Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
