Dia is a web browser for people who spend their working day across many tabs, tools and meetings. It is available for macOS and Windows, and the page describes it as a browser built to make the workday easier to get through.

The browser can gather context from the places where work happens. It pulls work tools such as GitHub and Notion into the tab bar, so one click opens the right pull request, spec or draft. Tabs can be grouped and named, such as "Design Review" or "Q2 Planning", so the workspace is easier to scan.

Dia also works across your tools. Its Morning Brief lays out your calendar, inbox and key links before the day starts. You can ask Dia a question and it searches across your tabs and connected tools, including Slack, Notion, Teams and Google Workspace, and answers from that material. It can also turn scattered notes into a report, or into slides you can present.

For meetings, Dia opens the relevant meeting page, agenda, notes and related documents when a call starts, with a countdown so you join on time. Split views let you see a meeting on one side and a document on the other, and Dia remembers the layout you use for recurring meetings or focus time.

Separate profiles keep work, freelance and personal life apart, each with its own tabs, logins and AI context, and you can switch between them quickly.

The page says you control whether Dia remembers your preferences and which tools connect to it. It says your data is never sold or used to build ad profiles, and that Sync data is end-to-end encrypted. Settings for blocking trackers and ads are listed on the page. Dia for Work adds single sign-on and admin tools for teams.

The page does not state a price. Dia can be downloaded for free, and it is aimed at individual workers as well as teams.
