Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.
