| Kai's verdict | S-tier for text-in-image. Use this for posters, Midjourney for art. | A-tier. Bet on this one — the Sparkpage format is genuinely new. | A-tier in its niche. The only one that actually gets emotion right. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
