Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
