Kai's verdictB-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.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
