Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
