Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for open-source model APIs. The default in this space.
