Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Still early. Manus is more flexible for less money.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
