What is Comet, Perplexity’s browser

Perplexity became known for turning internet search into something more like a conversation. Instead of a list of links, you get a direct answer, with sources cited. Comet is the next step in that vision: a complete browser, developed by Perplexity itself, that integrates artificial intelligence natively in every tab, every search, and every interaction with web pages. It’s not a Chrome extension or a plugin. It’s a proprietary product, built from scratch so that AI is the center, not an accessory.

The proposal is ambitious. While Google and Microsoft are still trying to fit AI into their existing browsers, Comet starts from a different philosophy: the browser should understand the context of what you’re doing, suggest actions, summarize pages, compare products, and answer questions without you needing to open a new tab or type in a separate search field. It’s like having an assistant reading along with you.

The short answer to “is it worth it?” depends on who you are. If you already use Perplexity regularly and want AI to be present in everything you do on the browser, Comet has serious arguments. If you rely on an established ecosystem of extensions, synchronization with other devices, or are satisfied with Chrome or Edge, the numbers may not add up. Keep reading to understand why.

How AI works inside the browser

Comet’s differentiator isn’t in loading pages faster. The advantage is what happens after the page opens. The browser monitors the content of the active tab and provides a side panel where you can ask questions about that specific content. Reading a technical article in English? You ask for a summary in Portuguese. On a product page in an American store? You ask if the price is good compared to other options you’ve seen before.

This feature is informally called context-aware browsing. The AI doesn’t just respond with knowledge it was trained on up to a cutoff date—it reads what’s on the screen with you, in real time. The difference from manually copying and pasting text into ChatGPT is huge in terms of practicality. You don’t interrupt your reading flow to open another app.

Comet also offers what Perplexity calls agentic browsing, or agent-based browsing. In this mode, you give a broader instruction, like “research the three best cell phone plans available in Brazil for heavy data use and show me a comparison,” and the browser opens tabs, reads pages, compares information, and delivers you a summary. It’s different from a simple search shortcut; the browser acts on its own to complete the task.

Performance and resource consumption

Because it’s based on Chromium (the same open source base that powers Google Chrome and Microsoft Edge), Comet inherits both the strengths and known weaknesses of this engine. Website compatibility is virtually universal. Chrome Web Store extensions work normally, which reduces the switching cost for those who already have an established workflow.

The point of caution is RAM memory consumption. Chromium-based browsers are not lightweight by nature, and the AI layer added by Comet increases this consumption. According to public information from Perplexity, part of the AI processing is done in the cloud, which reduces local hardware demands, but it depends on a stable internet connection. On unstable or slow connections, intelligent functions are compromised.

For everyday use on a machine with 16 GB of RAM or more, performance tends to be satisfactory. On more modest computers with 8 GB, it’s worth monitoring whether the browser starts competing with other open programs. Perplexity hasn’t officially published detailed minimum requirements so far, so check the latest documentation on their website before installing.

Interface, privacy, and the practical side of everyday use

Comet’s interface is clean, inspired by minimalist browsers like Arc. The address bar also functions as an intelligent search field: you can type a normal URL or a question, and the browser decides whether to open a page or activate the AI. This decision is made automatically and, in practice, works well in most situations.

The privacy question is where the debate gets heated. For AI to understand the context of what you’re reading, it needs to process the content of the pages you visit. Perplexity claims that data is used to generate responses and not to train models without user consent, but the complete privacy policy deserves a read before you use the browser to access sensitive information, such as bank documents or contracts. This advice applies to any product that processes page content in real time.

Another practical point: the search history is tied to your Perplexity account. This means that if you switch computers and log in, your usage context follows you. For those using more than one device, it’s a real convenience. But it also means your browsing data lives on company servers.

Comet in Brazil: import, support, and actual costs

Comet is software, not hardware, so it doesn’t go through Anatel approval. You download it directly from Perplexity’s website, with no import bureaucracy. But a few points deserve attention before adopting it as your main browser.

