Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
