Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Bet on this one — the Sparkpage format is genuinely new.
