Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for speed. When latency is the product, start here.B-tier. Still early. Manus is more flexible for less money.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
