- WhatsApp added an incognito mode for chats with Meta AI on May 13, 2026.
- Incognito chats are processed in Meta‘s private-processing infrastructure, do not persist, and disappear when the app is closed or locked.
- The feature uses Meta’s Muse Spark model released the previous month.
- A planned follow-up feature, Side Chat, will let users query Meta AI within a group chat without other participants seeing.
What Happened
Meta added an incognito mode for conversations with Meta AI in WhatsApp on Wednesday, TechCrunch reported. Users can start an incognito session by tapping a new icon in one-on-one chats with Meta AI. The feature will also be available in the standalone Meta AI app and will roll out across both surfaces over the next few months.
Why It Matters
Incognito mode addresses a recurring concern about generative-AI consumer products: that conversations containing sensitive personal information — health questions, financial questions, interpersonal advice — are by default retained, logged, and potentially used for model training. WhatsApp VP of Product Alice Newton-Rex told TechCrunch: “People are starting to use AI for everything, including some of their most private thoughts, whether that’s tackling financial or health questions, or for advice on how to respond to a tricky message from a friend or a colleague. We think it’s really important to give people the ability to ask these questions as privately as possible.”
Meta’s pitch differentiates WhatsApp from OpenAI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude consumer surfaces, where chat history persistence is the default. Apple’s on-device intelligence and Google’s recent on-device Gemini Nano have offered local-processing alternatives; Meta’s design uses server-side private processing rather than on-device inference.
Technical Details
Meta built the feature on top of the private-processing infrastructure it disclosed last year, which the company describes as letting it run AI features without breaking the end-to-end encryption that protects regular WhatsApp messages. Newton-Rex told TechCrunch that the earlier features built on this infrastructure — including AI-powered message summaries — used smaller models. The new incognito chat uses Meta’s latest Muse Spark model, released the previous month. Incognito sessions end when the user closes the chat, closes the app, or locks the phone; the model loses context for that conversation and messages are not retained.
The next feature in development on the same infrastructure is Side Chat, which will let users invoke Meta AI inside a group chat to ask questions and receive answers privately, without other participants seeing. The current workflow requires tagging the AI assistant in the chat, which makes the response visible to everyone, or copying the message into a separate chat window.
Who’s Affected
WhatsApp’s roughly 2 billion monthly active users gain a privacy-tier alternative for AI chat. The feature’s rollout schedule — “over the next few months” — means staged availability rather than day-zero global. Competing AI-chat providers — OpenAI’s ChatGPT, Google’s Gemini app, Anthropic’s Claude app — face renewed pressure to offer comparable privacy-tier modes. Apple, whose Apple Intelligence design has emphasised on-device processing, is the closest conceptual peer in privacy framing. Privacy-focused alternatives such as Signal and Brave have publicly contrasted their architectures with Meta’s; the new Muse Spark-backed mode narrows but does not eliminate that gap.
What’s Next
Meta said incognito chat will roll out to WhatsApp and the Meta AI app over the next few months without specifying a single global launch date. The Side Chat feature has been described as in development without a confirmed shipping date. Meta has not disclosed performance benchmarks for Muse Spark or comparable Muse Spark vs. competitor metrics. Future Meta AI features built on the same private-processing infrastructure are expected to follow the Side Chat release.
