Comet Browser Review: is Perplexity's AI browser worth switching to in 2026?

Comet is Perplexity's AI-native web browser, built on Chromium and centered around an assistant that can summarize pages, compare tabs, and attempt tasks on your behalf.

This comet browser review breaks down what it does well, where it falls short, and whether it makes sense to switch.

What is Comet browser?

Comet is a web browser developed by Perplexity, the AI search company. It runs on Chromium, the same open source engine that powers Chrome, Edge, and several other mainstream browsers, according to Wikipedia.

That shared foundation matters more than it sounds. It means Comet works with most of the sites you already visit, and it can pull in your bookmarks, passwords, and extensions from Chrome or Firefox in a couple of clicks.

What sets Comet apart isn't the tab bar or the address bar. It's the assistant sitting in the sidebar, built to act on the pages you have open rather than just answer questions about them in isolation.

Perplexity calls this "agentic browsing." In practice, that means you can ask the assistant to summarize an article, compare two open tabs, or attempt a multi-step task like clearing spam from your inbox, instead of doing it by hand.

Who this comet browser review is for

Reporting on Comet points to a fairly specific audience: people already comfortable with AI tools like ChatGPT or Perplexity's own search product, who want that familiarity extended into their everyday browsing.

It's less obviously aimed at someone who just wants a faster, simpler browser. If you rarely use AI chat tools now, the learning curve and the payoff may not line up.

Key features in this comet browser review

Comet Assistant

The Assistant lives in a sidebar rather than a separate pop-up window, which is a small but noticeable design choice compared to how some competitors bolt AI onto an existing browser.

It can read the page you're on, summarize long articles, and compare information across multiple open tabs at once.

For anyone doing research across several browser tabs, that's a genuinely useful shortcut.

Agentic task automation

This is the feature Comet is built around, and it's also the most inconsistent one. Documented testing found that Comet could handle simpler tasks, like clearing out a spam folder, without much trouble.

More complex tasks, such as adding ingredients from a recipe to an online shopping cart, tended to fail or stall. When it does work, it's often slower than just doing the task yourself.

Reports describe this as improving over time, though at the time of testing it was not reliable enough to depend on for anything time sensitive.

Voice assistant

Comet includes a voice mode, activated through a keyboard shortcut, that lets you speak commands instead of typing them.

Documented use found voice mode noticeably more limited than text mode. Asking the assistant to review a document's phrasing worked fine over text, but the same request through voice mode returned a message saying it couldn't access the page.

That gap between the two modes is worth knowing about before you rely on voice as your main way in.

Shortcuts

Shortcuts are reusable, prewritten prompts you can set up for recurring tasks, like checking for new job listings or pulling recipe ingredients off a page.

You choose the underlying AI model, what sources it should pull from, and how it should behave.

It's a genuine time saver for repetitive tasks, though it's worth being clear about what it isn't: shortcuts don't add new capability, they just automate the same things the assistant already does.

Email and calendar integration

Comet can connect to Gmail and Google Calendar with read and write access, letting the assistant answer questions about your schedule or draft replies to messages.

This is one of the features that leans furthest into the "assistant" framing rather than "browser," since it's acting on accounts outside the browser tab itself.

Homepage widgets and interface

The default homepage includes a small set of customizable widgets, a clock, a notes box, weather, and a few others, that you can add or remove.

The interface overall reads as more compact and slightly more modern than Chrome's, particularly in dark mode, though this is a matter of visual preference rather than function.

comet browser pricing and access

Access to Comet has changed over time, and the two most detailed sources reviewed here don't fully agree on the current state of it.

Earlier reporting described Comet as invite-only or gated behind a Perplexity Max subscription priced at $200 per month. Later coverage describes wider, free availability as part of a broader rollout strategy.

Given how quickly this has shifted, anyone checking access or pricing today should confirm current terms directly with Perplexity rather than relying on either account as fixed.

Separately, Perplexity offers Comet Plus, a $5 per month add on also bundled into Pro and Max subscriptions, that provides access to premium news content from outlets like CNN and The Washington Post.

According to TechCrunch, Perplexity made the core Comet browser free for everyone roughly three months after its initial Max-only launch, while Comet Plus remained a separate paid layer on top. This sits apart from core browser functionality and is closer to a content subscription than a browsing feature.

Performance and resource usage

Running AI features inside a browser has a real cost in system resources, and Comet is no exception.

Documented testing recorded CPU usage climbing to around 20 percent and memory usage exceeding 4GB across just a couple of tabs when the assistant was actively working.

During normal browsing, without the AI features engaged, resource usage was reported as roughly in line with Chrome.

In practice, this usually means the browser itself is fine for everyday use, and the AI layer is where the load shows up.

Privacy in this comet browser review

Comet stores several categories of data locally on your device by default: interaction data such as browsing history, technical data, extension data, settings, and communication data.

Keeping that processing local rather than sending everything to a third party server is a reasonable design choice from a privacy standpoint.

That said, Comet also uses this interaction data by default to personalize recommendations, a setting some users may want to review and adjust rather than leave untouched.

An EFF Cover Your Tracks test, which measures resistance to browser fingerprinting, returned an identical score for Comet and Chrome (18.12 bits of identifying information).

That puts Comet's baseline tracking resistance on par with, not better or worse than, a standard Chromium browser.

Search engine behavior

Perplexity is Comet's default search engine, and the address bar is built to accept full questions rather than just keywords.

That's convenient when you're asking something conversational, but less convenient for a quick keyword lookup, where Perplexity's results were reported as less consistent than Google's at surfacing the expected top link.

Comet does let you switch the default search engine to Google, Bing, or DuckDuckGo in settings, or force a one-off Google search by prefacing a query with "!g."

How to set up Comet browser

Installation

Comet installs from a downloadable file, roughly 200MB, with separate versions for Mac (.dmg) and Windows (.exe). On Mac, you may need to approve the app in system privacy settings the first time you open it.

Importing existing data

During setup, Comet offers to import bookmarks, passwords, browsing history, extensions, and settings from Chrome, Edge, Safari, or Firefox, which cuts down on manual setup considerably.

Choosing a default search engine

You can select Perplexity, Google, Bing, or DuckDuckGo as your default search engine during setup, and change it later in settings if needed.

Strengths and limitations

Strength	Limitation
Chromium base means broad site and extension compatibility	Inherits Chromium limitations, including restrictions on certain extensions
Fast, simple import from Chrome, Edge, Safari, or Firefox	Higher CPU and memory use when AI features are active
Sidebar assistant can summarize and compare tabs directly	Complex agentic tasks (like cart automation) are inconsistent
Local storage of collected data rather than third party servers	Data is used for personalization by default unless changed
Shortcuts automate recurring AI prompts	Voice mode is notably less capable than text mode
Fingerprinting resistance on par with Chrome	Default search engine (Perplexity) less reliable for direct keyword lookups

Is Comet browser worth it?

Reports from separate reviewers generally agree on the same shape of conclusion: the AI features are functional and occasionally genuinely useful, particularly tab summarization and comparison, but they aren't yet consistent enough to call transformative.

Where accounts differ is mostly on tone. Some framing treats Comet as a forward-looking, still-maturing product worth watching.

Other framing is more matter-of-fact, treating it as one AI browser among several competing for the same early adopter audience, without a clear standout advantage yet.

Teams evaluating browser switches for AI capability commonly report weighing agentic reliability against the friction of leaving a familiar setup, and that trade-off appears consistently in how Comet has been assessed.

Conclusion

Comet works as a standard browser and adds a capable, if inconsistent, AI assistant on top. It suits people already using AI tools daily. Casual users may not notice much difference from Chrome.
