Kai's verdictA-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.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
