Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for solo + free. The best free option, hands down.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
