Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier in its niche. The only one that actually gets emotion right.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.
