Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
