| Kai's verdict | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | 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. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. |
