Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.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.S-tier for model-shopping. I use this for every prototype before committing.
