Amazon has threatened Perplexity with legal action after its shopping tool was accused of computer fraud.
On Tuesday, the startup’s Comet AI was accused of violating Amazon’s ban on robot and data gathering.
Amazon has previously warned Perplexity about the use of the tool on its shopping site.
In the claim, Amazon accused Perplexity of misconduct against its company’s terms of service, claiming that its agentic browser, Comet AI, was being used to access customer accounts and make automated purchases on behalf of a customer, without Amazon’s knowledge.
The accusation also claims that perplexity has damaged Amazon’s customer experience by pretending to be a human consumer and accessing restricted sections of its website, threatening the trust and privacy of customers.
In a statement on Tuesday, a spokesperson for Amazon addressed the claims made against Perplexity.
They said:
“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.
“This helps ensure a positive customer experience and it is how others operate, including food delivery apps and the restaurants they take orders for, delivery service apps and the stores they shop from, and online travel agencies and the airlines they book tickets with for customers.
“Agentic third-party applications such as Perplexity’s Comet have the same obligations.”
Amazon had previously demanded that Perplexity stop using its shopping tool bots on its platform in November 2024; however, it later accused the company of breaching this request in August 2025.
In response to the allegations, Perplexity published an article on Tuesday titled ‘Bullying is Not Innovation’.
Within the article, the company responds to the claims made against them, saying they have felt ‘bullied’ by Amazon’s attempts to block Comet AI.
A spokesperson for Perplexity said:
“This week, Perplexity received an aggressive legal threat from Amazon, demanding we prohibit Comet users from using their AI assistants on Amazon.
