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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for builders. The right primitives. What Kai is built on under the hood.
