Tuesday, Perplexity AI faced a class-action lawsuit in the U.S. District Court in San Francisco, accused of illegally sharing users' personal conversation data with Meta and Google through trackers. The lawsuit, initiated by a user from Utah, claims that Perplexity automatically downloads tracking tools after users log in to the homepage, allowing big tech companies to access sensitive interaction information, including financial and tax-related data, even when users are in "incognito mode."
In response to these allegations, a Perplexity spokesperson, Jesse Dwyer, stated that the company has not yet received the formal complaint. Meanwhile, Meta emphasized that its policies strictly prohibit advertisers from submitting sensitive data, while Google has not yet commented. At the same time, the AI industry is in a highly sensitive regulatory period. Meanwhile, competitors are also making headlines: Anthropic recently became the focus due to the strong performance of its new model "Claude Mythos" and an accidental leak of its source code, trying to present a more compliant image to challenge OpenAI's market dominance. In contrast, OpenAI faces internal and external scrutiny over controversies around its "Adult Mode" and overpromising about AI medical effectiveness.
This case not only challenges Perplexity's privacy protection mechanisms but also reveals deep contradictions in generative AI search engines regarding data monetization and user privacy boundaries. As compliance increasingly becomes a core competitive advantage for AI products, the outcome of this lawsuit may prompt the industry to re-examine the standards for using third-party tracking technologies in AI interaction environments.
