Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-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.
