Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.
