Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
