Comet arrived to change how you use the internet
Comet is the web browser developed by Perplexity AI, the American company known for its AI-powered search engine that answers questions in natural language instead of just listing links. Launched in 2025 and established by 2026, Comet is not just another Chromium-based browser with a chatbot stuck in the sidebar. The proposal is more ambitious: integrate AI directly into the browsing flow, so you consult, search, and execute tasks without leaving the page you’re visiting. For those already using Perplexity as a daily Google substitute, Comet makes immediate sense. For those who’ve never experienced AI-powered search, it may be the most practical entry point.
The short answer to “is it worth it”? It depends on your profile, but yes, the proposal works. Perplexity’s AI inside the browser delivers what it promises: contextual answers, page summaries, integrated search, and light task automation. What you need to evaluate is whether you’re willing to switch ecosystems and if the subscription model fits your budget.

How AI Works in Practice Inside the Browser
The key insight of Comet is not having an “ask AI” button in the corner of the screen. It’s how the AI understands the context of the page you’re reading. When you open a long article, a product page, or a PDF report, Comet can summarize the content, answer specific questions about that text, and even compare it with information from other sources, all without opening a new tab.
This works because the browser injects the current page’s content as context for Perplexity’s AI model. It’s like handing a document to an assistant and asking “explain this to me”. The difference compared to copying and pasting text into a chatbot is fluidity: there’s no window switching, no broken formatting, no manual paste limits.
According to Perplexity, the browser also supports light task automation, called “agentic browsing”. In practice, this means you can ask Comet to fill out simple forms, navigate between pages to gather information, or execute repetitive sequences. The feature still has limitations on sites with complex authentication or CAPTCHAs, which is expected for maturing technology.
Does Integrated Search Replace Google?
For many users, yes. Perplexity’s search engine answers in natural language with cited sources, which speeds up research that normally requires opening five different tabs. For simple commercial searches, like “best laptop price”, Perplexity still loses to Google in scanning Brazilian stores. But for content research, technical comparisons, and factual questions, the experience is noticeably more direct.
Performance and Resource Consumption
Being based on Chromium, the same engine that powers Google Chrome, Comet inherits both the advantages and the characteristic RAM appetite of that foundation. According to manufacturer information and public user reports, resource consumption is similar to Chrome with some active extensions, which means on machines with 8 GB of RAM or less you may feel the system heavier during long sessions with many open tabs.
The real performance gain noticeable to users is in the speed of AI responses. Since Perplexity runs on the company’s servers rather than locally on your machine, your internet connection quality matters more than your computer’s specs. On connections above 50 Mbps, responses arrive in seconds. On unstable connections, the assistant may freeze mid-response, which is frustrating.
Privacy: What You Need to Know
Using a browser with integrated AI raises legitimate privacy questions. Perplexity collects usage data to improve models, which is described in the company’s privacy policy. This means the content of pages you analyze with AI may be processed on Perplexity’s servers. For corporate use with sensitive data, read the full policy before adopting Comet as a work tool. For personal daily use, the data collection level is comparable to other browsers with cloud-based features.
Interface and Learning Curve
Comet’s interface will appeal to Chrome and Edge users. The tab layout, address bar, and keyboard shortcuts are familiar. The visual difference comes from Perplexity’s side panel, which appears on demand and doesn’t take up space when you don’t need it.
The learning curve to fully leverage the browser’s potential is low for those already using Perplexity on the web. For new users, the recommendation is to start with integrated search, use it for a few days, then explore page summarization. Task automation features are the next step and require more experimentation to understand what works and what still has limitations.
One point worth noting: Chrome extensions are compatible, which removes a common obstacle in browser migration. Password managers, ad blockers, and productivity tools you already use continue working.
Comet in Brazil: Import, Cost, and Support
Comet is software, so there’s no hardware import involved. Download is free directly from Perplexity’s website. The free plan allows basic AI use with a daily query limit. The Perplexity Pro plan, needed to fully leverage the browser’s potential, costs around US$20 per month in the United States. In local currency, the value varies with exchange rates and payment method, so check the current price directly on the platform before subscribing.
There is no local Portuguese language support for the product. Support is provided in English via Perplexity’s online channels. The browser interface has partial localization; some sections already appear in Portuguese, others are still in English, which is common for American products gradually expanding language support.
Being software without Anatel homologation (which applies to communication devices, not apps), there is no legal impediment to use in Brazil. Warranty follows Perplexity’s terms of service, without application of Brazilian Consumer Protection Code to the product itself, which is standard for foreign software services.

Frequently Asked Questions About Comet
Does Comet work in Portuguese?
Partially. The interface is undergoing localization, with some sections already in Portuguese and others still in English. AI responses to Portuguese-speaking users work well; Perplexity’s model understands and responds in Portuguese without additional configuration.
Do I Need to Pay to Use Comet?
Not for the basics. Download and the free plan allow browser use and a limited number of daily queries. For intensive use with access to advanced models and unlimited queries, the Pro plan is necessary. Check the current price in your local currency on Perplexity’s website.
Does Comet Completely Replace Chrome?
For most personal and productivity uses, yes. Chrome extension compatibility eliminates the main migration barrier. The exception is very specific integrations with Google services, which may perform better in native Chrome.
Are My Data Safe in Comet?
Perplexity processes the content of pages you analyze with AI on their servers. For daily personal use, the risk is comparable to other cloud services. For confidential corporate data, read Perplexity’s complete privacy policy before adopting the tool.
Is It Worth It?

Comet is one of the most honest products in the “browser with AI” category released in recent years. It doesn’t just glue a chatbot to the sidebar; it builds the browsing experience around AI, and that makes a real difference in the daily life of those who research, read, and produce content on the web.
If you already use Perplexity as your primary search tool, installing Comet is a natural evolution. If you haven’t experienced AI-powered search yet, Comet’s free plan is one of the best ways to understand what this technology delivers concretely, without immediate financial risk.
