Perplexity Comet 2025: When Your Browser Becomes Your Intelligent Assistant

Imagine for a moment that your web browser truly understands what you’re looking for. No more juggling fifteen open tabs to compare prices, manually copying information from one site to another, or wasting twenty minutes planning a simple trip. This is exactly what Perplexity Comet offers, a browser that doesn’t just display web pages, but thinks and acts with you.

In October 2025, Perplexity made a bold choice: making Comet completely free for all users worldwide. What was previously reserved for premium subscribers at $200/month is now accessible to everyone. A decision that could well change how we use the internet daily.

Introduction

In my web development practice for over 15 years, I’ve seen many innovations come and go. But Comet represents something different. It’s not simply a new browser with additional features - it’s a new way of thinking about our relationship with the internet. Instead of searching for information, you converse with your browser to obtain it. Instead of repeating the same tasks every day, you delegate them to an artificial intelligence that learns your habits.

Let’s explore together how Comet concretely transforms our digital daily life, whether you’re a simple user, a busy professional, or a student seeking better learning tools.

What Is Perplexity’s Comet?

A Browser That Understands Your Intentions

Let’s take a concrete example to understand the fundamental difference. You’re looking for a new mobile phone. With a classic browser like Chrome, you open Google, type “best smartphone 2025,” browse ten comparison sites, open fifteen tabs, note prices in a document, then try to remember which site you saw that interesting feature on.

With Comet, you simply ask: “I’m looking for a smartphone with good battery life and a powerful camera, maximum €600 budget, what are the best options currently in France?” The browser responds with a clear summary, compares relevant models, indicates current prices at different vendors, and cites all its sources so you can verify.

This ability to understand your intentions rather than simply displaying search results radically changes the experience. You shift from “information seeker” to “conversing with the internet.”

Technical DNA: Chromium Powered by AI

Technically, Comet relies on Chromium, the same base as Google Chrome. This means excellent news: all your favorite Chrome extensions work perfectly. You lose nothing by switching to Comet, you gain an additional layer of artificial intelligence.

This AI isn’t just a simple integrated chatbot. It’s what’s called an “agentic AI” - it doesn’t just answer your questions, it acts concretely for you. It can navigate websites, fill out forms, compare information across multiple pages simultaneously, and even execute complex action sequences you’ve taught it.

The Comet assistant appears in each new tab, discreet but always ready to help. It maintains the context of your previous conversations, meaning you can deepen a subject without having to repeat basic information each time.

Personal Use: Transform Your Digital Daily Life

Talk to Your Browser Like a Friend

The first thing that surprises with Comet is its ability to maintain a natural conversation. You no longer search with keywords, you discuss.

Imagine preparing a trip to Tokyo. Instead of multiplying separate searches, you can have a progressive conversation:

You: “I want to go to Tokyo in February, is it a good time?”

Comet: explains the weather, cultural events, busy periods

You: “Find me direct flights from Paris, with return a week later”

Comet: compares airlines, schedules, and prices

You: “And for accommodation, I prefer a lively but not too touristy neighborhood”

Comet: suggests suitable neighborhoods with hotel options

All this happens in one fluid conversation. The assistant remembers you talked about Tokyo, February, a week’s stay. You don’t have to repeat everything.

Personalized Shortcuts: Your Magic Wand

One of Comet’s most powerful features is personalized shortcuts activated by the “/” command. Imagine them as spells you create once and can instantly cast afterward.

Some practical examples:

“/groceries”: opens your usual grocery sites (Carrefour, Leclerc, etc.) and automatically checks weekly promotions on your favorite products

“/weather-week”: displays the next 7 days’ weather with adapted clothing recommendations

“/news-tech”: summarizes important French tech news of the day in 3 minutes of reading

“/bills”: connects to your main accounts (electricity, internet, mobile) and checks if bills need paying

These shortcuts can save you 15 to 20 minutes per day. That’s the equivalent of over 90 hours per year recovered from repetitive tasks!

Automating Daily Tasks

Comet particularly excels at automating those small tasks that take our time without us realizing it.

Travel planning: “Find me a Paris-Tokyo flight for February, compare prices and schedules, then book the cheapest option with acceptable layover” - Comet will navigate multiple sites, compare, and even make the reservation for you if you authorize it.

Optimized online shopping: “I want to buy this Nespresso coffee machine, find me the best price in France with free delivery” - The assistant automatically compares Amazon, Fnac, Darty, Boulanger, and presents the best deal.

