The browser has always been the center of how we use the internet — whether it’s Chrome, Safari, Firefox, or Edge. But in 2025, a new contender arrived: Comet, an AI-powered browser by Perplexity.
Unlike Chrome or Safari, Comet isn’t just a “window” to the web. It’s an AI agent living inside the browser, ready to work with you in real time. And that’s a big shift.
🌐 What Makes Comet Different from Other Browsers
Most browsers today act like neutral tools. You type, click, search, and navigate — and all the intelligence lives in other apps or search engines.
Comet flips that model upside down. It builds the AI directly into the browser, so you can interact with the web more like talking to an assistant than manually driving a car.
1. Built-In AI Agent (No Extensions Needed)
Unlike Chrome or Firefox, which rely on add-ons or extensions, Comet includes a native AI assistant in its sidebar.
You can ask it to:
- Summarize the page you’re on
- Reference your open tabs using
@tab - Search and act on results (not just show them)

Example: Instead of opening 6 tabs about flight options and comparing them manually, you can ask Comet: “Find the cheapest flight from NYC to Lisbon in December and add it to my calendar.”
The browser does the legwork.
2. Agentic Browsing Instead of Passive Surfing
Traditional browsers only display information. Comet actually acts on information.
- It can execute multi-step tasks like booking, emailing, or scheduling
- It keeps context across tabs
- It responds conversationally, not just with links
This means your browser becomes less of a tool — and more of a partner.
3. Deep Context Awareness
In Chrome, each tab is isolated. Comet is different.
- It “sees” your open tabs
- It uses them to give more accurate answers
- It can combine context from multiple pages
This small change makes complex workflows much faster.
Example: You can open a product spec sheet, a competitor site, and your notes — then ask Comet to “compare these and draft a summary email.”
⚡ How Comet Improves the Browsing Experience
Beyond features, the real question is: does it make things better?
Here’s where Comet stands out:
✅ 1. Fewer Clicks, Faster Actions
No more bouncing between apps or copy-pasting info. Comet can handle:
- Research + comparison
- Email & scheduling
- Project organization
- Shopping & travel booking
This collapses 4–5 steps into a single conversation.
🧭 2. A Seamless Flow Between Search and Action
In Chrome, Safari, or Firefox — search gives you a list of links.
In Comet — search can end in a booked meeting, a drafted email, or an exported note.
The AI isn’t bolted on. It’s baked in.
🔐 3. Built on Chromium (So It’s Familiar)
Unlike new experimental browsers that feel foreign, Comet is built on Chromium, meaning:
- Chrome extensions work
- The interface is familiar
- Migration is easy
So, switching doesn’t feel like starting over.

🛡️ Limitations & Considerations
No AI browser is perfect — and Comet is still evolving.
- Security concerns: Since the AI can act across tabs, prompt-injection and phishing risks are being actively monitored.
- Accuracy gaps: Multi-step tasks can misfire if instructions aren’t clear.
- Adoption curve: Replacing your default browser is still a big ask for most users.
That said, early testers say the time savings outweigh the friction. And security updates are rolling out fast.
🌍 Pricing and Availability
- Initially launched in early access for $200/month (Pro tier)
- Now available to everyone for free (as of October 2025)
- Mac and Windows versions live; mobile coming soon
✨ Final Thoughts: A Glimpse of the Future
Comet represents something bigger than “a new browser.”
It’s an early sign of the next interface shift: from “browsing” to “doing.”
Where Chrome gave us speed, and Firefox gave us control — Comet gives us an AI-powered workflow inside the thing we already use every day.
Whether it will replace Chrome remains to be seen. But one thing is clear: agentic browsing is here, and it’s changing how we use the web.
