Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
