Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-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 in the agent category. The first one I'd give to a non-technical friend.
