Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. S-tier if you self-host. The reason open-source image gen matters.
