| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Still early. Manus is more flexible for less money. |
