Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.B-tier. Still early. Manus is more flexible for less money.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
