Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
