Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
