Kai's verdict	B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.	S-tier for open-source model APIs. The default in this space.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
