Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier in its category. The first AI music tool I'd actually listen to.S-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.
