Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
