Kai's verdictA-tier for creators training custom looks. B-tier for general use.A-tier. Best for teaching a kid to code in 2026.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
