Dia Browser

Dia is The Browser Company’s AI browser for Mac and Windows, built around skills, memory and an assistant that understands your tabs and your work.

Overview

Dia arrived after the Arc browser, redesigned from scratch for an AI-first era. Its assistant works across your open tabs, letting you compare, summarize and draft from several pages at once, while skills turn repeated prompts into one-command workflows.

Dia’s memory features can recall pages you have read and personalize responses to your context, all processed with an emphasis on on-device privacy where possible. Video understanding, calendar integration and writing assistance round out a browser designed to feel like a calm, capable workbench rather than a chat window bolted onto Chrome. Skills can encode your own recurring workflows, so repetitive research and writing tasks collapse into single commands. Memory features are designed to be transparent, letting you see and manage what the browser remembers.

Pricing

Dia is free to download and use with core AI features. A paid Dia Pro plan unlocks higher usage limits, premium models and advanced memory features, and the team has signaled evolving subscription tiers as capabilities expand. The free tier covers most daily browsing assistance, and Pro pricing is modest relative to the productivity gains regular users report.

Who Is It For

Dia is for Mac and Windows users who live in the browser and want AI woven into daily research, reading and writing. Students, writers and product teams who liked Arc’s design ethos will feel at home. It also appeals to privacy-minded users, with local processing wherever practical and clear controls over stored context.

FAQ

Is Dia Browser free to use?

Yes, Dia is free for everyday use including core assistance features. Heavy users can subscribe to Pro for larger limits and premium model access.

Does Dia Browser offer an API?

Dia is a consumer browser without a public agent API. Developers looking to embed similar capabilities use model and browser-automation APIs directly.

How does Dia Browser compare to alternatives?

Dia competes on craft and privacy rather than raw agent autonomy, making it delightful for daily browsing and research. Users who need unattended task execution may prefer more agentic browsers, while Dia suits thinking work. Dia is ideal when browsing is where thinking happens; users who need unattended execution across sites should weigh more agentic alternatives.
