Mark Zuckerberg unveils a new fully private encrypted AI chat from Meta.

Meta’s CEO Mark Zuckerberg has introduced Incognito Chat, claiming it to be “the first major AI product where there is no log of your conversations stored on servers.” Unlike other AI chatbots that offer incognito modes, messages in Incognito Chat are not saved or stored in users’ chat histories. What sets Meta’s version apart is its use of end-to-end encryption, a feature recently removed from Instagram DMs. Zuckerberg emphasized, “Other apps have introduced incognito-style modes, but they can still see the questions coming in and the answers going out. Incognito Chat with Meta AI is truly private, meaning no one — not even Meta — can read your conversations.”

In contrast, Google retains data from temporary chats in Gemini for up to 72 hours. ChatGPT can store temporary chats for up to 30 days, while Claude keeps incognito chats for a minimum of 30 days. Anthropic and OpenAI have not yet responded to inquiries regarding this.

ChatGPT’s logs have become central to recent lawsuits related to mass shootings in Tumbler Ridge, Canada, and at Florida State University last year. Additionally, a lawsuit from a major news outlet has included a court order demanding the indefinite storage of conversations. Google is facing a similar lawsuit from the family of a 36-year-old man who allegedly received instructions from Gemini that led to a series of “missions” culminating in his death.

Meta’s Incognito Chat utilizes the same Private Processing technology that was launched last year for data processing in WhatsApp and is set to roll out “over the coming months” in both WhatsApp and the Meta AI app.
