Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
