Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
