Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Niche but beloved. If you've outgrown Notion, try this.
