Perplexity AI Sued for Secretly Funneling Your Chats to Google and Meta
April 10, 2026 · 2 min read
A 140-page class-action lawsuit alleges the AI search engine embedded ad trackers that sent your prompts, responses, and personal data straight to Big Tech — even in incognito mode.
The Big Picture
A class-action lawsuit filed in San Francisco federal court accuses Perplexity AI of secretly sharing complete user chat transcripts with Google and Meta through embedded advertising trackers — turning a tool people trusted for private research into a data pipeline for the world's largest ad platforms.
Why It Matters
If you've ever asked Perplexity about your health, finances, legal situation, or anything personal — that conversation may have been shipped directly to Google and Meta before Perplexity even processed it. The lawsuit alleges this happened even when users enabled incognito mode, shattering the basic expectation of privacy that drew millions to the platform.
This isn't a minor data hygiene issue. It strikes at the core trust contract between AI tools and their users: that your prompts stay between you and the AI.
What's Happening
The 140-page complaint, filed by an anonymous plaintiff (John Doe), lays out a detailed technical case:
- The trackers: Perplexity allegedly embedded Meta Pixel, Google Ads, Google DoubleClick, and Meta's Conversions API directly in its codebase
- What was shared: Complete chat transcripts, prompts, AI responses, email addresses, IP addresses, and device fingerprints
- The timing: Data allegedly flowed to Google and Meta before Perplexity even displayed results to the user
- Incognito failure: The tracking reportedly persisted even when users activated Perplexity's privacy mode
- The class: All non-paying Perplexity users from December 7, 2022 through February 4, 2026 — potentially millions of people
- Potential damages: $5,000 per violation under federal wiretapping statutes
The Bottom Line
This lawsuit could reshape how AI companies handle user data. If the allegations hold, Perplexity wasn't just failing to protect privacy — it was actively monetizing the illusion of it. For anyone using AI tools for sensitive queries, the message is clear: read the fine print, check for trackers, and consider tools built with privacy as a core feature — not an afterthought.
The case to watch: Doe v. Perplexity AI, Inc. et al., U.S. District Court, Northern District of California.
