Only one day after the Center for Investigative Reporting filed a copyright lawsuit against Perplexity, The New York Times commenced a similar action in federal court. 

The Times suit alleges that “Perplexity provides commercial products to its own users that substitute for The Times, without permission or remuneration,” the Times reports.

In some cases, Perplexity grabbed entire Times articles, the paper contends. 

In addition, the Times charges that Perplexity’s search engine made up information, so-called hallucination, and attributed it to the Times, it continues. 

On Thursday, The Chicago Tribune Co. and MediaNews Group filed suit, alleging that Perplexity is unlawfully using the Tribune’s content to build its AI-driven search engine.

The complaint charges that Perplexity promotes itself as “an intelligent research assistant, streamlining your information gathering by delivering the precise knowledge you need without the extra steps and clicks.”

Perplexity’s legal team apparently has plenty of work cut out for it. Dow Jones, Reddit and several overseas publishers have also sued the company.
