editor is not a notebook cleaner.
Notion AI: when the page is already the system of record
Notion AI is fifth. It is worth it when the document is already in Notion and you want a summary, a rewrite, or a messy page cleaned up without exporting it. It is a poor standalone writing tool.
Leave it when the sentences exist and you want tone, clarity, and grammar checked. If you export the page and then ask Notion AI to be your grammar checker, you have left the reason for the rank.
