Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for sales teams. B-tier for solo users.
