Perplexity Comet Browser Review: What It Is, How It Works, and Will It Beat Chrome

For the past few months, I've been using the Comet browser by Perplexity AI. I didn't use it very often at first. When it was launched, I got an invite to join Perplexity AI and to try the Comet browser. I started using it around the end of July and used it for a few weeks. But honestly, I didn't find it that good back then, so I stopped using it. For months, I didn't even open it again.

Now, after the full launch in October, I've been seeing a lot of ads and videos about it. Many people are saying it's performing really well. So, I decided to try it again. And this time, I feel it's much better than before. The experience is smoother, faster, and more useful. Earlier, it was mostly like sending simple emails and tasks, but now it's way more capable. I'll share everything about my new experience in this post.

While promoting the Perplexity Comet browser, they claim that it's not just another normal browser with a few buttons. They say it's built differently from the core. They made a fundamental change in how a browser should work, so your interaction becomes much smarter and smoother.

And honestly, I can feel that difference now. Compared to before, the app feels much improved. It's really intelligent and can actually perform tasks while you stay hands-free. It's a browser made for agentic search by Perplexity AI. It means it understands your main goal and then uses a chain of actions or prompts to complete the task automatically.

Instead of just showing you an answer like a normal search engine, it goes ahead and does the task for you, then gives you the final result. That's a big shift in how browsers work.

I'm going to cover everything: what Comet can do, whether it's really useful, if it's safe and legit, and how you can use it.

What is the Perplexity Comet Browser?

So, what is the Perplexity browser, exactly? In simple words, Perplexity Comet is a free web browser created by the AI search company Perplexity.

Perplexity AI's Comet browser is built on Chromium, which is an open-source project. Chromium is the base that powers many popular browsers like Google Chrome, Microsoft Edge, Brave, and several others. This is a great thing because it means Comet supports all the extensions that Chrome or Edge supports.

When I installed Comet, it automatically imported everything from my Chrome. For example, all my passwords, bookmarks, browsing history, and saved data were moved in one click. That made it feel like I was instantly using Chrome inside Comet.

But still, I wouldn't say it's just a copy of Chrome. The main highlight of Comet, as Perplexity AI promotes it, is its AI experience. You don't just browse or search on Google; you have an intelligent assistant right beside you that can actually help you get things done.

This assistant isn't limited like many other AI models that stop halfway. If your internet connection is fine, it can fully complete a task on your behalf. It's smart, responsive, and feels like a real digital helper inside your browser.

Because it's built on Chromium, users switching from Chrome will find it easy to adapt. And honestly, this could become a strong alternative to Chrome. Of course, Google will probably introduce similar features soon, especially with Gemini integration, but for now, Comet feels like the first serious step toward a true AI-powered browser experience.

What Comet Can Actually Do (Agentic Search)

The main power behind the Perplexity Comet browser is something called agentic search. This is what makes it different from normal browsers and regular AI tools.

So, what does agentic search really mean? Imagine a normal AI assistant or chatbot. You ask a question, and it gives you an answer. That's reactive. But an AI agent is proactive. You tell it what you want to achieve, and it figures out the steps to get it done on its own.

That's exactly what Comet does. It doesn't just search or show answers. It takes action for you. It can browse the web, click buttons, fill forms, and move between sites to complete a task automatically.

Examples of Comet Agentic Browsing Use Cases

There are almost unlimited use cases for the Comet agentic browser. I haven't even explored most of them yet. I'm just sharing a few that I've tried myself.

If you import your browsing history from Chrome to Comet, it lets you get your manual tasks done automatically by giving you smart suggestions.

That's one of the best things about it. It doesn't just copy your history; it understands your habits. Based on that, it recommends tasks that you often repeat, helping you save time through automation.

Here are some of the tasks it found from my browsing history and suggested to automate.

Task Automation

• Travel Planning: The other day, I was spending hours on Chrome trying to find a flight from Delhi to Bangalore. I was also looking for hotels in Bangalore near the city centre because I had to attend an event. I wanted something affordable, with good reviews, and close to everything on Google Maps. I noticed that the same activity was imported into Comet. Comet suggested trying with Perplexity's assistant. I clicked on it, and it did everything automatically. All I had to do was enter my card details to confirm the booking. The entire process was completed automatically.

