Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for solo + free. The best free option, hands down.S-tier for speed. When latency is the product, start here.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
