About Dia

Dia is a Chromium-style web browser with an AI assistant built into the address bar and sidebar, made by The Browser Company of New York, which Atlassian acquired in 2025. Users can ask questions about the page they are on, reference other open tabs, and connect work apps such as Google Workspace, Slack, Notion, Teams and Atlassian products so the assistant can answer from that context. It runs on macOS and, since October 2026, on Windows.

Best for

  • Asking questions across tabs and connected work apps, summarizing pages and meetings, and organizing many open tabs
  • Morning planning: Use the Morning Brief to review calendar, inbox and key links before starting work.
  • Research across tabs: Ask one question that draws on several open articles or documents.
  • Meeting prep: Open agendas, notes and related docs together with a countdown to the meeting.
  • Reports and slides: Turn gathered context from tabs and apps into a report or deck.
  • Team rollout: Deploy Dia to a company with SSO, MDM policies and AI controls.

Not ideal for

  • Linux users, mobile-first users (no released phone app), and people who want no AI features in their browser

Popular with

  • Knowledge workers
  • Teams using Google Workspace or Atlassian tools
  • Researchers
  • Students
