Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
