Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
