| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | S-tier for text-in-image. Use this for posters, Midjourney for art. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
