Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
