The Browser Company's AI browser — chat with your tabs

Overview

Dia is the AI-first browser from the makers of Arc: a chat bar that sees your open tabs, writes with your context, summarizes and compares pages, and personalizes to your browsing style. Arc's successor built around AI rather than retrofitted with it.

Features

Chat that sees your open tabs

Write-anywhere with page context

Compare and summarize across tabs

Personalized skills and shortcuts

Imports everything from Chrome/Arc

macOS (more platforms coming)

How to Get Started

Download from diabrowser.com (macOS), import from Chrome or Arc, and use the chat bar on any page — ask across multiple tabs by @-mentioning them.

FAQ

What happened to Arc?

The Browser Company shifted focus to Dia as the AI-native future; Arc remains available but Dia gets the innovation.

Dia vs Comet?

Comet leans research-agent (citations, multi-source synthesis); Dia leans personal writing-and-context companion. Try both — they feel genuinely different.

Is it free?

Yes currently — premium tiers may gate heavier AI usage later.
