Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Bet on this one — the Sparkpage format is genuinely new.
