Perplexity Comet Browser Features & Capabilities 2025
Most browsers are built around one philosophy: give you a blank bar and let you do the heavy lifting. You type, you click, you organize, you remember. The Comet Browser, introduced by Perplexity, flips that expectation. Instead of treating browsing as a passive tool, it tries to become an active partner in how you use the web.
That simple shift—moving from you drive, browser follows to browser co-pilots with you—is what makes Comet stand out. In this article, we’ll look at its features (the tools built into the browser) and its capabilities (the real things it can do for people).

Features That Define Comet Browser
Features are the bones of the browser. They’re what you see, click, and configure. Unlike surface-level browsers that repeat the same tab, bookmark, and history patterns, Comet includes a fresh toolkit that feels designed for 2025 needs, not 2010 habits.
1. An AI Sidebar That Never Interrupts
Instead of opening a new tab or pop-up, Comet’s AI lives quietly in a sidebar. Highlight a line in a research paper, and it offers a simplified version. Reading an article on tax law? The sidebar can translate legal jargon into plain English.
The magic is not that it’s “an AI assistant”—lots of tools claim that—but that it is contextual. It doesn’t just answer “What is X?”; it knows you’re asking inside the frame of the page you’re on.
That means the difference between this:
- Chrome user: copy, open ChatGPT, paste, reframe, switch back.
- Comet user: highlight, ask, get answer without losing the page.
It seems small, but the saved friction adds up after hundreds of queries.
2. Memory That Works Like Human Recall
Bookmarks are fine, but nobody remembers to actually organize them. Comet introduces what feels closer to a human memory system. It doesn’t just save URLs; it remembers why you visited.
Example: if you searched for “budget travel in Spain” last month, Comet can resurface those exact sources when you ask again—even if you never hit save. It remembers by intention, not by folder.
This memory-driven browsing is a feature you won’t find in Firefox, Edge, or even Chrome’s latest updates.
3. Task Chains (Multi-Step Automation)
Where Chrome has “extensions” and Safari has “shortcuts,” Comet introduces Task Chains. These are step-by-step flows you can design or let the AI design for you.
Imagine you’re comparing laptops for under $1000:
- Open Amazon, BestBuy, and Newegg.
- Pull only models with 16GB RAM and SSD.
- Summarize reviews into pros/cons.
- Export into a Google Doc.
With Comet, that’s a single Task Chain. Instead of you repeating those clicks and filters across sites, the browser executes it.
This feature moves Comet away from “browser as a container” toward “browser as an agent.”
4. Split-View Reading Mode
Research often means juggling tabs. Comet offers split-view tabs, letting you open two or three articles side by side without external tools. Pair that with AI summarization, and you can quickly compare sources without endlessly switching windows.
This may sound minor, but anyone writing papers, creating reports, or analyzing data knows how revolutionary this is.
5. Local AI Mode
Most AI-powered tools demand cloud access. Comet includes a local inference mode for certain tasks. That means if you’re offline (say, on a train) or you don’t want data leaving your laptop, Comet can still summarize PDFs, rewrite notes, or search your stored history.
Privacy and functionality rarely sit in the same box, but here they do.
6. Learning Profiles
Instead of one-size-fits-all browsing, Comet builds profiles tuned to your needs:
- Research Mode – keeps deeper memory, recommends citations.
- Casual Mode – discards AI history, focuses on fast loading.
- Developer Mode – integrates with GitHub and documentation scraping.
These profiles aren’t gimmicks; they actually shift how the AI processes information, making the browser feel less generic and more like your personal tool
Capabilities: What You Can Actually Do With Comet
Features are “what it has.” Capabilities are what those features empower you to do. This is where Comet differentiates itself—because its capabilities expand beyond “faster browsing” into new workflows entirely.
1. Turn Research Into Ready Notes
Instead of opening ten tabs and creating messy Word files, Comet can gather articles, extract the key points, and generate organized notes. Students can ask, “Give me 5 arguments for renewable energy and their sources,” and get a structured outline within minutes.
