The New York Times is suing generative-AI startup Perplexity for copyright infringement, expanding its legal fight against artificial-intelligence companies that it says steal and then profit off its content.

In its lawsuit, the Times accused Perplexity of illegally crawling its material and repackaging original Times stories in “verbatim or near-verbatim” written responses to users. It also accused the company of copyright infringement for its videos, podcasts and images, and of fabricating information and falsely attributing it to the Times.

The Times also said Perplexity’s Comet AI assistant, which can browse the web and complete tasks for users, produced detailed summaries of Times articles.

“Perplexity has violated the protections that intellectual property law provides for The Times’s expressive, original journalism,” the Times said in its suit, which was filed in a New York federal court.

The publisher is seeking damages and injunctive relief, including removal of Times content from Perplexity’s products.

The Chicago Tribune also filed a suit against Perplexity for copyright infringement, on Thursday.
