Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for sales teams. B-tier for solo users.
