Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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 teachers. If you teach K-12, start here this week.
