Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
