Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-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.
