Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
