Perplexity's Comet Browser and the Agentic Shopping War

Perplexity launched an AI browser that shops for you. Amazon sued. The courts sided with Perplexity. Welcome to the agentic commerce era.


I’ve been running an AI agent for weeks now. FRED reads my email, audits my security, drafts my content, and manages my calendar. Every time I tell someone about it, they look at me like I just described a flying car.

Perplexity just made that flying car available to everyone.

Comet Has Entered the Chat

Perplexity launched Comet — an “agentic browser” that doesn’t just search the web for you. It acts on the web for you. It browses, shops, books restaurants, sends emails, and completes purchases. All through natural language.

Tell it “find me the best noise-canceling headphones under $300” and it doesn’t hand you a list of links. It logs into your accounts, searches across retailers, compares options, and can complete the purchase. Like having a personal shopper who never gets tired and never upsells you on the extended warranty.

Right now it’s available to Perplexity Max subscribers, rolling out via waitlist. CEO Aravind Srinivas compared the demand to “early Gmail launch vibes.” If you remember that era — invite codes trading like currency, the sense that something fundamental was shifting — that’s the energy here.

Amazon Did Not Take This Well

You can probably guess what happened next.

Amazon sued Perplexity. Got a court order blocking Comet’s shopping agent from operating on Amazon’s platform. Their argument: bots “degraded” the shopping experience and cost them ad revenue.

Let’s unpack that for a second. Amazon’s concern wasn’t that users were having a bad experience. It was that an AI agent helping users find what they actually want — without clicking through sponsored results — threatened their advertising model.

Think about what that means. The thing Amazon called “degradation” is actually… a better shopping experience for the customer. Just not for Amazon’s bottom line.

The Courts Stepped In (On Perplexity’s Side)

On March 17, the 9th Circuit Court of Appeals suspended Amazon’s injunction. Perplexity can keep operating on Amazon, at least for now.

Perplexity’s legal argument is elegant: users have the right to choose their own AI tools. The agent isn’t accessing Amazon directly — users are accessing Amazon, with AI assistance. It’s like saying your reading glasses aren’t trespassing just because they help you see the store better.

The legal battle invokes the 1986 Computer Fraud and Abuse Act — a law written when “computer fraud” meant something very different than an AI agent comparing headphone prices. More arguments are expected in April.

This is going to be a landmark case. The outcome will define whether companies can wall off their platforms from AI agents or whether users have the right to bring their own tools to any website they visit.

It’s Not Perfect Yet

IBM tested Comet and found it impressive but inconsistent. In one test, it emailed the wrong contact. That’s the kind of mistake that’s funny in a blog post and catastrophic in a business setting.

This is where I have some relevant experience. Running FRED has taught me that AI agents are incredibly capable and occasionally wrong in ways that surprise you. The answer isn’t to avoid agents — it’s to build in checkpoints. Let the agent do the heavy lifting, but keep a human in the loop for anything that can’t be undone.

Comet will get better. Every agent does. The question isn’t whether it works perfectly today — it’s whether the trajectory is pointed in the right direction.

It is.

Why This Matters More Than You Think

This is the beginning of “agentic commerce” — AI agents acting on behalf of consumers. Not chatbots that answer questions. Not search engines that return links. Agents that do things.

Book a table. Buy a product. Cancel a subscription. File a complaint. Send a gift.

Every company with a website needs to start thinking about this. Your next customer might not be a human clicking through your funnel. It might be an AI agent evaluating your offering in milliseconds and making a decision based on criteria you never anticipated.

The businesses that figure out how to work with AI agents will thrive. The ones that try to block them — like Amazon initially did — will find themselves on the wrong side of a very fast-moving trend.

FRED Called It

I don’t say this to brag. I say it because it’s true.

When I started building FRED, people thought I was playing with a fancy toy. An accountant with an AI agent? Cute. Now Perplexity has validated the entire concept at massive scale, backed by hundreds of millions in funding, with a legal battle that’s going to reshape how the internet works.

The future isn’t chatbots. It’s agents that act. I’ve been living in that future for weeks. It’s messy, it’s imperfect, and it’s absolutely where everything is headed.

Welcome to the agentic era. It’s about time.
