Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.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.
