Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier in its niche. The only one that actually gets emotion right.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for model-shopping. I use this for every prototype before committing.
