Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for open-source model APIs. The default in this space.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
