Dia is a free AI browser for macOS and Windows from The Browser Company that turns scattered tabs, tools, and meetings into an organized, focused workday.
About
Dia is an AI-assisted web browser built by The Browser Company of New York, the team behind the Arc browser. It is designed for people whose work is spread across dozens of tabs, chat threads, documents, and meetings, and who spend too much time hunting for context instead of using it. Dia's core idea is that the browser already holds most of your working context, so its AI can read across your tabs and connected tools to answer questions, summarize projects, and prepare your day.
At a high level, Dia combines a Chromium-based browser with an assistant that sits on top of everything you have open. It offers a Morning Brief with your calendar, inbox, and key links; it can pull information from tools like Slack, Notion, Microsoft Teams, and Google Workspace into shareable reports; and it includes work-oriented features such as profiles, split layouts, meeting preparation, and slide generation. A "Dia for Work" tier adds team administration controls.

Who It's For
Dia suits knowledge workers whose day is spread across many browser tabs and SaaS tools — for example, project managers pulling status from Notion and Slack, developers moving between GitHub pull requests and specs, and freelancers who need clean separation between client and personal contexts. It also fits anyone whose calendar is dominated by meetings, thanks to automatic meeting preparation and remembered split layouts. Teams with compliance needs can consider Dia for Work for SSO and administrative controls.
