Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. Bet on this one — the Sparkpage format is genuinely new.
