Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
