Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
