Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for speed. When latency is the product, start here.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
