Perplexity, which provides an AI “answer” engine along with the AI browser Comet, is accused of ignoring CNN’s efforts to “identify or block Perplexity’s unknown crawlers” to remove the content. “People describe, research, write, edit, and create content that Perplexity takes without permission or compensation,” the lawsuit says.
According to the lawsuit, CNN says it wants to provide the content through Perplexity’s Comet Plus subscription in October 2025 “It did not result in a final agreement between the parties due to the inability to agree on a number of issues, including the limitations on Perplexity’s use of CNN’s content in its user response.” CNN terminated the contract in November and later wrote a letter to Perplexity, demanding that it stop using its content and trademarks without permission. Bewildered, she said she did not respond.
CNN is seeking damages and a permanent injunction against Perplexity’s allegedly illegal practices. Asked for comment, Perplexity spokesman Jesse Dwyer said, “You can’t copy facts.”
