The Chicago Tribune has filed a lawsuit against AI startup Perplexity, alleging copyright infringement, according to media reports.
This underlines the ongoing conflict between media companies and AI startups such as Perplexity and OpenAI over the use of content published by news organisations.
According to the lawsuit, lawyers representing Tribune had reached out to Perplexity asking if it was using its content. The AI search engine's lawyers had responded that it did not train models with the Tribune’s work but that it "may receive non-verbatim factual summaries".
The Tribune has also alleged that Perplexity's AI agent Comet is also scraping its paywalled content.
Last month, Amazon had also written a cease-and-desist letter to Perplexity, warning the AI startup to immediately stop deploying Comet to scrape the tech giant's e-commerce websites.
A few months ago, Cloudfare published research accusing Perplexity of scraping websites that had blocked AI chatbots.