Managing administrative appointments: “Book me a general practitioner appointment next week, preferably late afternoon” - Comet can navigate Doctolib, check availability, and book.

Professional Use: Productivity at Another Level

Enterprise Security: Working Serenely

I know what you’re thinking: “This is all well and good, but can I really use this with my company’s data?”

Perplexity thought about professionals from the start. Comet benefits from serious security certifications: SOC 2 Type II for organizational processes, GDPR compliance for Europe, and even HIPAA for health data.

By default, your data is stored locally on your machine with end-to-end encryption. Only explicit requests you make to the assistant require minimal access to concerned data. And you can activate a reinforced incognito mode where absolutely nothing is collected or stored.

For companies wanting to go further, Comet Enterprise Pro offers administrator controls allowing fine management of permissions, downloads, and access.

Integration with Your Daily Tools

One of Comet’s strengths in professional environments is its native integration with Gmail and Google Calendar.

Intelligent email management: “Summarize my unread emails this morning and draft responses for the three most urgent” - Comet analyzes your messages, understands context, and proposes responses adapted to your usual tone.

Automatic planning: “Schedule a meeting with Jean and Marie next week, one hour is enough, and create the Zoom link” - The assistant analyzes calendar availability, finds a common slot, sends invitations, and generates the video conference link.

Meeting preparation: Before an important client meeting, ask: “Research recent information on XYZ company and prepare me a 5-minute brief” - Comet will search for news, latest press releases, changes in management team, and synthesizes everything for you.

Automated Complex Workflows

This is where Comet truly shows its power. Imagine being able to describe a complex process in natural language, and the browser executes it for you.

Automated competitive intelligence: “Analyze the last five days’ news from our three main competitors (Company A, B, and C), identify strategic trends, and prepare me a summary report with attention points” - Comet will navigate these companies’ sites, their press releases, press articles mentioning them, then compile everything into a structured document.

Express market research: “Study the French electric bike market: market size, annual growth, main players, and recent innovations” - In a few minutes, you have a complete overview with cited sources.

Multi-tool project tracking: “Check the progress of our three ongoing projects on Notion, identify overdue tasks, and send a reminder to concerned people” - Comet navigates your Notion, analyzes project status, and can even draft and send follow-up messages.

Enterprise Vigilance Zones

Despite all its certifications, Comet introduces new security challenges you need to know about. Researchers have identified a vulnerability called “CometJacking” that allows malicious URLs to manipulate the assistant.

For secure professional use, here are my recommendations after testing Comet for several months:

Never enter ultra-sensitive information directly in prompts: passwords, credit card numbers, strategic trade secrets. Even if it’s tempting to ask “connect to my bank account with password XYZ,” resist.

Regularly check permissions granted to Comet on your Gmail, Calendar, and other service accounts. Enable two-factor authentication everywhere.

Use separate profiles: create a Comet profile for work and another for personal use. This compartmentalizes data and reduces risks.

Train your teams: humans remain the weak link. Explain to your collaborators how to use Comet securely.

Educational Use: Learning Differently

Free For All Students Worldwide

Since September 2025, Perplexity offers completely free access to Comet for all students worldwide. An initiative that democratizes access to AI learning tools that were previously unaffordable for most.

To benefit, simply verify your student status via a university email address or school certificate. In a few minutes, you access all premium features.

Study Mode: Really Learning, Not Cheating

Comet’s Study Mode represents a revolutionary approach to learning. Unlike ChatGPT which directly gives you the answer, Study Mode guides you to find the solution yourself.

Let’s take a concrete example. You’re a math student stuck on a probability problem:

You: “I don’t understand how to calculate the probability of getting exactly 3 heads in 8 coin tosses”

Study Mode: “Before solving this problem, tell me: do you know the binomial law? If yes, can you remind me of its formula?”

You: “Yes, it’s P(X=k) = C(n,k) × p^k × (1-p)^(n-k)”

Study Mode: “Perfect! Now, in your problem, can you identify what n, k, and p represent?”

This Socratic approach forces you to think, activate your knowledge, and build your reasoning. You don’t just get an answer to copy - you truly learn.

Automatic and Intelligent Review Cards

A particularly appreciated feature by students: automatic generation of interactive review cards.

