Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
