One significant feature is its replacement of Google Search results with the Perplexity AI “answer engine,” which appears directly in your browser when you input a query into the address bar. Unlike traditional search engines, Perplexity initially presents links to pertinent websites, followed by detailed information relevant to your query. Comet is useful for condensing search results, although it’s somewhat unsettling not to see the broad array of suggestions typically provided by Google.

Comet also features a built-in AI assistant, reminiscent of the Gemini integration Google is experimenting with in Chrome. By clicking the Assistant button in the browser’s top-right corner, you can access a sidebar with a chat interface. Here, you can enter queries or engage in voice conversations on varied topics, and even inquire specifically about the webpage you’re viewing.

Comet can generate a summary of an article, describe an image, summarize YouTube videos, or perform more research about a topic that catches your eye. It’s also able to scan all of your open tabs to provide summaries of those pages and compare products on them.

At this point, these are all pretty standard features for an AI tool, but what makes Comet really stand out is its ability to complete tasks on your behalf. After linking my Google account to the browser, I found that it was frighteningly fast at generating — and sending — an email to myself containing a summary of this year’s hurricane season outlook. The browser also speedily complied with a request to close all the tabs I hadn’t opened in more than 15 minutes. It even wrote and published a post on my X account on my behalf about the upcoming Made by Google event.

I asked it to unsubscribe from the promotional emails sent by Fubo and Fanatics.com as well. I watched as Comet’s AI assistant walked itself through the process. In the chat interface, Comet shows what it’s “seeing” as it locates recent emails sent by the companies, finds the unsubscribe button, and then actually selects it.

I even had Comet go through my list of LinkedIn invites and accept requests from people with five or more mutual connections. The browser once again traced its own process of going through my invites, identifying which ones met my threshold for mutual connections, and then hitting Accept. But as I had Comet perform these tasks, I couldn’t help but think it’d be faster if I did them myself.

It took Comet two minutes to unsubscribe from receiving emails from those two providers, but it only took me a little over 30 seconds to unsubscribe from the same ones (yes, I timed myself). Comet also ate up a chunk of time when accepting a couple of LinkedIn invitations, a task I could do in just a couple of clicks. I can see it serving as a great accessibility tool, as well as a way to complete tasks in the background while you’re doing something else.

You can unlock even more agentic features when you start a prompt with “take control of my browser.” I didn’t realize this until I contacted Perplexity to ask when the browser would be capable of booking reservations or buying products. Without this phrase, Comet will stop short of completing these tasks and instead provide instructions on how you can do it manually.

To start, I asked Comet to “take control of my browser” and summarize the comments on a Verge article. Instead of denying my request because it couldn’t read the collapsed comments section (like Gemini in Chrome did), Comet worked around this and opened the comments section itself. It summed up the sentiment surrounding my colleague Vee’s cursed piece about Grok’s AI anime waifu, calling users’ reaction to the chatbot overwhelmingly “negative and critical.”

I took things a step further by asking Comet to take control of my browser, add aquarium sand and glue for an iPad repair to my cart on Amazon, and then check out. The process was surprisingly seamless, as I watched it acknowledge the total price, choose Prime’s one-day shipping speed, select my default payment option, and hit “order” without needing me to intervene.

I only ran into some hiccups when having Comet book me a reservation for a restaurant. When I finally found a restaurant that accepts online reservations, I once again asked the browser to take control and make a reservation for me on a specific date. It completed the task, only it never asked for my email or phone number, and instead entered a generic placeholder for both. I was able to have Comet rebook with my actual email address, but it shows that the browser might not get everything right all the time.

“Some of the more complicated agentic actions like shopping do have a higher failure rate than simpler tasks, but this is actually a limitation of current AI models,” Perplexity spokesperson Jesse Dwyer told The Verge. “So this will only get easier and better in Comet.”

Still, Comet can do far more than Chrome’s Gemini integration, and it’s exactly the type of tool that Google has set its sights on creating. Perplexity CEO Aravind Srinivas has made it clear that the startup wants to challenge Google’s dominance, and Comet may play a big role in bringing it up to speed.
