Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
