Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for builders. The right primitives. What Kai is built on under the hood.
