## Overview

Dia is a Chromium-style web browser with an AI assistant built into the address bar and sidebar, made by The Browser Company of New York, which Atlassian acquired in 2025. Users can ask questions about the page they are on, reference other open tabs, and connect work apps such as Google Workspace, Slack, Notion, Teams and Atlassian products so the assistant can answer from that context. It runs on macOS and, since October 2026, on Windows.

## FAQ

**Is Dia free?**

Dia is free to download and use. The free tier caps AI chat and Skills usage, and a Dia Pro plan at $20 per month raises those limits. The company has not published exact free-tier limits.

**Is Dia available on Windows?**

Yes. The Windows version had its initial release (v1.0) on October 6, 2026, and the site offers a Windows download. Mac remains the more mature version.

**Who owns Dia?**

Dia is built by The Browser Company of New York. Atlassian announced the acquisition on September 4, 2025, and reported sources put the price at $610 million in cash.

**Does Dia have a mobile app?**

No publicly released iOS or Android app was found on the official site.

**How does Dia handle privacy?**

The company says data is never sold or used for ad profiles, Sync is end-to-end encrypted, and users can opt out of sharing content to improve Dia. Dia for Work also lists a SOC 2 Type II examination for calendar year 2025.

**What happened to the Arc browser?**

The Browser Company shifted its focus to Dia and sunset Arc, which no longer receives active development but still gets Chromium security updates. Dia has been importing Arc-style features such as pinned tabs.