• Online Shopping: I asked the Perplexity Assistant to find the top five DSLR cameras from any brand, like Sony, Nikon, or Canon, under $1,000. After a few minutes, it showed me the exact camera that matched all my needs. It really was one of the best options out there. Normally, this kind of research would take me hours, but Comet did it in just minutes. All I had to do was open the Amazon link and buy it.

• Job Applications: On Reddit, one user shared that he successfully used the Comet browser to apply for more than 100 jobs on LinkedIn using the Easy Apply feature. All you need to do is log in to your LinkedIn account inside the Comet browser and tell it to start applying. Comet will take care of everything automatically.

Productivity and Organisation

• Email Management: You can connect Comet to your Gmail account, just like I did. Once it's connected, it can help you manage all your emails. If there are messages you haven't replied to or missed, you can ask Comet to open them and show you. It can also respond to emails, delete unimportant ones, and even unsubscribe you from unwanted newsletters. Basically, it can do almost everything you would normally do in your inbox.

• Calender Management: Comet can also handle your calendar. Once you connect your Google Calendar, it checks your schedule, finds free time slots, and can even send invites to others for meetings.
• Tab Management: If you open too many tabs and your browser becomes slow, Comet can clean up the unnecessary ones. It can close distracting tabs like social media sites and keep only the important ones active. One more cool thing I noticed is that you can ask it to find ten YouTube videos on any topic, summarise them, and put all the summaries into a new Google Doc. It actually opens a new tab and creates that document for you.

Research and Reports

• Deep Research: I often use Perplexity AI for deep research, and I've found that using the Perplexity Assistant inside the Comet browser makes it even better. It's perfect for finding trending YouTube topics in your niche or researching new ideas for content. If you have kids, it can also help with school projects or assignments by finding the right information and summarising it clearly. You can even use the deep research feature to check the latest news and see what major outlets are covering on any topic. It collects everything in one place and gives you a complete summary, which saves a lot of time.
• Report Generation: I often create SEO reports for my blogs. I just connected my Google Search Console, Analytics, Bing Webmaster Tools, and Clarity accounts, and Comet handles everything. It uses Perplexity's agent to analyse the data and gives me a full report within minutes. It shows which keywords are performing well, how users behave on my site, and what improvements I need to make.

What makes Comet so powerful is that its AI can work inside your logged-in accounts. A normal chatbot can't access your personal emails or your Amazon cart, but Comet's agent can. This gives it the ability to perform real actions and create personalised automation for you.

However, with this great convenience also comes some security concerns, which I'll talk about later.

How to Get and Install the Perplexity Comet Browser

Let me guide you on how to install Comet and start using it. Getting started with the Comet browser is quick and easy. It takes only a few minutes.

1. Go to the official website
Open your current browser and visit the official Comet page at perplexity.ai/comet.

2. Download the installer
Click the big "Download Comet" button. The site will automatically detect your operating system (Windows or macOS) and give you the correct file to download.

3. Install the browser
Once the file is downloaded, open it and follow the simple on-screen instructions to install Comet on your computer.

4. Import your data
During setup, Comet will ask if you want to import your bookmarks, passwords, browsing history, and extensions from your previous browser (like Chrome). It's a good idea to allow this so you can continue where you left off easily.

Is Comet Browser Available for Windows and Mac?

Yes, the Perplexity Comet browser is currently available for desktop users. It supports the following platforms:

• Windows: Windows 10 and Windows 11
• macOS: Mac computers with Apple's M1 chip or newer

A mobile version of Comet is still in development and hasn't been released yet. Once it launches, I will update here. This is one of the main limitations right now for people who want the same browsing experience across all their devices.

Perplexity does have mobile apps for both iOS and Android, but those are designed only for the AI search engine. They don't include the full Comet browser experience yet.

Cost and Value: Is the Comet Browser Free?

Yes, the Comet browser is completely free to download and use.

However, the advanced AI features inside Comet are powered by Perplexity AI, which follows a freemium model. You can think of it like getting a free car, but the premium fuel (the advanced AI) comes in different plans.

