Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for model-shopping. I use this for every prototype before committing.S-tier for solo + free. The best free option, hands down.
