Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier in its niche. The only one that actually gets emotion right.S-tier for builders. The right primitives. What Kai is built on under the hood.
