Dia

What is Dia?

Dia is an AI-enhanced web browser built by The Browser Company of New York. The vendor describes it as more than a browser, with a built-in assistant that can answer questions across your open tabs and gather information from tools such as Slack, Notion, Teams and Google Workspace.

Key capabilities of Dia

• Chat with your tabs: ask questions across open pages.
• Morning Brief: calendar, inbox and key links at the start of the day.
• Profiles: separate work, freelance and personal tabs, logins and AI.
• Better Meetings: meeting pages and notes opened with a countdown.
• Splits and Decks: side-by-side views and slides generated from your context.
• Privacy controls: toggles for trackers, ads, memory and personalized chats.

How Dia works

Dia runs as a full browser. The assistant reads the context of your tabs and connected apps to answer questions, summarize pages and help with writing. You control memory and personalization through settings. The vendor says data is not sold or used to build ad profiles, and Sync is end-to-end encrypted.

Who uses Dia?

Knowledge workers who spend their day in the browser and want an assistant that sees what they are working on. Dia for Work adds SSO and admin tools for organizations.

Dia pricing

Dia can be downloaded for free. The vendor does not list pricing for Dia for Work.
