About
The Browser Company's AI-native browser — chat with an assistant that has context on your open tabs and browsing history to summarize, compare, and act on what you're viewing.
In-Depth Review
Dia is a browser built by The Browser Company (creators of Arc) around an AI assistant that has direct context on the pages a user has open, rather than requiring copy-paste into a separate chat window.
Core Capabilities
Tab-Aware Chat The assistant can reference currently open tabs by name, summarizing or comparing content across them (e.g. "compare these three product pages") without manual context-passing.
Browsing History Context Can answer questions grounded in a user's own recent browsing history, useful for resurfacing something read earlier without re-searching.
Skills Supports reusable prompt "skills" for repeated tasks (e.g. drafting an email in a particular tone), similar to custom GPTs but scoped to the browser.
Positioning
Part of a wave of AI-native browsers (alongside Perplexity Comet, Opera Neon, ChatGPT Atlas) competing to make the browser itself the AI interface rather than a separate app.
Pricing
Free during beta, invite-based rollout.
