Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier if you already pay Gemini. B-tier standalone.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
