Kai's verdictS-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. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
