| 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 Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | B-tier. Still early. Manus is more flexible for less money. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. |
