Comet AI Browser: Features, Uses & How It’s Changing Web Browsing

IT Updated on : November 5, 2025

Imagine stepping into a smart study room where your browser is not just a window to the web, but your personal assistant that helps you research, summarize, schedule, shop, and more—all from one interface. This is what motivated Perplexity AI to develop the Comet AI Browser and is making big headlines in 2025, described as a next-generation “agentic” browser.

In this blog, let’s discuss what Comet is, how it works, its key features, and much more.

What is the Comet AI Browser?

Perplexity describes it as “the browser that works for you.”

In July 2025, Perplexity AI launched the Comet AI Browser to limited-access users, a web browser that re-imagines the web browsing experience. It is the first AI-native browser that is based on agentic browsing globally. It’s not like traditional browsers, where AI comes as clunky add-ons; Comet’s assistant is integrated into every action.

The “agentic” model means Comet will not only suggest links, but will also take actions, navigate, summarize, collate data, and complete user-initiated tasks across tabs, apps, and web workflows. Comet utilizes Perplexity’s own AI search engine, built-in agentic features (e.g., an assistant side panel that interacts with web pages), and offers task automation capabilities.

Essentially, Comet is not just a browser – it is a continually evolving productivity hub for professionals, knowledge-workers, and all those who want more from their browsing experience.

Comet AI Browser Pricing and Plans

As of Oct 2025, Perplexity makes the Comet AI browser a freemium tool accessible globally. In the initial phase, it usually costs you $200/month. Here’s the detailed price and plan breakdown for better understanding:

Any hidden costs?

The company does say that they are committed to transparency with this statement on their official site: “There are no hidden fees … you always know what you’re paying. “However, advanced features may require upgrading, and using some integrations (email/calendar) might involve permissions or associated accounts.

Key Features of Comet AI Browser by Perplexity

1. Agentic AI Sidebar: The Comet Assistant is deeply integrated and allows you to control tabs, schedule meetings, email, book reservations, summarize web content, extract data into spreadsheets, and automate tasks through natural language commands.

Imagine this, the Comet Assistant can pull all prices for products listed in an article and autofill a spreadsheet or summarize the important points from a YouTube video directly.

2. Multi-Step Task Automation: The browser is capable of automating tasks, automatically filling out forms, pulling contextual information across tabs, and even interacting with web apps for third-party applications and content editors, such as Gmail and Google Calendar.

3. Conversational & Contextual Search: Rather than just returning links, Comet’s search function engages in contextual, source-cited conversations, based on your open tabs and intent.

4. Email and Calendar Integration: Comet’s full read/write access enables it to manage your inbox (e.g., summarize chains, identify important replies, etc.) and schedule or book meetings with privacy safeguards in place.

5. File & Content Analysis: Higher-tier subscribers can upload files, generate analysis, and create images or videos using the latest AI models.

6. Cross-Device, Chromium-Based: Comet works with existing Chrome extensions (i.e., ability to import bookmarks and logins) and is built atop a Chromium engine for stability and performance.

Comet AI Browser vs. Other AI Browsers

Here is a quick comparison of Comet against other options, such as ChatGPT and Dia Browser (from The Browser Company).

Feature	Comet AI Browser	ChatGPT Atlas (or equivalent)	Dia Browser
Agentic Browser Core	Yes (built with AI-first architecture)	Yes (AI-native browser reported)	Early stage (AI-first design)
AI Assistant Integration	Built-in sidebar assistant	Built-in chat/assistant	Chat interface; agentic features emerging
Workflow Automation	Advanced (tab summarisation, crosstab actions)	Basic features reported	Early-stage automation
Platform Support (2025)	Mac & Windows available; mobile rolling out	Web first; full platforms unclear	Mac (and other platforms planned)
Pricing (Core Access)	Free tier available for all; premium tiers for advanced	Free/basic tier reported; paid for full features	Free tier + subscription (e.g., $20/month)
Advanced AI Model Access	Paid tiers for full agentic features	Paid tiers expected	Paid access required for full functionality

What sets Comet apart?

• Its agentic features: it’s more than browsing – it’s taking actions. The AI can navigate, summarize, and manage tabs.
• Its focus on workflow automation: Spaces, tabs grouped by projects, and cross-context understanding. All of this is articulated in their “Ways to Use” page.
• It targets the “thinking worker,” not just the “web surfer”.

How Does Comet AI Browser Work?

