Comet, Perplexity's new browser... and it's absolutely killer.

Meet Comet, Perplexity’s new AI browser. It summarizes pages, autofills forms, compares prices, and organizes tabs automatically. See why it’s a killer app.

Introduction

For the last 20 years, browsers have been passive windows. You open Chrome or Safari, and you do all the scrolling, clicking, and reading. But imagine if your browser was an active participant—a smart assistant that could read over your shoulder and say, "I see you're looking for a laptop; here's a comparison table of the three you just viewed," or "I'll fill out this checkout form while you grab a coffee."​

That is the promise of Comet, the new AI-native browser from Perplexity. It’s not just a search engine with a wrapper; it’s a fundamental rethink of how we interact with the web. Instead of you browsing the web, Comet browses it for you. Whether you are a researcher drowning in tabs or a shopper hunting for the best deal, this tool claims to be the "killer app" of 2025.​

What Is Comet? The "Agentic" Browser Revolution

Comet is built on the idea of "Agentic Browsing." This means it has an integrated AI agent that can "see" what’s on your screen and take actions.​

Unlike traditional chatbots that live in a sidebar and can only read text you copy-paste, Comet has full context awareness. It knows you have 10 tabs open about "hiking boots," and it can synthesize information across all of them instantly. It is built on Chromium, so all your favorite extensions still work, but it adds a layer of intelligence that turns every webpage into a structured database.​​

Feature 1: The 2-Second Summary Engine

We’ve all been there: opening a recipe blog and scrolling past 10 paragraphs of someone’s childhood memories just to find the ingredients. Comet kills this pain instantly.​

With a single click or prompt, Comet reads the page and extracts exactly what you need—whether it’s the recipe, the pricing table, or the conclusion of a long academic paper. But it goes further: you can ask it questions about the page. "Does this review mention battery life?" or "What are the pros and cons listed here?" The answer appears instantly, cited and verified, saving you minutes of skimming per site.​

Feature 2: The "Autopilot" for Forms and Shopping

This is the "killer" feature. Comet isn't just for reading; it’s for doing.​

• Shopping: Tell Comet, "Find the best noise-canceling headphones under $300 and compare shipping times from Amazon, Best Buy, and Walmart." It will visit those sites, check stock, finding coupons, and present a side-by-side comparison.​

• Form Filling: Hate typing your address and credit card info for the thousandth time? Comet securely stores your details and can autofill complex forms—even applying for jobs or booking flights—by understanding the context of each field better than standard autofill.​

Feature 3: Unified Research & Organization

If your browser looks like a "tab explosion" disaster zone, Comet is your cleaner.​

It automatically groups related tabs into Collections. If you're planning a trip to Japan, it groups your flight, hotel, and blog tabs together. You can then ask, "What is the total cost of the flights and hotels I have open?" and it will calculate it. It essentially treats your browser history as a knowledge base, allowing you to search for "that article about AI I read last week" using natural language, rather than hunting for a URL.​​

Is It Worth Switching? (Pros & Cons)

Pros:

• Speed: Summaries and comparisons happen in seconds.​

• Action-Oriented: It actually does things (clicks, types) rather than just talking.​

• Privacy: Perplexity emphasizes user control, and many local actions happen on-device.​

• Free Tier: Core features are now free for everyone.​

Cons:

• Habit Breaking: Switching browsers is hard; migrating passwords and bookmarks takes effort (though Comet makes it easy).​

• Complexity: It can feel overwhelming for users who just want a simple window.​

• Accuracy: Like all AI, it can occasionally misread a complex form or site.​
