Kai's verdictS-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.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