Here’s a step-by-step look at how you can use Comet:

1. Install Comet & Set Up – Download the browser, import your bookmarks, and set it as your default browser if you wish.
2. Launch a Browsing Session – Open a new tab. As you browse, the AI Assistant remains accessible via a sidebar.
3. Use the Assistant – For example, if you navigate to an article, you may ask: “Summarise this page,” “Summarise the information about X,” “What are the main points about Y?” The assistant will create text based on the page for you.
4. Automate Tasks – You might ask the assistant, “Can you schedule a meeting about this topic next week?” or “Can you find the best price on office chairs for me? The assistant will help with its integration.
5. Workspace and Tab Management – Comet employs a “workspace” model, allowing you to group tabs into a project, have the assistant highlight essential tabs, summarize, or close unrelated tabs. This is different than the model of typical browsers, where each tab exists separately.

As the official site states, “Discover everything that can be delegated, from wrangling inboxes to ordering groceries, staying on top of finances to planning vacations.”

Platform Availability and System Requirements

Perplexity offers the Comet AI browser, which is a Chromium-based web browser for the Windows and macOS operating systems (with an Android version available on pre-order and an iOS version in development).

The browser is available for free globally, though some premium AI features require a paid subscription.

Platform Availability

• Windows: Available (Windows 10 build 1903+ or Windows 11).
• macOS: Available (macOS 12 Monterey or later with Apple Silicon M1+ or Intel Core i5 2017 or newer).
• Android: Available for pre-order on the Google Play Store (providing full mobile feature set expected by Q4 2025).
• iOS: Under development.
• Linux: Not currently available.

System Requirements

The browser performs best on Windows 11 or macOS 13 Ventura, an Intel Core i7 2019 / equivalent / Apple M2 processor, 16GB of RAM, 1GB of storage, and a connection speed of 25+ Mbps. For full use of all AI features, a stable internet connection is required. The browser can be downloaded from the official Perplexity website.

Strong relationships are being built with telecoms (e.g., Airtel in India) and device makers to take advantage for bundling.

How to Download and Set Up Comet Browser?

• Visit the official site and click Download Comet.
• Install the browser for your OS (Windows/macOS/Android).
• On first launch, import your bookmarks from your previous browser.
• Optionally set Comet as your default browser via Settings → Default browser.
• For best use, allow the AI assistant to access tabs and optionally email/calendar (if you want automation features). Be mindful of the permissions.
• Explore workspaces, the sidebar assistant, and ask your first question: “Summarise this page” or “Find me top deals on X”.

The Impact of Comet AI Browser on Productivity

A researcher might have dozens of pages on one subject open, and prompt Comet, “What are the three key themes that are common across these pages?” The assistant would summarize the information for them and extract actionable points, resulting in significant time savings from reading material.

Think how easy it will become for a business owner who can draft an email response, analyze relevant documents from a meeting, and even build a website – all by just using the Comet AI browser by Perplexity.

The move from passive browsing → active productivity is driving interest: “The browser that works for you.”

Limitations:

• Can’t carry out backend actions (e.g., API calls, tagging tickets, or marking as done).
• No granular admin workflow control (unlike a full business AI system).
• Integration is limited to what a human could do through the page, not controlled process automation.

Comet is leading, although it faces rising competition from OpenAI, Google’s Gemini, and startups like Dia. Competition is driving browser innovation in a broader industry context, much more frequently than before.

Comet AI Browser Issues, Fixes & Troubleshooting Guide

Even the most advanced browsers can encounter issues. Here are quick solutions to common problems you may face while using Comet AI Browser:

1. Installation Issues:

• On Mac, if you see “Comet is damaged and can’t be opened,” open Terminal and run xattr -cr /Applications/Comet.app
• On Windows, if blocked by security warnings, click “More info” then “Run anyway”, or unblock the installer in properties.

2. Slow or Failed Downloads:

Ensure your internet connection is stable, pause other downloads, try disabling VPN temporarily, or use a wired internet connection.

3. AI Assistant Not Responding:

Refresh the page, close and reopen the AI sidebar, check your internet connection, or switch to a different AI model from settings.

4. Rate Limit Exceeded Error:

Free users should wait for the daily limit reset, while Pro users should contact support. Temporarily switching to a different AI model can help.

5. Browser Running Slow or High CPU Usage:

Close unused tabs, disable unnecessary extensions, clear browser cache, and update to the latest Comet version. Use Task Manager (Shift+Esc) inside Comet to identify resource-heavy tabs.

6. Pages Not Loading or Loading Slowly:

Perform a hard refresh (Cmd/Ctrl + Shift + R), clear browsing data, disable heavy extensions, and check your internet connection or DNS settings.

7. Voice Mode Issues:

Ensure microphone permissions are enabled in system settings, select the correct microphone in Comet’s AI settings, and test if the mic works in other apps.

8. Update Problems:

If updates fail to install, manually download the latest installer from the official website and run it as an administrator on Windows or replace the app on Mac.

9. Lost Data (Bookmarks, Passwords, AI Conversations):

Check if syncing is enabled, attempt import from backups, and use Comet’s export/import features to recover lost information.
