Dia Browser

The AI browser that reads between your tabs

Morning Brief

Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.

Context-aware answers across tabs and apps

Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.

Decks and reports from scattered context

Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.

Live Work tab bar

Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.

Strengths & Pros

+AI is built into the browser's core workflow rather than added as a sidebar
+Context spans tabs, email, calendars and connected work tools for genuinely useful answers
+Outputs are artifacts — reports and slide decks — not just chat responses
+Explicit, user-facing privacy toggles plus end-to-end encrypted sync
