Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. The Deep Research feature is genuinely useful.
