Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
