| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for academic research. Nothing else comes close for systematic reviews. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. | B-tier. Solid product but crowded market. Try it if Notion AI feels too generic. |
