Comet has arrived, and Perplexity wants to change how you browse

Perplexity became known for its artificial intelligence search engine, the one that answers your questions directly instead of throwing a list of links on your screen. Now the company went further and launched Comet, a complete browser built with AI at its core, not as an optional feature you activate through a hidden button, but as an essential part of the experience. The idea is that the browser understands what you’re doing and actively helps, without you needing to switch tabs or open a separate chat window.

The short answer for those with their finger on the trigger: Comet is interesting and shows a different path for what a browser can be, but still carries important limitations for the Brazilian user. Official availability in Brazil is uncertain at the time of publication, and the extension ecosystem still doesn’t come close to what Chrome or Firefox offer. If you’re a tech enthusiast and want to be on the cutting edge, it’s worth following closely. If you need a stable browser for work today, the scenario still calls for caution.

What Sets Comet Apart from Any Other Browser

Most modern browsers added AI as an extra layer: you click a button, open a side panel, type a question and read the answer. Comet inverts that logic. According to Perplexity, AI is the engine underneath everything, capable of observing the context of the page you’re visiting and acting proactively, whether summarizing a long article, comparing prices as you shop at a store, or filling out forms based on your preference history.

The concept that the company calls agentic browsing is the central point here. Think of it this way: instead of you telling AI to do a task, it observes what you’re trying to do and offers help before you even ask. It’s like having an assistant watching your screen and intervening when they notice you’re wasting time. In practice, this means the browser can, for example, fill in checkout fields, organize tabs by theme, or search for complementary information about what you’re reading, all integrated seamlessly.

Another differentiator is that Comet uses Perplexity’s own search index, which has already stood out for providing answers with source citations instead of just links. This means that when you search within the browser, you receive a structured answer with references, not a list of ten results you need to open one by one to figure out which one works.

Performance and Usability in Daily Use

Being based on Chromium (the same open-source project that powers Chrome, Edge, and Brave), Comet inherits a solid, proven foundation. Chrome extensions work in Comet, which resolves much of the compatibility concern for anyone who already has a set of tools installed in their current browser.

The point of attention is resource consumption. Browsers with integrated AI tend to be heavier on RAM than their counterparts without these active features. Perplexity hasn’t released official memory consumption or performance benchmarks at the time of publication, so the best thing to do is check community reports on specialized forums like Reddit (r/perplexity_ai) and verify that your machine has at least 8 GB of RAM for a smooth experience. Older machines or those with modest specs might feel the difference.

Privacy is another item you need to evaluate carefully. A browser that observes the context of the pages you visit to offer proactive suggestions necessarily processes a significant amount of data about your browsing. Perplexity makes its privacy policy available on its official website, and reading it is recommended before switching your primary browser, especially if you deal with sensitive data at work.

Integration with the Perplexity Ecosystem

Those who already use Perplexity Pro will find Comet as a natural extension of that ecosystem. Searches made in the browser feed into the same history and preferences on your account, and the assistant has access to the context of previous conversations to provide more relevant answers over time. It’s a model similar to what Apple does with Safari and iCloud, or Google with Chrome and Google account, but centered on generative AI (language models that generate text and reason about information) rather than syncing bookmarks and passwords.

For those who don’t subscribe to the Pro plan, Comet works with limited assistant features, using Perplexity’s free plan. Basic search with natural language answers remains available, but features like full agentic browsing, deeper searches, and a higher volume of queries per day are restricted to subscribers. Pro pricing in the USA hovers around US$ 20 per month, but the Brazilian real equivalent can vary depending on exchange rates and taxation, something worth checking directly on the platform.

Comet in Brazil: What You Need to Know Before Installing

Comet has no official distribution in Brazil at the time of publication. This means there’s no Portuguese support, localized customer service, or guarantee of compliance with Brazilian legislation like the LGPD (General Data Protection Law). Downloads are done directly from Perplexity’s website, with no national intermediary.

For browser software, there’s no Anatel approval requirement like there is for physical devices, so that’s not a technical obstacle. The real problem is support: if something goes wrong, you’ll depend on English documentation and community forums. The Comet interface at launch was in English, with no confirmed timeline for full Brazilian Portuguese localization.

An important practical aspect: Brazilian users who use services like electronic invoicing (Nota Fiscal eletrônica), banking systems with specific authentication, or government platforms should test compatibility before migrating your primary browser. The Chromium base helps with overall compatibility, but specific features may behave differently. For comparisons of other products going through this same evaluation process for the Brazilian market, such as the Apple Watch SE 2 still worth buying in 2026?, the point of local availability and support is always a deciding factor.

Pros and Cons

Pros:

• AI natively integrated, not just as an extension or side panel
• Agentic browsing concept that can reduce repetitive navigation tasks
• Chromium base ensures compatibility with Chrome extensions
• Search with structured answers and source citations, different from traditional search
• Seamless integration for those already subscribing to Perplexity Pro

Cons:

• No official distribution in Brazil and no Portuguese support
• Pro plan price in reals subject to exchange rate variation and potentially expensive
• Resource consumption not officially detailed, potentially heavy on modest machines
• Extension ecosystem and customization options still smaller than established Chrome
• Privacy concerns relevant for those using the browser in sensitive contexts
• No clear timeline for Brazilian Portuguese localization

Competitors and Alternatives in Brazil

Microsoft Edge is the most direct alternative for those who want integrated AI with official support in Brazil, Portuguese interface, and no additional cost. Brave caters to those who prioritize privacy and already have a built-in AI called Leo. Opera One has a similar proposal to Comet in terms of AI at the center of the experience, but with better localization and more consolidated presence.

Frequently Asked Questions About Comet

Does Comet work with Chrome extensions?

Yes. Because it’s based on Chromium, Comet is compatible with Chrome Web Store extensions. Installation follows the same process as any browser built on that platform, and most popular extensions should work without issues.

Do I need to pay to use Comet?

Comet has a free tier linked to Perplexity’s basic plan, which includes limited AI searches. Advanced features, like full agentic browsing and higher query volumes, require the Pro plan. The exact value in reals should be verified on the official website, as it’s subject to variation.

Is Comet safe in terms of privacy?

Perplexity publishes its privacy policy on its official website, and reading it is the first step before any decision. The contextual browsing model, where the browser observes what you’re doing to offer help, implies browsing data collection. For use with sensitive or corporate information, evaluating the data policy is essential.

When does Comet officially arrive in Brazil?

There was no confirmed launch date for Brazil at the time of publication. Download is already possible from Perplexity’s website, but without localized support or Portuguese version. Follow the company’s official channels for updates.

Is It Worth It?

Comet represents a genuine bet on a different browser model, where AI is not decoration but infrastructure. For those already living within the Perplexity ecosystem and using the service daily, it makes sense to experiment. The agentic browsing proposal, if it delivers on its promises in practice, can save real time on repetitive search and browsing tasks.

For the average Brazilian user, however, the lack of official support, the English interface, and questions about privacy and resource consumption call for patience. Alternatives like Edge with Copilot or Brave with Leo already deliver integrated AI with much less friction and Portuguese support.

Recommended for: tech enthusiasts who already subscribe to Perplexity Pro, research and content professionals who do many searches daily, and those who want to experience what might be the next step in browser evolution before it becomes mainstream.

Price range: free download with limited basic plan; Pro plan around US$ 20/month in the USA, with Brazilian real equivalent variable depending on exchange rate and taxation at the time of subscription.
