Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
