Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
