Looking for something other than Grammarly (by Superhuman) (Free plan; Pro $12 USD, billing period: see site)? These are the alternatives from my curated list. None of these is a dedicated grammar checker, but general AI assistants and Notion AI can rewrite and proofread text you paste in.
- Claude: Strong at long documents, careful reasoning, and writing.
Free plan; Pro $20/mo ($17/mo annual) 
Notion AI: AI writing and search inside Notion workspaces.
Free plan (AI trial); full AI on Business $20/member/mo
Why look past Grammarly?
Grammarly (now part of Superhuman) is great at catching mistakes while you type. People look for something else when they want help writing the draft itself, not just fixing it.
Claude and ChatGPT can rewrite a paragraph, change the tone or tighten an email you paste in. If your writing already lives in Notion, Notion AI can edit it in place.
A simple setup that works for a lot of people: write or draft with a chatbot, then let Grammarly’s free plan catch the small stuff. My workspace has a cover letter workflow that does exactly this.
How to choose
