Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.
