Kai's verdictS-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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Still early. Manus is more flexible for less money.
