Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Best for teaching a kid to code in 2026.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