You upload your 50-page course on the French Revolution (PDF, Word format, or even photos of your handwritten notes). Comet analyzes the document and automatically generates:

Thematic review cards: key dates, important figures, major events, concepts to remember

Adaptive quizzes: the AI generates questions and adapts difficulty according to your answers. If you master chronology well but less the economic aspects, it insists on the latter.

Visual mind maps: connections between concepts, causes and consequences, logical links

Progress tracking: you visualize what you master well and what still needs work

Academic Research with Verifiable Sources

For master’s or doctoral students, Comet’s ability to provide cited and verifiable sources changes everything. Each piece of information is accompanied by links to original sources, greatly facilitating thesis and dissertation writing.

You can ask: “Find me the main studies on climate change impact on Mediterranean biodiversity published after 2020” - Comet will search academic databases, present the most cited studies, and format citations according to the standard you use (APA, MLA, Chicago, etc.).

Ethical Use: A Shared Responsibility

Be careful, Comet isn’t a tool for cheating. A viral incident in September 2025 showed a student using Comet to automatically complete a Coursera assignment in seconds. Perplexity CEO Aravind Srinivas publicly condemned this practice: “Absolutely don’t use Comet this way.”

Golden rules for ethical use:

Use Comet as a learning assistant, not as a substitute for your personal reflection

Be transparent: if you use AI for your work, mention it in your methodology

Develop your critical thinking: don’t take Comet’s answers at face value, verify, question, deepen

Respect your institution’s rules: some universities prohibit AI use for certain work, inform yourself

Advanced Features and 2025 Innovations

Voice Commands: Navigate Hands-Free

Comet integrates a particularly impressive voice interface. Activated by the Shift + Alt + V shortcut, it allows complete voice control of the browser.

This is particularly useful when cooking with a recipe open in a tab: “Comet, go to the next step,” “Comet, set a 15-minute timer,” “Comet, convert 8 ounces to grams.”

Or when working with busy hands: “Close all tabs except this one,” “Open my Spotify playlist,” “Send a message to Marie saying I’ll be 10 minutes late.”

Voice recognition uses OpenAI’s GPT-realtime model, giving remarkable precision even with regional accents or familiar expressions.

Background Assistant: Intelligent Multitasking

For Max users (paid version), Background Assistant represents evolution toward true intelligent multitasking.

Imagine you’re working on an important presentation. Meanwhile, Background Assistant can:

Perform continuous competitive intelligence: monitor your competitors’ news and alert you in case of important announcement

Manage multiple projects in parallel: check progress on different tools (Notion, Trello, Asana) and give you regular updates

Prepare your next tasks: while you finish your presentation, the assistant can already research information for your next project

It’s like having a digital personal assistant working in the background while you focus on the essential.

Multimedia Content Generation

With Veo 3 integration (Google’s video generation model), Comet now allows creating multimedia content directly in the browser.

Create an advertising video: “Generate a 30-second video presenting our new product, dynamic and modern style, with energetic music” - Comet creates the video, you can adjust it, then publish directly to your social networks.

Generate visuals for your presentations: “Create a modern infographic on the evolution of the electric vehicle market in France from 2020 to 2025”

Produce social media content: “Transform this blog article into 5 LinkedIn posts with adapted visuals”

Future Perspectives: Where Is Comet Going?

Mobile Version: Soon in Your Pocket

Perplexity is actively working on Comet Mobile, an adaptation designed for smartphones and tablets. This version promises:

Optimized touch interface with preserved AI capabilities - not a simple lightweight version, but a true mobile experience designed for AI

Cross-platform synchronization: start a search on your computer in the morning, continue on your phone during commute, finish on your tablet in the evening

Enhanced voice commands: on mobile, voice becomes even more natural than keyboard

Release is planned for early 2026, first on iOS then Android.

Evolving Artificial Intelligence

Comet’s architecture is designed to integrate new AI models as they’re released. GPT-5, Claude 4, Gemini 2.0 - all will be progressively integrated to constantly improve the browser’s capabilities.

Perplexity is also working on even more advanced automation capabilities, with workflows that can dynamically adapt to unexpected situations, learn from your corrections, and become increasingly personalized over time.

Extended Enterprise Ecosystem

For large organizations, Perplexity is developing Comet Enterprise Max with:

Native integrations with Microsoft 365, Google Workspace, Salesforce, and other major professional suites

Advanced governance tools to finely manage who has access to what, trace actions, and guarantee regulatory compliance
