The honest brief

Lex

Frontier models inside a focused Google-Docs-style writing surface — pick premium models in the doc, not a sidebar.

  • Clean, distraction-free doc editor
  • Premium model choice (Claude/GPT)
  • Real-time collaboration + versions
  • AI feedback and rewriting inline
  • Web-only
  • Premium models behind Pro tier
  • Narrow long-form focus

Notion AI

Native to the workspace where your notes already live; Enterprise Search reaches into Slack, Drive, and GitHub.

  • Built into the Notion workspace
  • Q&A across pages + connected apps
  • AI meeting notes and custom agents
  • Multi-model picker
  • Value depends on living in Notion
  • Add-on pricing on top of Notion seats
  • Search quality varies by workspace hygiene
