Dia
AI-first macOS browser from The Browser Company (makers of Arc) with a built-in chat assistant, Skills, and work-tool synthesis
Dia is an AI-first web browser from The Browser Company, the team behind Arc, now owned by Atlassian after a reported $610M acquisition in October 2025. It runs only on macOS 14+ with Apple Silicon. The free tier caps AI chat and Skills usage; Dia Pro is a reported $20/month for unlimited AI access. Best for Mac users who want AI woven directly into browsing.

What is Dia?
Dia is an AI-first web browser for macOS built by The Browser Company, the studio behind the Arc browser. Instead of treating AI as an add-on extension, Dia builds a chat assistant directly into the browsing surface: it reads the page you are on, reasons across your open tabs, and answers questions in a sidebar without pushing you into a separate app. On top of chat, Dia adds “Skills” — reusable, customizable AI shortcuts for tasks you repeat — and a Morning Brief that surfaces your calendar, inbox, and key links when you launch it. It runs only on macOS 14 or later with Apple Silicon (M1 or newer); there is no Intel Mac build, and Windows has remained waitlist-only.
Since Atlassian acquired The Browser Company in October 2025 in a reported ~$610M deal, Dia has leaned into enterprise work. Recent positioning emphasizes synthesis reports that aggregate Slack, Notion, Calendar, and Google Workspace, plus integrations that surface GitHub and Notion in the tab bar and meeting pages that open with agendas attached. Pricing follows a two-tier model: a free tier with frequency caps on AI chat and Skills, and Dia Pro — reported at $20/month — which removes those limits. Notably, Dia’s own pricing page is not publicly available, so the Pro figure comes from press coverage rather than the company’s site, and the exact free-tier caps were never officially disclosed. Arc, the company’s earlier browser, is now in maintenance mode receiving security patches only.
Who is it for?
Dia targets Mac users who already live in the browser and want AI woven into it rather than accessed through a separate tab or chatbot. The free tier suits people who reach for AI a few times a week, while Dia Pro (reported $20/month) makes sense for anyone leaning on the chat assistant and Skills daily. Because it is macOS- and Apple-Silicon-only, it is not an option for Windows, Linux, or Intel Mac users today. Compared with browser-agnostic assistants like Perplexity or ChatGPT, Dia’s advantage is tight page-and-tab context; its trade-off is platform lock-in and post-acquisition roadmap uncertainty.
- Mac-based knowledge workers who want AI to summarize pages, answer questions across tabs, and draft from what is already open.
- Teams inside the Atlassian and wider SaaS ecosystem who benefit from synthesis across Slack, Notion, Calendar, and Google Workspace.
- Former Arc users looking for The Browser Company’s current, actively developed browser now that Arc is in maintenance mode.
- Light AI users who want a free, native browser assistant and only upgrade to Pro if they hit the usage caps.

| Free tier is usable for light AI users making only a few queries per week | Free-tier usage caps were never officially published, so limits are unpredictable |

How much does Dia Pro cost?
Dia Pro is reported at $20/month based on press coverage. Dia's own pricing page is not publicly available, so treat the figure as press-sourced. The company has hinted at future tiers at different price points.
