Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
