US broadcasting giant CNN has filed a lawsuit against Perplexity AI, accusing the company of copying and reproducing its news content without authorisation to power AI-generated search responses.
The case, filed in a US federal court, adds to mounting legal scrutiny around generative AI firms and their use of copyrighted material from publishers.
CNN alleged that Perplexity used its journalism to create summaries and responses that compete directly with original news reporting, without licensing agreements or compensation.
The lawsuit comes as media companies globally push back against AI platforms over concerns about copyright, attribution and revenue loss.

CNN alleges AI summaries reproduced original reporting
According to the complaint, CNN claimed that Perplexity’s AI search engine reproduced portions of its reporting and presented them in generated answers, thereby reducing users’ need to visit the original publisher’s website.
The broadcaster argued that the startup benefited commercially from journalism produced with significant editorial investment while bypassing permission and licensing arrangements.
CNN is seeking damages and injunctive relief to stop the alleged use of its copyrighted material.
Perplexity, backed by major technology investors and increasingly positioned as a rival in the AI-powered search market, has faced criticism from several publishers in recent months over how its platform cites and summarises news content.
The lawsuit places renewed focus on how AI search engines source information and whether summarised outputs cross copyright boundaries under existing US laws.

AI firms face growing pressure from the global media industry
The legal action against Perplexity follows a broader wave of lawsuits and negotiations between media organisations and AI companies over content usage rights.
Publishers, including The New York Times and other global media groups, have raised concerns about AI models being trained on copyrighted journalism without consent.
Several companies are now pursuing licensing deals with AI developers, while others are choosing litigation.
Industry observers suggest that the outcome of these cases could influence how generative AI platforms access, train on and display news content in the future.
As regulatory and legal attention intensifies, the case is expected to become another closely watched development in the ongoing debate around artificial intelligence, copyright law and the future economics of digital journalism.
