# What is Comet’s Browser Engine?

> Comet is a Chromium-based browser from Perplexity. Learn what that means for web compatibility, Chrome extension support, and everyday browser features.

<p><b>Comet is a Chromium-based browser</b> that combines the familiar web browsing experience you're used to with powerful AI capabilities from Perplexity.</p>

<h2 id="h_608c9d642e">What does "Chromium-based" mean?</h2>

<p>Chromium is an open-source web browser project that serves as the foundation for many popular browsers, including Google Chrome, Microsoft Edge, and Opera. When we say Comet is Chromium-based, it means:</p>

<ul>
  <li>
    <p><b>Familiar Interface</b>: Comet uses the same core browser engine and interface elements you're already familiar with from other modern browsers</p>
  </li>

  <li>
    <p><b>Web Compatibility</b>: Comet can render websites and web applications just like Chrome, ensuring excellent compatibility across the internet</p>
  </li>

  <li>
    <p><b>Extension Support</b>: You can install most Chrome extensions in Comet, with the exception of extensions that alter the new tab page.</p>
  </li>

  <li>
    <p><b>Standard Browser Features</b>: Comet includes all the common browser functionality you expect, such as pinned tabs, bookmarks, page translation, autofill, and password suggestions.</p>
  </li>
</ul>

<h2 id="h_8e146250c5">What makes Comet different from other Chromium browsers?</h2>

<p>While Comet is built on the Chromium foundation, it adds several unique AI-powered features:</p>

<ul>
  <li>
    <p><b>Perplexity AI Integration</b>: Comet uses Perplexity as its primary search engine, providing access to accurate, verified information instantly.</p>
  </li>

  <li>
    <p><b>Personal Search with Comet Assistant</b>: Leverages your browsing history and AI-driven web navigation to retrieve and analyze information on your behalf.</p>
  </li>

  <li>
    <p><b>Built-in AI Assistant</b>: Access the sidebar to summarize page content, verify information, find related content, and perform translations.</p>
  </li>

  <li>
    <p><b>Integrated AdBlock</b>: Built-in ad blocking for a cleaner browsing experience.</p>
  </li>
</ul>
