Hands on with Perplexity's Comet Browser.

Holy cow, I just asked my computer to respond to and send an email for me and it did! No copy paste, no typing just asking it like I would an assistant.

I’ve been hearing tons of commercials for Perplexities Comet Browser and thought I would take a look at it. Comet is part of a emerging wave of AI-native browsers challenging Google Chrome's dominance. The concept of an agentic browser is awesome. You get a piece of software that can do things online for you.

Some examples:

1. Order Vanilla Ice Cream on Instacart from the Grocery Store.

2. Respond to my emails and ask customers to schedule time on calendar

3. Compare airline prices for flights from Philadelphia to Florida across multiple airlines and times.

The install and on-boarding experience were great! The Comet Browser was able to import bookmarks and passwords from my current browser and went right into a set of demo videos that showed how the Comet Agentic Browser works.

I have both Gmail based and Yahoo email accounts. Comet got locked up completely when I tried doing Yahoo email. However it did work with my Gmail account. This is likely because of the popularity differences between the two platforms.

Comet lacked what I would call Role Based Account Controls (RBAC) rules with emails but did have options on what you could allow it to do. It had some controls but could have had more granular options around Reading, Sending and other email features.

When sending my email, I chose to use voice mode because if I’m going to embrace an agentic world, this seems the best way to make use of it. If I’m manning the keyboard with my agent, I don’t think its going to be as big of a game changer as it could be if I can tell an assistant to go do some task and get back to me.

It took my voice commands well but oddly I had to press enter on the request.

I think it was still a bit buggy, and it may be because I didn’t ask Comet correctly.

Security Notes

Beware of "CometJacking". Comet can be tricked into actions like data exfiltration or other hacks and it was . I can imagine a scenario where the Comet Agent can be fooled into sending Instacart orders to the wrong address, poorly written emails or worse emails with proprietary or other data and there seems to be no limit to the pitfalls based on what you share with the agent.

Perplexity has since patched the initial CometJacking hole back in August, but it this issue highlights the risks in agentic AI features. Security minded individuals may be slow to adopt agentic browsers like Comet due to the AI's access to tabs and actions, though safeguards exist. Think with great power comes great responsibility. Is it worth the trade off to get your agentic browser to do tasks and save you time while potentially opening yourself to dangerous actions that can be taken by the agent.

In the Enterprise

I would suggest blocking this tool until:

1. It develops a bit more maybe 6 months or more.

2. Has better safeguards are in place to protect your data-driven.

3. You develop a strategy on which agentic browser you’re willing to support.
