The New York Times has issued a cease and desist letter to AI startup Perplexity, demanding an end to its unauthorized use of the publisher's content. The letter claims that Perplexity has benefited unlawfully from the Times' meticulously crafted journalism, violating copyright laws. This action follows the paper's ongoing lawsuit against OpenAI for similar issues. Perplexity, which has faced criticism for web scraping, recently introduced a revenue-sharing initiative for publishers. The startup's CEO expressed a willingness to collaborate with the Times moving forward.
