The AI browser that reads between your tabs
Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.

A multiplayer browser where your team shares one workspace
Build views with your favorite apps so the whole team works from the same set of tabs, files, and sites instead of scattered windows.
Highlight text, select image areas, point at video timestamps, or mark regions inside a site and leave a threaded comment right there.
Scrub backward through the history of apps, files, and conversations, then jump back into any moment and keep working in the app.
The assistant reads your open tabs and learns from team conversations, so it can answer questions only a coworker could previously handle.
