My Early Impressions of the Perplexity Comet Browser

Most people outside of Twitter/X don’t know what the @PerplexityComet Browser is. Last night, I spoke with one of my professors and introduced him to this impressive product. To show what it can do, I quickly recorded a demo video

To show what it can do, I quickly recorded a demo video 🎥:

1️⃣ It controlled my LinkedIn page and scrolled through it to summarize the information.

2️⃣ It sent Professor Eduardo Bailetti a direct message.

This agentic browser can take actions on your behalf 🤖.

I was fortunate to join the early beta test of Comet Browser in May. At first, I dismissed it as just another Chrome wrapper with Perplexity as the default. 🙄But over the past month, I realized that Comet can actively control my browser, which completely changed my opinion. I now see it as one of the most promising products available.

Compared to ChatGPT Agent mode, which runs on a virtual computer, Comet lets me log into any of my accounts and helps me get things done. It feels like a true general-purpose agent 🔥. However, its running time—or context window—is still much shorter than that of ChatGPT Agent mode. Hopefully, with more powerful open-source models, this will improve quickly.

Comet also positions Perplexity well in the market, especially since large companies tend to move slowly when dealing with privacy and related issues.

One interesting use case is to use Comet to search on Rednote, one of the most popular Chinese social media platforms. It bridges the gap of isolated “information island”.

(Background: Chinese social media platforms operate in silos, so you can’t easily access data across them through a single API outside.)

(P.S. Although I had some arguments with one friend, I still believe Comet is an excellent product. People like me can learn from Perplexity team’s skillful use of these technologies, even though they don’t own foundational models.)