This doesn’t eliminate thinking—but it drastically reduces the grunt work of sorting through repetitive content.
2. Act as a Negotiator With Information
Say you’re planning a trip. You want the cheapest hotel within walking distance of a conference center. Normally, you’d:
- Check five booking sites.
- Open Google Maps for distance.
- Manually compare results.
Comet can do that in one request: “Find me hotels under $120 within 10 minutes walking of Hilton Midtown, NYC, and rank by reviews.”
That’s not just browsing; that’s outsourcing negotiation with the internet.
3. Build Instant Briefings
Professionals no longer have to scroll through pages of news. Comet can generate daily briefings filtered by relevance:
- A doctor can get updates on medical journals.
- A lawyer can track regulatory changes.
- A marketer can pull competitor campaigns.
These aren’t generic Google News feeds—they’re personalized digests built directly in the browser.
4. Teach You While You Work
Unlike passive search, Comet can act as a tutor. If you’re coding and hit an error, highlight it, and the sidebar explains not just the fix but the concept behind it. Over time, the browser isn’t only helping you finish tasks—it’s teaching you skills.
That’s a leap beyond productivity; it turns the browser into an educational companion.
5. Collaboration in Real Time
Comet allows you to share AI sessions with others. A student group can collectively build a literature review inside the browser. A project team can run research together without emailing scattered notes.
This “shared browsing intelligence” is something traditional browsers don’t even attempt.
6. Reduce Digital Exhaustion
Endless tabs, endless clicks, endless scrolling—it’s exhausting. By automating repetitive steps and focusing attention only where it matters, Comet helps reduce the decision fatigue of browsing.
The capability here is subtle but powerful: instead of you being a web janitor cleaning up after your own clicks, the browser handles much of the mess.
How Comet Browser’s Features and Capabilities Differ from a Normal Browser
Most web browsers are built for one main job: to open websites quickly. They give you bookmarks, history, extensions, and sometimes a private mode. But apart from speed, they don’t really do much else. Comet Browser is different because it is designed not only to open pages but also to help you work, learn, and save time while you are online.
A normal browser has a simple search bar. Comet adds an AI sidebar that can answer questions, summarize long articles, and even help you prepare notes while you are still browsing. Instead of opening many tabs and doing everything manually, Comet allows you to create task chains. This means you can set up a series of steps, like gathering information from different sites, comparing it, and preparing a draft, all inside the browser without switching back and forth.
When it comes to privacy, most browsers offer only incognito mode, which hides history but still sends data online. Comet includes a local mode where tasks are processed directly on your computer, keeping your activity more private. Another difference is that normal browsers treat every user the same, while Comet builds learning profiles. It slowly adapts to the way you browse and remembers what style of help you prefer, making the experience feel more personal.
Teamwork is also easier on Comet. A regular browser is made for one person at a time, but Comet has shared spaces where groups can research or work on a project together in real time. It also remembers what you were doing before by saving your sessions and keeping track of multiple tabs, so you can continue your work without starting from zero every time.
In simple terms, a normal browser just shows you web pages. Comet Browser helps you do something useful with those pages. For students, researchers, writers, and professionals, this can save hours of effort. Instead of being only a tool to reach the internet, Comet becomes a partner that helps finish the job.
Conclusion
The Perplexity Comet Browser is not just another browsing app. It comes with unique tools like the AI sidebar, task chains, local mode, and learning profiles—features that most other browsers don’t have yet. Its real strength is in what it can do, from automating research to helping teams work together online.
For a long time, browsers have only been seen as basic tools: fast, useful, and often forgettable. Comet changes that idea by acting more like a partner—it doesn’t just open websites, it helps you complete your tasks.
Whether Comet becomes the main choice for everyone or stays popular with a smaller group, one thing is sure: it changes the way we think about browsing. It shows that a browser can be more than a window—it can be a guide. And that is the biggest feature and capability of Comet in 2025.
