Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. Niche but beloved. If you've outgrown Notion, try this.
