How to Set Up and Use Perplexity Comet AI Browser (Step-by-Step Guide)

You may have noticed that browsers are no longer the same. Literally, all browsers have integrated artificial intelligence (AI) to make it easier for users to find relevant information. You no longer need to open 30 tabs to research one decision; you can do a single thread of conversation. Perplexity AI, known as a free AI-powered answer engine that provides cited answers, has launched its very own AI browser known as Comet.

What is Perplexity Comet?

Perplexity's Comet is not just a regular browser; it is designed to be your personal AI assistant that happens to live within your browser, helping you streamline workflows and act as a "thinking partner."

The goal is to let the AI handle the tasks that may be important but not a priority, yet they need to be done, even though it can be time-consuming. Instead of you working for the browser, opening tab after tab, the browser is designed to work for you. It can automate tasks that usually require manual input, such as filling out forms, clicking through checkout processes, and submitting information.

Key features of Perplexity Comet that you should know:

• Unified AI across the web: Comet combines AI search, page-aware context, and automation inside the browser. Summarize articles, translate passages, compare products, or stitch together research without leaving the site you're on.
• Agentic task help: With Comet Assistant, you can let the AI agent automate your tasks like research, shopping, form filling, playing games, and even stepping through unfamiliar SaaS interfaces.
• Workday copiloting: You can ask Comet to summarise emails, schedule meetings, brief you for the day, and pull context from Slack or social feeds; it's designed to answer questions about your inbox and calendar rather than just search the web.

How to set up and use Perplexity Comet AI Browser:

Step 1: Visit this Perplexity Comet page and click on Get Comet to auto-download the AI browser. It is very lightweight (13.2 MB).

• Once you finish downloading, open the file to install the browser on your PC.

• It will take a few seconds to install the browser.

• Once it finishes downloading, you can launch it instantly.

Step 2: It will show some beautiful animations after which you can get started with it.

• Now, to fully turn this AI browser into your personal assistant, you can import your entire Google profile (browser history, settings, bookmarks, and passwords) to get the best experience. Or you can skip that part and do it later.

• After that, do some personalization by choosing a username and avatar. Avatar options include (the sun, our moon, and all 8 planets).

• Finally, complete the final step.

Step 3: You are now inside Perplexity Comet. The user interface is exactly like that of the Perplexity web app, which is probably because it keeps things simple for users.

At the bottom, you have three options:

• Try Assistant: It shows different ways you can use the Comet Assistant to automate your work.

• Edit Widget: This is my favourite feature as it lets you decide what main features you want easy access to. My personal favorites are the clock, Wormhole, Zen mode, and Comet assistant in action.

• Invites: This to invite your friends, family, and colleagues to try Comet.

You also have instant access to Comet Assistant, Voice mode, and web page summary on the top right.

Step 4: You can instantly start using Comet to find information and get information exactly how you would on the Perplexity web app (short and cited).

Step 5: You can also use the Perplexity assistant to automate tasks for you, such as researching, summaries, shopping, and more. Comet tasks control over the browser to read, scroll, and write. It is decently fast, but it can be faster.

I made a simple request, which you can try yourself too:

• Open aitoolsclub.com
• What was the last published blog on this website?
• Summarize it for me.

What makes Comet compelling is its attempt to create a more cohesive and intelligent browsing experience.

• Even someone with zero technical background can use it right now to reduce the daily friction of online life.
• For the technical user, it acts as a powerful agentic assistant for research and productivity, capable of quickly navigating complex software documentation or summarizing dense technical papers.

The browser can be a productivity boost for anyone who spends a significant amount of time online, whether for personal or professional purposes.

A necessary caution:

Although it is not specific to Perplexity, powerful agentic features have increased security risks. Independent audits from Brave and Guardio highlighted scenarios where Comet could be steered by malicious "prompt injection" on webpages or could be led to phishing schemes. These risks are higher because automations use the user's permissions while they are logged in.

Until there are proven mitigations, enterprises are recommended to test the agentic feature with strict policies, limit sensitive scopes, and keep "human-in-the-loop" for high-risk actions.

In Conclusion:

Perplexity AI made a bold move by launching its own browser after making an offer to buy Google Chrome for $34.5 billion. Comet is unlike any other browser we are used to; it incorporates an AI assistant that reads, reasons, and acts alongside you. In practice and under perfect circumstances, that means faster decisions, smoother workflows, and less jumping between tools.

The flip side is trust: automations must be transparent and manageable while not falling into malicious "prompt injection" or phishing schemes. For researchers, analysts, and teams constantly on the web, Comet is already worth a trial, as long as you pair its speed with sensible guardrails.
