Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
