Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
