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 academic research. Nothing else comes close for systematic reviews.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Still early. Manus is more flexible for less money.
