Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.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.S-tier. If you're on Vercel/shadcn, this is cheating.
