Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. Market leader with reason. Start here for serious video.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.
