Is Perplexity Comet the Best Browser For Investors?
How to research stocks and trigger workflows all in one browser without switching tabs
I recently got access to Perplexity Comet and I’ve been using it every day since. I can't stop experimenting!
This isn’t just another browser. It’s like having your own personal assistant while browsing the web. No extra tabs, add-ons, or apps needed. Just ask, and it gets the job done using natural language.
What is Perplexity Comet?
Comet is Perplexity’s new AI-powered browser, which uses the Perplexity search engine and comes with a built-in AI assistant. It can do much more than a chatbot, enabling actions across multiple tabs and platforms, and more importantly, all in one place.
Note: It’s currently available to Perplexity Max subscribers and via Invite-only access
Let's look at some real world use cases of how Comet can streamline stock research and analysis.
Managing Stock Watchlist
As I have already shared on X, I asked Comet to go through my watchlist of stocks and list Swiss companies affected by the US's recent 39% tariff drop.
Within few minutes, I got a list of stocks that are affected by the recent US tariffs along with a quick explanation. You can even ask it to highlight certain rows, add additional details, and much more.
Summarizing Content
When it comes to natural resources, Goehring and Rozencwajg’s commentaries and podcast are among my favourites. While reading their latest Q1 2025 market commentary, I asked Comet to summarize, extract key insights and list all commodities and companies mentioned.
Reddit is one of my go-to platforms for deep and no-fluff discussions about stocks. With Comet, I don’t even need to bookmark posts anymore. I just asked it to find the most upvoted Reddit post, open it in a new tab, and summarize it.
To take it further, I could ask Comet to add some of new stock picks to my watchlist in Google Sheets right in my browser. No tab switching, no copy-pasting.
That’s exactly what I tested next to see how Comet can take full control of the browser.
Scheduling Calendar Events
This one really surprised me. I asked Comet to look up upcoming earnings report dates for Palantir, MercadoLibre, and AMD, and to create calendar events for each with a 1-hour reminder before the event.
All three events were added to my calendar without me lifting another finger. (Video shortened for the sake of time)
Analyzing News Sentiment
While researching about Novo Nordisk lately, I asked Comet to check how the stock is being talked about across media and to list me the co-mentions.
It returned sentiment insights and a list of companies mentioned alongside Novo, like Eli Lilly and Hims & Hers.
Conclusion
With Comet, almost anything can be accomplished within a single browser window. While it is far from perfect, like the depth of the results in some cases, its agentic web experience goes beyond simple search by transforming web interaction with task automation and deep research tools.
There’s definitely a lot more to explore, which I’ll cover in the upcoming posts.
Thank you for reading. Hope you have an awesome week!
You can always support my work by buying me a coffee (or two😉). Thank you🙏
