The 31-page complaint contends that xAI ignores users’ “reasonable expectations of privacy” by disclosing complete Grok conversation details, including discussions about finances, health, legal matters and other private topics, to major technology companies known for their extensive data collection and targeted advertising practices.

Grok, touted as “your truth-seeking AI companion for unfiltered answers,” is a large language model (LLM) that allows users to engage in conversational exchanges similar to other AI chatbots, the case relays. However, Grok.com is designed such that every query and resulting conversation, including every question asked by users and answered by the LLM, is assigned a unique URL, the filing states.

“The privacy implication of this is any party that Grok shares the URL with is able to obtain a full transcript of the conversation,” the Grok lawsuit summarizes.

According to the complaint, web tracking tools from Google, Meta and TikTok ascertain users’ information directly from xAI and use it to support advertising and user data-tracking systems.

The lawsuit references a recent report titled “Your AI Assistant Is Leaking Your Conversations,” which found that when users engage with Grok, xAI enables Google to access conversation URLs and related page metadata. Crucially, the report alleges that this disclosure to Google occurs regardless of cookie preferences.

Per the suit, Google uses data gathered through its analytics and advertising systems to strengthen user profiles and improve its ad-targeting capabilities.

The complaint similarly contends that Meta accesses Grok user data through embedded site tools such as the Facebook Pixel, which tracks visitor activity and connects that information to Facebook user accounts. According to the case, xAI incorporated Meta’s tracking technology into the platform to profit substantially from targeted advertising tied to users’ personal information.

The lawsuit further claims that TikTok uses a comparable tracking tool known as the TikTok Pixel, which enables the company to “eavesdrop on, record, extract information from, and analyze a conversation” on platforms utilizing the tool, including X.

The suit accuses xAI of violating the federal Electronic Communications Privacy Act, which prohibits the intentional interception of electronic communications, and the California Invasion of Privacy Act, which protects Californians from unauthorized online eavesdropping.

The Grok class action lawsuit seeks to represent all individuals whose personally identifiable information and communications with Grok were disclosed to third parties as a result of using the site.
