What is Dia?
Dia is a web browser built by The Browser Company of New York, available for macOS and Windows. Alongside standard browsing, it adds AI features that read across your open tabs and connected work tools such as Slack, Notion, Teams, GSuite and GitHub. You can ask it a question once and it answers using that scattered context instead of you searching each tool separately.
In practice, Dia offers a Morning Brief that summarizes your calendar, inbox and key links before the day starts, and can synthesize information from several tools into a report you can share. It also groups tabs into named workspaces, splits the view between a meeting and a document, prepares meeting pages with agendas and notes, and can turn your context into slide decks. Privacy controls let you toggle tracker and ad blocking, memory, and content sharing.
