Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
