Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Still early. Manus is more flexible for less money.S-tier for speed. When latency is the product, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
