Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for designers. The only one that takes vectors seriously.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
