Let's be honest: it's easy to be skeptical about the hype surrounding AI browsers. But after using Perplexity Comet for a full week, the skepticism is gone. This isn't just a different way to search the web; it's a completely different way to interact with it.
I've tested it against Dia, Google Chrome with Gemini, and ChatGPT's agent mode. The difference? Comet doesn't just read the web—it takes action on it. It clicks buttons, filters results, and monitors pages so you don't have to.
From finding promo codes that actually work to automating tedious clicks on podcast dashboards, here is a look at how Comet changes the game. Let's dive into the use cases.
This is the feature that immediately sets Comet apart. We've all been there—searching sketchy coupon sites, copying codes, and getting rejected at checkout. Comet automates this entire frustrating loop.
Unlike ChatGPT, which might just list codes it found, Comet can actually see the discount field in your cart and test the codes for you live.
It can run in the background while you open a new tab to do real work. In our tests, it found a working code in seconds, while other AI agents spent over 11 minutes just looking for lists.
YouTube is a goldmine of information, but finding specific moments in long videos is a pain. Comet turns YouTube into a searchable database.
You can ask it to find a specific quote—like the exact second Neil Armstrong said "one small step"—and it won't just tell you the timestamp. It will open the video and start playing right at that moment.
This might be the most niche but powerful feature: Comet can baby-sit a webpage for you. If you are waiting for a button to become clickable or a status to change, you don't have to sit there refreshing the page.
For example, in Apple Podcasts Connect, you often have to wait for audio to process before you can hit Publish. With Comet, you can use a prompt like: "Refresh this page every minute until the publish button becomes clickable, then click it."
It handles the refreshing and the clicking while you walk away.
Navigating government websites or dense analytics dashboards is rarely fun. Comet simplifies this by acting as an interpreter for complex pages.
If you are looking at a dashboard like YouTube Studio or a podcast host, you can ask plain English questions about the data on the screen.
Pro tip: If you find yourself using the same prompts over and over, use a tool like TextExpander to save your best Comet prompts. A quick keyboard shortcut can trigger a complex automation.
Perplexity Comet isn't perfect—it struggled pretty hard when we asked it to play a game of Wordle. But for real-world tasks, it is incredibly capable. It changes the browser from a passive window into an active assistant.
Whether you are formatting data or just trying to save a few dollars on a purchase, it's worth taking for a spin. Give it a try and see what workflows you can automate.
