Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.A-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
