The New Wave of AI Browsers: Comet, Dia, and the Future of Web Browsing

The core idea: context without copy-pasting

Most people already use AI while browsing, but through an awkward workflow: copy text from a webpage, switch to a chat tab, paste it in, ask a question, switch back. AI-native browsers like Comet (from Perplexity) and Dia (from The Browser Company) eliminate this by giving the assistant direct access to what you already have open.

Ask "compare these two product pages" or "summarize what I've read today" and the assistant already knows what tabs are open and what you have been browsing, without you explaining any of it first.

Comet: search-first AI browsing

Built by Perplexity, Comet leans into its parent company's strength: cited, sourced search results, now built into the browsing experience itself. Its assistant can summarize pages, compare information across tabs, and help complete tasks that span multiple websites, all from a sidebar rather than a separate app.

Dia: chat with your tabs

Dia, from the team behind Arc, takes a similar but distinct approach, emphasizing a clean chat interface that is always aware of your open tabs. Its "skills" feature lets you save repeatable browsing workflows, useful for tasks you do often, like a weekly research routine.

What you actually gain

The practical time savings show up most in three places: summarizing long pages without leaving them, comparing multiple open tabs without manually noting differences, and completing small multi-step tasks (like filling a form using information from another tab) without switching context repeatedly.

What you give up, at least for now

Both browsers are newer than Chrome, meaning smaller extension ecosystems and less battle-tested compatibility with every website's quirks. Trusting an AI assistant with broad visibility into your browsing also raises reasonable privacy questions worth understanding before switching your daily driver.

Should you switch?

If a large part of your day involves research, comparison, or reading across many tabs, trying one of these browsers for a week is a low-risk way to find out if the workflow genuinely saves time for you. If your browsing is mostly straightforward and extension-dependent, the switch may not be worth the adjustment yet.
