Kai's verdict	B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for model-shopping. I use this for every prototype before committing.
