Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.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.S-tier for model-shopping. I use this for every prototype before committing.
