Amazon has sent a written a cease-and-desist letter to Perplexity, warning the AI startup to immediately stop deploying its AI agent Comet to scrape the tech giant's e-commerce websites.
"Perplexity does not have authorization to access Amazon’s Store, Amazon user accounts, or account details, using its disguised or obscured Comet AI agents," as per the letter.
Amazon stated that Perplexity has refused to operate transparently and has instead taken affirmative steps to conceal its agentic activities in the Amazon Store.
The letter also claimed that Perplexity's Comet AI degrades the shopping experience of customers. It explained that when the AI agent buys from Amazon Store, it may not select the best price, delivery method, or recommendations. Amazon added that the AI startup may put the security of customers at risk.
It further said that Perplexity’s misconduct has caused significant losses, and entitles Amazon to injunctive relief and considerable damages.
In response, Perplexity has termed Amazon's letter as a "threat to all internet users".
“This week, Perplexity received an aggressive legal threat from Amazon, demanding we prohibit Comet users from using their AI assistants on Amazon. This is Amazon’s first legal salvo against an AI company, and it is a threat to all internet users,” said Perplexity in a blog post.
A few months ago, Cloudflare published research accusing Perplexity of scraping websites that had blocked AI chatbots.
Last week, Perplexity signed a global multi-year licensing agreement with Getty Images that will allow the AI startup to display images of visual content creator and marketplace across its search and discovery tools.