• Perplexity Free Plan (Standard): The free plan gives you a limited number of "Pro Searches" each day, usually around five. That's enough for most casual users to explore how Comet works and try its main features.
• Perplexity Pro Plan ($20/month): This plan unlocks the full power of Comet. You get over 300 Pro Searches per day, access to advanced AI models like GPT-4o and Claude 3.5, the ability to upload and analyse unlimited files, and tools for AI image generation. I'm personally using the Pro plan, and it works smoothly with both Comet and the Perplexity Assistant.
• Perplexity Max Plan ($200/month): This is made for heavy users and professionals who need unlimited access to the most advanced models and want early access to new features before public release.

It's a smart business model. Perplexity gives away the browser for free so people can experience its AI in action. They are using the free browser to attract users for the Pro subscriptions. With the free plan, they provide enough to show its real value and encourage upgrades over time.

Is Comet Browser Safe and Private?

When a browser's AI can access your email and calendar, privacy and safety become very important. This is the first thing I checked before logging into my different application accounts.

Official Security and Privacy Policies

Perplexity AI has a strong security foundation. The company is SOC 2 Type II certified, which means it follows strict standards for data security and privacy. According to its privacy policy, Perplexity does not sell user data.

• If you're a Pro user like me, you can choose in the settings to opt out of having your search data used for AI training.
• For Enterprise and API users, Perplexity has a zero-data-retention policy, which means none of your data is stored or used for model training.

The Risk with Agentic AI

Even with these strong policies, agentic AI still has some new risks. Security researchers found that earlier versions of Comet had a weakness called indirect prompt injection. In simple terms, this means a malicious website could try to trick the AI into performing actions you didn't ask for, like clicking unsafe links or sharing private information.

The Verdict on Safety

Comet is built by a trusted company and follows industry-standard security measures. For regular browsing, it's as safe as any Chromium-based browser like Chrome or Edge. But, since agentic AI is still new, it's best to be careful. Avoid using the AI assistant for highly sensitive tasks such as online banking or entering confidential data on unknown websites until the technology becomes more mature.

Perplexity Comet vs. Google Chrome

For many years, Google Chrome has been the undisputed king of web browsers. Even Microsoft Edge couldn't beat it, despite having a large user base. So, the big question is: can Perplexity really compete with Chrome? How good is the Perplexity AI browser Comet vs Chrome?

Now, it’s important to note that Google owns Chrome, and Google is investing billions of dollars in AI. They've also launched Project Mariner, which brings agentic AI directly into Chrome through Gemini, Google's own AI assistant. This is going to make Chrome even more powerful in the future.

In fact, some users in the United States already have access to Gemini inside Chrome as an assistant. Google plans to add more features and eventually roll them out globally.

But for now, we can still compare the current version of Perplexity's Comet browser with Google Chrome. So, here's a direct comparison between the two.

• AI Integration: This is the biggest difference between the two. Comet's AI is proactive and deeply built into the browser. It can control tabs, perform actions, and complete tasks for you automatically. Chrome’s AI, Gemini, works more like a chatbot. It stays in a sidebar, can summarise web pages, and answer questions, but it can’t take actions across multiple websites like Comet can.
• Core Purpose: Comet is built mainly for productivity, research, and automation. It focuses on helping you do things faster. Chrome, on the other hand, is a general-purpose browser designed to connect users to Google's ecosystem, which is largely powered by ads.
• User Experience: Comet has a clean and minimal design that keeps the AI front and centre. Chrome is familiar to billions of users but can feel cluttered, especially when many extensions and Google services are active.
• Privacy and Business Model: Comet’s business model is based on paid AI subscriptions, not ads. That means its focus is on earning user trust by keeping your data private. Chrome’s business model depends on collecting user data to fuel its advertising system, so privacy is not its strongest area.
• Ecosystem and Sync: This is where Chrome still leads. It offers smooth and reliable syncing of bookmarks, history, passwords, and tabs across desktop, mobile, and tablets. Comet, for now, does not have a mobile version and doesn’t support cross-device syncing, which is a drawback for users who switch between devices often.

