Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
