Most AI tools are great at talking—but not always at telling the truth.
They generate plausible-sounding content, not verified facts. And if you’re a marketer, that’s a problem. You need more than ideas: you need reliable insights, current data, and citations you can trust.
Perplexity’s Comet might become your new best friend.
What Is Comet, and Why Should Marketers Care?
Comet is a new AI-powered browser from Perplexity. It’s built on Chromium (like Google Chrome and Microsoft Edge), so if you are using one of these browsers, switching is quick and seamless.
If you’re used to using AI tools like ChatGPT or Claude, Comet’s interface will be familiar, but it functions differently.
Comet is a bold hybrid that combines the browsing power of Chrome with the intelligence of an AI platform—adding context, citations, and speed to your workflow.

Browser Comparison: Comet vs Chrome
If you’re using Chrome for research and ChatGPT for writing, you’re already doing better than most. But you’re still doing more manual work than you need to.
Chrome is great at opening tabs—but it doesn’t analyze or summarize anything.
Comet, on the other hand, actively reads the pages you visit, summarizes key points, and provides clickable citations for every insight.
It’s an AI that works right alongside your research—an intelligent assistant that pulls in real-time information and keeps your findings grounded in source-backed truth.
Here’s how Comet compares to Chrome on typical marketing tasks:
AI Platform Comparison: Comet vs ChatGPT
So, which AI platform is better? It depends on the task.
Because Comet is the first of its kind, it still feels like a work in progress, with some users saying that some of its features aren’t working quite as expected yet.
Here’s how Comet’s AI features compare with ChatGPT.
The good news is, you don’t have to choose between them. For most people, the smarter move is to combine both.
Use Comet for research, analysis, and validation.
Use ChatGPT for outlining, writing, and reworking your ideas.
Because you can access the ChatGPT model from within Comet, you may find that you can seamlessly use both for different tasks.
Comet Features That Solve Real Marketing Problems
Beyond browser basics, what makes Comet truly useful are the features built into its core. These aren’t just technical bells and whistles—they’re practical tools that align with the everyday tasks that marketers face, from competitor research to trend analysis.
For example, Comet offers:
Access to Multiple AI Models
Comet interface with model menu open.
Comet gives you access to the latest models of ChatGPT-5, Claude, Gemini, and more—all within a single interface. This means you can toggle between models to get different types of insights without switching platforms.
For marketers, this flexibility is powerful for:
- Comparing how different sources frame the same topic
- Testing how clearly a topic surfaces across channels
- Cross-checking summaries for consistency
- Using Perplexity for research and ChatGPT for writing—or Claude for coding tasks— all within the same interface
Context-Aware Sidebar With Inline Citations
Another key to Comet’s usefulness is its Assistant mode. Comet’s assistant lives in your browser sidebar. As you browse, it reads the content alongside you—offering instant summaries, suggested follow-ups, and clickable citations.
Comet’s assistant works alongside your conversations.
You’re never left guessing where a stat came from, or flipping between pages to verify something. It’s seamless, real-time support.
Opening and closing the assistant is as easy as clicking a single button. The two buttons to its left allow you to instantly summarize the current web page or launch voice mode.
Summarize this web page and Launch voice mode tools.
Autopilot Mode for Structured Research
In Comet, when you ask a complex question—like comparing competitors, following links, or summarizing multiple sources—Comet automatically enters autopilot mode.
Comet’s agent gets to work to complete your task for you. It can:
- Browse multiple sites
- Follow internal links
- Synthesize a structured, sourced answer
You don’t need to turn anything on. If your task is complex enough, Autopilot just kicks in to perform multi-step tasks—while you work on something else.
Integrated App Connectors
Comet includes seamless connectors for Gmail, Google Calendar, Slack, and other productivity tools—with no extensions needed. The first time you ask your assistant to do a task using an external app, it will ask you for your sign-in information.
Once you grant permission through a secure login, you won’t have to do it again. You can ask the assistant to summarize emails, schedule meetings, or create calendar events using natural language. It all happens directly in the sidebar, with no extra setup.
Cross-Tab Intelligence
Comet lets you reference content from other open tabs using the @tab command—no copying, pasting, or losing context.
If you have three competitor websites open, you can write:
“Compare the messaging in @tab1, @tab2, and @tab3. Summarize their core positioning.”
Comet will scan those tabs, analyze the content, and return a unified response. This is particularly powerful for marketers comparing tone, value props, or product positioning across multiple sources.
What Do Early Users Say About Comet?
