Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for speed. When latency is the product, start here.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
