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.

Your new tab becomes a keyboard-first workspace — tasks, tabs, focus, notes and an AI agent.
One list, four ways to see it. Switch between list, board, table, and calendar with number keys 1–4 without moving a single task.
Save a research trail — a launch, a bug hunt, a reading list — as a tab session and restore the whole set with one click instead of rebuilding bookmarks.
Tasks live in Inbox, Today, Next week, project lists, and personal lists. Details stay folded inside each task until you open it, keeping the list short.
A quiet Pomodoro-style focus timer and a keyboard-first command palette keep deep work moving without reaching for the mouse.