Comparison Table: Perplexity Comet vs. Google Chrome

Pros and Cons of Switching to Perplexity Comet

Understanding the Perplexity AI Assistant

The good thing about the Comet browser is that it comes from the Perplexity AI Assistant. Let's look at what powers it.

Who created the Perplexity AI Assistant?

The assistant was built by the Perplexity AI team itself. It's not a third-party tool added later. It's an important core part of their product.

Which AI models does it use?

The assistant doesn't depend on a single model. Instead, it uses several of the world's best large language models (LLMs), depending on your plan and the type of task you're doing.

• Free Plan: Uses Perplexity's own Sonar model, which is based on Meta's Llama 3. It's tuned to give fast and factual answers.
• Pro and Max Plans: Give access to advanced models such as GPT-4 or GPT-5 (OpenAI), Claude Sonnet/Opus 4.1 (Anthropic), and Gemini 2.5 Pro (Google).

This flexible, "model-agnostic" setup is a big advantage because Perplexity can always choose the best-performing AI for each task.

If you want all models in one interface at minimum cost, then I would recommend ChatLLM Abacus AI or Dhruv Rathee's AI Fiesta.

Main Features of the Perplexity AI Assistant

• Multimodal abilities: It can understand text, voice commands, and even images from your phone's camera (through the mobile app). But it's speech to speech-to-text feature on Comet is the worst.
• Context awareness: It remembers what you've been talking about so you can ask follow-up questions and chain multiple commands together to finish a complete task.
• Fact-checking with sources: Perplexity focuses on trust and transparency. It provides answers with citations and links to sources so you can easily check the information yourself.

Integrating Perplexity with Chrome

If you like Perplexity's AI but don't want to stop using Chrome as your main browser, there's good news. You don't have to switch. You can add Perplexity's power directly to Chrome.

Many people ask, "Can I integrate Perplexity AI with my Chrome browser?" The answer is yes. Perplexity offers official Chrome extensions that bring many of its best features right into your browser.

• Perplexity AI Search Extension: This is the easiest way to start. It lets you set Perplexity as your default search engine in Chrome and adds a small toolbar button for quick access to its AI search page.

Perplexity Lens: This is a more advanced tool for power users. It can instantly summarise any webpage you're reading, explain highlighted text using AI, and even create a visual "knowledge graph" that connects ideas and topics as you browse.

Using these extensions gives you the best of both worlds. You can keep the familiar setup and syncing features of Chrome while boosting it with Perplexity's advanced AI search and summarisation abilities.

But it does not mean that you can access Comet's agentic feature on Chrome if you install this extension. If you want to use Perplexity's assistant, then you need to use Comet as your browser.

Comet is NOT DarkComet

There is something called Dark Comet, and it is not the same as Comet. If you see the name Dark Comet online, do not confuse it with Perplexity's Comet browser. Dark Comet is dangerous malware. It is a Remote Access Trojan (RAT) that lets hackers secretly control your computer.

If you find anything called Dark Comet, stay away from it. Do not download it. If you want the real Comet browser, always download it from Perplexity's official site or use an invite link that redirects to perplexity.ai. That is the safest way.

If you use the link in this post, make sure the final page goes to perplexity.ai. I only share links that are safe, but double-check the address before you download. Remember, Dark Comet is a virus used to hack computers. Comet by Perplexity AI is a browser. They are totally different.

Is Comet the Browser of the Future?

The Perplexity Comet browser proved what future browsing will look like. It’s not just another browser; it feels like a smart assistant working to make you more productive. For anyone who does deep research, creates content, or manages complex online tasks, Comet can be a real tool.

Also, it cannot fully replace Google Chrome for everyone just yet. It does not have a mobile app or cross-device sync. So users will find it hard to work across multiple devices. Besides, since agentic AI is still new, people will still think about privacy and security.

For now, it's best to see Perplexity Comet as an essential extra tool in your digital setup. It is not a full replacement for Chrome, but a smart secondary browser for focused work, automation, and research.

Comet shows where the future of the web is moving. Now browsers don't just display information, but do tasks based on the input information.
