Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for open-source model APIs. The default in this space.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
