Perplexity Comet Review: The AI Browser That Just Went Free

Perplexity just made a move that shook up the AI browser space. Their Comet browser, which cost $200 per month when it launched in July 2025, is now completely free.

That's not a typo. A tool that was premium-only three months ago is now available to everyone. Here's what you need to know about whether it's worth the switch from Chrome or Safari.

What Perplexity Comet Actually Does

Perplexity Comet is an AI browser with a built-in assistant that lives in a sidebar while you browse. It's not just a chatbot slapped onto the side of Chrome. It can actually interact with the web pages you have open, understand what you're trying to do, and help you complete multi-step tasks without switching between a dozen tabs.

Ask it to research a topic across multiple websites, pull out the key findings, and draft an email summary. Or tell it to compare prices across five different stores and add the cheapest option to your cart. It handles the clicking, scrolling, and data gathering while you focus on making decisions.

Who This Is For (Work Pillar Alignment)

This tool is built for people who spend their days drowning in browser tabs. Researchers, writers, marketers, analysts, project managers, or anyone who does serious online work will find immediate value here.

If your job involves comparing information across multiple sources, managing email, shopping for deals, or planning travel, Comet can save you hours every week. It's especially powerful for people who do a lot of research but hate the manual labor of copy-pasting between tools.

Not great for: Teams looking for collaborative tools. Comet is a personal assistant, not a business solution. If you need something that integrates with your help desk or CRM, this isn't it.

Getting Started with Perplexity Comet

Step 1: Go to perplexity.ai/comet and download the browser for your platform (Mac, Windows, iOS, Android).

Step 2: Install and open Comet. You'll see a familiar browser interface with a sidebar on the right.

Step 3: Start browsing normally. When you need help, click the sidebar or press the keyboard shortcut to activate the AI assistant.

Step 4: Ask it to do something specific. "Summarize this article in 3 bullet points" or "Find me the cheapest flight to Denver on May 15th with no more than one stop."

Step 5: Watch it work. The assistant will interact with the page, open new tabs if needed, and report back with what it found.

You don't need special prompts or training. Just talk to it like you would a human assistant.

Key Features with Real Examples

Research Automation

Open an article in one tab and a spreadsheet in another. Tell Comet to "pull all the product names and prices from this article and add them to the spreadsheet." It does the tedious data entry for you.

Real use case: A marketer comparing competitor pricing across 10 websites finished the task in 5 minutes instead of an hour.

Email Management

Have Gmail open? Ask Comet to "summarize this 47-email thread" or "find all the messages I haven't replied to from the last week." It reads and processes your inbox without needing a plugin.

Real use case: An entrepreneur used it to draft 15 personalized follow-up emails in one sitting, all matching his writing style.

Intelligent Shopping

Tell it "Find me running shoes under $100 with at least 4.5-star reviews." Comet will open tabs on different retailer sites, compare live prices, and show you the best options side by side.

Real use case: A parent planning a birthday party saved $80 by having Comet compare decorations and supplies across six stores.

Travel Planning

Need flights with very specific criteria? "Direct flights only, Alaska Airlines preferred, leaving Friday after 2pm, under $400." Comet searches multiple airline sites simultaneously and presents the options.

Real use case: A consultant booked a complex multi-city trip in 10 minutes by having Comet handle all the comparison work.

Built-in Tools

Comet includes dedicated modules for Discover (personalized news), Spaces (project organization), Shopping, Travel, Finance (budgeting and expense tracking), and Sports updates. These aren't separate apps. They're baked into the browser and work together with the AI assistant.

Pricing Breakdown

Here's where it gets interesting. The browser is free, but the real power comes from Perplexity's subscription tiers.

