Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for designer-led sites. S-tier if animations matter.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.
