Kai's verdictA-tier for sales teams. B-tier for solo users.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