Free (Standard):

• Full Comet browser access
• 5 "Pro Searches" per day (deep research queries)
• Basic AI models
• Limited file uploads
• Access to Shopping, Travel, Finance, Sports tools
• Cost: $0

Pro ($20/month):

• 300+ Pro Searches per day
• Advanced AI models (GPT-5 Thinking, Claude Opus 4.1, Gemini)
• Unlimited file uploads and analysis
• Image and video generation
• Cost: $20/month

Max ($200/month):

• Unlimited Pro Searches
• Fastest access to newest AI models
• Early access to all new features
• Email assistant (drafts replies, organizes inbox, schedules meetings)
• Background assistant (runs multiple tasks while you work)
• Everything from Pro tier
• Cost: $200/month

Comet Plus ($5/month add-on):

• Premium publisher content (like Apple News)
• Available as standalone or included with Pro/Max
• Cost: $5/month (free with Pro/Max)

Most people will be fine on the free tier. If you do serious research daily, Pro makes sense. Max is for professionals who live in their browser and need unlimited capability.

What Perplexity Comet Is Bad At

No team collaboration. This is a solo tool. You can't share workspaces, assign tasks to team members, or integrate with business systems like Zendesk or Slack. If you need team features, look elsewhere.

Limited control in business contexts. You can't set custom rules for how the AI behaves, define specific workflows, or control exactly which knowledge sources it uses. It's built for general web tasks, not specialized business processes.

Browser-only actions. Comet can only do what you could do manually in a browser. It can't make API calls, update databases, or perform true back-end operations. It's clicking and typing on web pages, not integrating with software.

Learning curve for complex tasks. While basic commands are intuitive, getting the most out of multi-step automation takes practice. You'll spend your first few days figuring out how to phrase requests effectively.

Pro Search limits on free tier. Five deep research queries per day sounds like a lot until you're three hours into a project and hit the wall. Heavy users will need to upgrade.

Comparison to Alternatives

vs. Google Chrome: Chrome is just a browser. Comet is a browser with a built-in research assistant. If you're happy manually juggling tabs, Chrome is fine. If you want help, Comet is the clear winner.

vs. The Browser Company's Dia: Dia (in beta) focuses more on visual organization and workspace management. Comet focuses on task automation and research. Dia is better for creative workflows. Comet is better for information-heavy work.

vs. Arc Browser: Arc has innovative tab management and a cleaner interface. But it doesn't have agentic AI. You still do all the work manually. Comet automates the tedious parts.

vs. ChatGPT in a separate tab: This is what most people do now. Open ChatGPT, copy-paste from websites, ask questions, repeat. Comet eliminates the copy-pasting and lets the AI interact directly with web pages. It's significantly faster.

vs. Microsoft Copilot: Copilot lives inside Microsoft apps and helps with Office tasks. Comet lives in your browser and helps with web-based work. They complement each other rather than compete.

Verdict: Who Should Use Perplexity Comet

Use Comet if:

• You spend 3+ hours per day researching online
• You're constantly comparing information across multiple websites
• You manage a busy inbox and hate drafting replies
• You shop around for deals and want automatic price comparison
• You're a solo worker who doesn't need team collaboration
• You're curious about AI browsers and want to try one risk-free

Skip Comet if:

• You're happy with your current browser and don't feel slowed down
• You need team features or business system integrations
• You only browse casually (email, news, social media)
• You prefer doing everything manually and don't trust AI assistants
• You work in a locked-down corporate environment that won't allow new browsers

Work Pillar Notes

This tool hits the Work pillar sweet spot. It directly addresses the biggest productivity drain knowledge workers face - too much time gathering information, not enough time using it.

The free tier is genuinely useful (not a teaser), which means you can test it on real work without commitment. And because it's browser-based, it works with all your existing web tools. No integrations needed.

The automation capabilities are practical, not science fiction. You won't replace your job with Comet, but you will finish your tasks faster and with less frustration.

If you're skeptical about AI tools because they promise too much and deliver too little, Comet is worth 30 minutes of your time. Download it, try three real tasks from your actual workday, and see if it saves you time.

That's the test. If it doesn't make your work life easier in the first week, uninstall it and move on. But if you're spending hours every week doing mindless browser tasks, there's a good chance Comet will become your new default browser.

Bottom line: A $200/month tool that went free is worth trying. Worst case, you delete it. Best case, you get hours back every week.
