Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
