If you read the first couple paragraphs it’s very self explanatory

The summary at the top is 3 paragraphs and not legalese at all.

"Amazon.com Services, LLC filed suit against Perplexity AI, Inc., an artificial intelligence company, asserting that Perplexity’s web browser tool, Comet, unlawfully accessed Amazon’s website in violation of [blah]. Perplexity’s Comet browser includes an AI “Assistant” that, when activated by a user, navigates Amazon.com on the user’s behalf, sending browser screenshots to Perplexity’s servers for further instruction. Amazon claimed that this use of the Assistant, despite their explicit prohibition, amounted to unauthorized access to its servers."
