Amazon and Perplexity Clash Over Access and Identity of AI Shopping Agent Comet
Amazon sends a cease-and-desist letter to the AI startup Perplexity because its "agentic browser" Comet doesn't identify itself as an automated agent, which goes against Amazon's rules. The argument sparks a big discussion about user choice, AI transparency, and the future of online shopping.

Introduction
The field of artificial intelligence is changing quickly. It is moving from simple chatbots to powerful "agentic AI" systems that can do complicated, multi-step tasks for a user across the web, like booking travel, managing emails, and, most importantly, shopping online.
Perplexity AI is a startup that stands out in this new field because of its advanced conversational search engine and its newest product, the Comet AI-powered web browser and shopping assistant. Comet is meant to make the online experience easier by letting users give the AI a simple command, like "buy me the best-rated coffee maker on Amazon." The AI will then do everything from browsing to comparing to making the purchase.
But the quick rise of this agentic technology has led to a direct and public fight with one of the biggest e-commerce sites in the world. This article talks about the legal fight that is starting between Amazon and Perplexity over the Comet shopping agent. This fight raises important questions about user rights, platform control, and the rules that AI agents need to follow when they work on the open web.
Amazon’s Legal Salvo: Breach of Platform Rules
Failure to Disclose: Amazon says that Perplexity's Comet shopping assistant breaks platform rules by not clearly stating that it is an automated agent when it makes purchases or browses for a user.
Terms of Use The company says that all automated tools used to gather information or make purchases must clearly identify themselves to ensure transparency and a good customer experience.
Amazon said that other third-party digital services that act on behalf of users, like apps for booking travel or food delivery, already tell businesses who they are when they work with them.
Amazon confirmed the move and said that the legal warning came after several other warnings that were ignored. The online retail giant said that Perplexity could keep going if it correctly identified its AI tool. It also hinted that it might block similar agents in the future.
The CEO Speaks Out
"We would be happy to work together with Amazon to figure out a win-win outcome for both us and them. But attempts to block our Comet Assistant on Amazon and hurt our users -- we will have to stand up for them and not get bullied by Amazon.” — Aravind Srinivas (@AravSrinivas)
The company backed this up with a blog post called "Bullying is not innovation," which called Amazon's action its first official legal attack on an AI company and a bigger "threat to all internet users."
Perplexity's Core Arguments: Agency, Choice, and Business Models
Perplexity strongly disagrees with Amazon's argument, saying that the lawsuit is more about protecting the market than the integrity of the platform.
Perplexity's Main Defense:
User's Extension: Perplexity says that Comet only does what a human user tells it to do, which means that the AI has the same permissions as a person using a web browser.
Protecting User Choice: The company thinks the move is an attempt to limit user choice, and they are fighting for people's right to use their favorite AI assistants for shopping.
Accusation of Protecting Ad Revenue: The AI startup said that Amazon's real goal is to protect its business model, which is based on ads. Automated shopping bots skip over sponsored listings, which cuts into Amazon's potential sales.
Against Corporate Control: Perplexity said that Amazon wants to "take away user rights" so that it can keep control over how products are seen and paid for.
Broader Concerns: The Ethics of AI Web Practices
This fight shows that there is still a lot of disagreement about how agentic AI should work with established online platforms.
Cloudflare Scrutiny: This fight comes after web security company Cloudflare accused Perplexity of scraping website data despite rules against it. Perplexity said that it only went to public sites when users asked it to, just like a human browser. Cloudflare, on the other hand, said that identity masking was used.
The Argument About Openness: The main point of disagreement is whether an AI agent working for a user needs to make a separate declaration. Amazon wants everything to be clear, and they point to other third-party agents that are open about their automation. Perplexity says that it shouldn't have to go through different checks because it works for the user.
As AI agents get better at handling complicated tasks, this fight between Amazon and Perplexity is setting an early example of how AI-powered apps will be able to work on the internet in the future.
What Does This Mean for the Future of AI?
The fight between a tech giant and a top AI innovator is a key moment for the future of online shopping. As AI agents like Comet get better at making decisions and doing transactions for users, the main question becomes more important: Should these assistants have to clearly identify themselves as automated agents when they work on e-commerce sites, or should they have the same rights as a human user since they only do what the user tells them to do?
Frequently Asked Questions:
1. What is Perplexity’s Comet AI assistant?
Perplexity made Comet, an AI-powered browser and shopping assistant. It can look at websites, compare products, and buy things for a user based on commands like "Find the best deal" or "Buy this item."
2. Why is Amazon objecting to Comet’s use on its platform?
Amazon says that any automated system that interacts with its site must make it clear that it is not a person. Amazon says that Comet doesn't tell people this, which goes against the rules for transparency and user experience on its platform.
3. What could this conflict mean for future AI browsing and shopping tools?
This argument could set a standard for how AI agents can interact with websites. Depending on what happens, platforms may need to make AI agents follow stricter rules about what they can and can't do, or AI systems may be given more freedom to act on their own.
