Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for academic research. Nothing else comes close for systematic reviews.
