Perplexity AI accused Amazon of “bullying” on Tuesday after it received a letter from the e-commerce giant demanding it prevent people from using its artificial intelligence browser Comet to make purchases on their behalf.
In a blog post, Perplexity said users can ask its Comet Assistant to find items and make purchases on Amazon, and that they “love this experience.” But Perplexity said it received “an aggressive legal threat” from Amazon “demanding” that it put a stop to that practice.
Amazon has already taken steps in recent months to prevent external AI agents from crawling its website, including those developed by OpenAI, Google and Meta.
“Amazon should love this. Easier shopping means more transactions and happier customers. But Amazon doesn’t care,” Perplexity wrote. “They’re more interested in serving you ads, sponsored results, and influencing your purchasing decisions with upsells and confusing offers.”
In a blog post, Amazon said in a statement that third-party shopping agents should operate openly and “respect service provider decisions” on whether or not to participate. It pointed to food delivery, delivery service and online travel agencies as examples of applications that operate in a similar manner.
“Agentic third-party applications such as Perplexity’s Comet have the same obligations, and we’ve repeatedly requested that Perplexity remove Amazon from the Comet experience, particularly in light of the significantly degraded shopping and customer service experience it provides,” the company wrote.
At the same time that Amazon is seeking to keep AI tools off its site, the company has launched its own offerings.
Last February, it rolled out a shopping chatbot called Rufus that can answer questions and suggest products. Amazon also began testing an agent in April called “Buy For Me” that lets shoppers purchase some products from other websites without leaving its app.
Perplexity is best known for its AI-powered search engine that gives users simple answers to questions and links out to the original source material on the web. The company initially launched Comet in July, and it rolled out for free worldwide in October.
Comet is supposed to serve as a personal assistant that can search the web, organize tabs, shop, draft emails and more, Perplexity said.