The free plan has a daily limit on advanced queries. For intensive use, the Pro plan is necessary, and the dollar amount (around US$ 20 monthly) fluctuates with the exchange rate. In 2026, depending on the dollar, this represents between R$ 110 and R$ 130 per month—an amount that needs to make sense in your budget. If you already pay for Perplexity Pro to use in the app or on the website, verify whether Comet access is included in the same plan before paying separately.

Portuguese language support is still partial. The AI understands and responds in Portuguese with good quality, but the browser interface itself is in English. For most tech users who follow American launches, this isn’t a serious obstacle. But it’s a real fact that influences the experience.

Pros and cons

Pros:

• AI integrated natively, without needing extensions or extra tabs
• Compatible with Chrome Web Store extensions, easing migration
• Agentic browsing for complex research tasks
• Real-time page summarization, with Portuguese response support
• History synchronized across devices via Perplexity account
• Free access with basic features available

Cons:

• Main interface in English, without complete localization for Brazil
• Pro plan necessary for intensive use, with costs in dollars subject to exchange rates
• High RAM consumption, especially on more modest computers
• Privacy dependent on Perplexity’s content processing policy
• Mobile version still in development, without parity with desktop
• Less mature ecosystem than Chrome or Edge in terms of technical support

Competitors and alternatives in Brazil

Microsoft Edge with Copilot is the most accessible alternative for those who want AI in the browser at no additional cost and with a Portuguese interface. Arc appeals to those who prioritize design and tab organization, but the AI is still less powerful. Opera One brings free integrated AI and has a strong presence in Brazil, making it a legitimate option for those who don’t want to spend on a Pro plan.

If you want to understand how to browse more efficiently day to day, including more demanding searches that can complement using a high-performance notebook, it’s also worth checking our guide on gaming notebooks up to R$ 6000, where we discuss configurations that support this kind of intensive use well.

Frequently asked questions about Comet

Does Comet work on Windows or only Mac?

According to public information from Perplexity, the browser was launched for macOS and Windows. The version for iOS and Android was in development at the time of publication of this article, but you should check the official website to confirm the current status of each platform.

Do I need to pay to use Comet?

There is a free plan, but it has limits on the number of advanced queries per day. For intensive AI use, the Pro plan is necessary. The announced value in the US hovers around US$ 20 monthly, and if you already subscribe to Perplexity Pro for other platforms, confirm whether Comet is included before paying separately.

Does Comet collect data from the pages I visit?

For the AI to understand the context of what you’re reading, it processes the content of active pages. Perplexity claims not to use this data to train models without consent, but reading the complete privacy policy is recommended, especially before using the browser to access sensitive documents.

Do my Chrome extensions work on Comet?

Yes. Because it’s based on Chromium, Comet is compatible with Chrome Web Store extensions. This makes migration simpler for those who already rely on tools like password managers, ad blockers, or productivity extensions.

Is Comet worth it in 2026?

Comet represents a genuine bet on how the browser can evolve. It’s not a cosmetic AI addition; it’s a paradigm shift in how you interact with the web. Agentic browsing, contextual summarization, and integration with the Perplexity ecosystem form a coherent and useful set for those who have already adopted AI as part of their workflow.

That said, the product still has rough edges. The English interface, the cost of the Pro plan in dollars, and the absence of a mature mobile version limit its appeal to part of the Brazilian audience. It’s not a product for everyone yet.

Recommended for: professionals and students who already use Perplexity frequently, do lots of research during the day, and want AI integrated without having to switch between apps. It also works well for those working with English content who want automatic summaries in Portuguese.

Those who depend on Android synchronization, prefer a Portuguese interface, or have no interest in paying a monthly dollar-denominated subscription will find more practical alternatives in Edge with Copilot or Opera One, both available for free and with strong presence in Brazil.

Price range: free with limitations; Pro plan around US$ 20 per month (approximately R$ 110 to R$ 130 depending on exchange rates, subject to variation).
