| Kai's verdict | 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. | B-tier. Solid product but crowded market. Try it if Notion AI feels too generic. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. |
