Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for teachers. If you teach K-12, start here this week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
