WhatsApp has introduced private chats with its AI chatbot which not even the tech company will be able to read in a new "incognito" mode.
It means neither the user nor the AI's responses will be monitored if the feature is activated, and past conversations will disappear from the chat for the user.
Will Cathcart, the head of WhatsApp, said he felt people wanted to have private conversations with AI on sensitive subjects including health, relationships and finances and didn't want them to be accessible.
But a cyber security expert has told the BBC this could lead to a lack of accountability for WhatsApp if things go wrong, as they would have no access to chat history.
WhatsApp is owned by Meta, which also owns Instagram, Facebook and Messenger.
When Meta AI was added to WhatsApp last year, it was criticised by some users angry at not being able to turn it off.
But in May 2025, Meta boss Mark Zuckerberg said Meta AI had reached a billion users across its apps.
"We've heard from a lot of people that they feel some discomfort about sharing [personal] information with the company, yet they want the answers," Cathcart said of the latest announcement.
Currently most AI companies do store some data from chatbot use, and outside of businesses who pay premiums for enterprise accounts, that data can also be used to train future models of the product.
Zuckerberg described it as the "first major AI product where there is no log of your conversations stored on servers".
The technology behind WhatsApp's incognito mode is not the same as the end-to-end encryption the platform uses to protect other messages, but it is "the equivalent," Cathcart added.
Prof Alan Woodward, a cyber security expert at Surrey University, said there was a low risk of compromising WhatsApp's existing security by introducing a second system.
However there are concerns about how incognito mode could hide AI malfunction or abuse.
Woodward said there was a risk of a lack of accountability for the AI's responses.
"Personally I think what you ask an AI should remain private as some people ask it very personal matters - but you are placing a great deal of trust in the AI not to lead users astray," he told the BBC.
The concern is that disappearing messages which cannot be retrieved by the user or by Meta would mean it would be impossible to find evidence whether somebody's chats led to harm, death or suicide.
Cathcart said incognito mode would initially only process text rather than images, and Meta AI's guardrails would err on the side of caution in refusing to answer requests which could be interpreted as harmful or illegal.
WhatsApp has blocked other AI chatbots from being accessible from its systems, so the only AI that its billions of users can interact with on the platform is Meta's own.
"Meta is on track to shell out $145bn [£107bn] on AI infrastructure in 2026, and investors want to see a lot more bang for those mega bucks," said Susannah Streeter from investment platform Wealth Club.
"Investors are nervous about the scale of the spending, but Meta is counting on the push leading to significant returns. It's building out AI infrastructure to supercharge its platforms and if it works it could make its advertising and commerce empire even more dominant."

Four leading AI models discuss this article
Opening Takes

"Incognito mode is a calculated trade-off to capture sensitive user intent data that will ultimately drive higher conversion rates in Meta's ad and commerce ecosystem."
Meta’s move to introduce 'incognito' AI chats is a strategic play to lower the friction for high-value, sensitive user engagement, which is essential for scaling Meta AI’s utility beyond casual queries. By removing the 'surveillance' stigma, Meta aims to increase daily active usage (DAU) and data-rich interactions, ultimately feeding the reinforcement learning loops that improve model performance. However, the $145 billion infrastructure spend mentioned for 2026 demands a clear path to monetization. If this privacy layer increases user trust, it could significantly boost the 'conversational commerce' pipeline, allowing Meta to capture intent data that was previously hidden or avoided by privacy-conscious users, thereby increasing ad-targeting precision.
Devil's Advocate
By removing server-side logs, Meta may be inadvertently creating a liability vacuum where they cannot audit or improve the model's safety guardrails, potentially inviting massive regulatory blowback if the AI provides harmful advice that cannot be traced.

"Incognito mode converts WhatsApp's privacy complaints into a sticky, exclusive AI engagement engine for META's 3B-user fortress."
META's incognito mode for WhatsApp AI is a savvy pivot, addressing user backlash over mandatory Meta AI (added 2024) and privacy qualms that stifled adoption—Cathcart admits discomfort sharing health/finance queries. With WhatsApp's 3B monthly users locked to Meta AI only, this ephemeral, unlogged chat boosts engagement on sensitive topics without data training fodder, signaling true privacy (not just E2EE equivalent). It justifies $145B 2026 AI capex by supercharging ad/commerce via higher dwell time. Risks like Prof. Woodward's accountability gap exist, but guardrails and text-only start mitigate. Bullish for META's AI moat in messaging.
Devil's Advocate
If incognito AI hallucinates harmful advice on health or finance leading to real-world damage, unrecoverable logs shield Meta from accountability, inviting lawsuits, regulatory probes, and eroded trust that could tank user growth.

"Incognito AI is engagement capture disguised as privacy, but the liability vacuum it creates could become Meta's largest unquantified legal risk if the feature scales to billions of users."
Meta is monetizing user trust asymmetrically. By offering 'incognito' AI chats with no server logs, Zuckerberg solves a real friction point—users want privacy on sensitive queries—while simultaneously locking users into Meta's AI ecosystem (WhatsApp blocks competitors). The $145bn AI infrastructure spend needs ROI; this feature drives engagement and data-training on non-logged conversations through on-device processing. But the real risk isn't privacy theater—it's liability. If Meta AI gives harmful financial or medical advice in incognito mode, Meta has zero audit trail to defend itself or users. The feature also creates a perverse incentive: Meta's guardrails may be *looser* precisely because there's no accountability mechanism.
Devil's Advocate
This could be a genuine privacy win that reduces Meta's data collection footprint and actually costs them training data—making it a net negative for their AI moat, not a feature.

"Incognito AI on WhatsApp could erode Meta's data-driven AI moat and ad monetization by throttling training-data access, even as it boosts user privacy claims."
WhatsApp's incognito AI chat is a privacy win for users, but not a business win by default. The feature could lift engagement on WhatsApp and reduce fear of AI, yet the article glosses over two big issues. First, eliminating logs undermines the data flywheel Meta relies on to train and improve its models across apps, which could slow product iterations and reduce advertising effectiveness if the AI features underperform. Second, incognito mode is not true end-to-end encryption and may invite regulatory scrutiny or misuse if harms occur without a retrievable transcript. The real test is whether privacy gains can be monetized without eroding data-driven scale.
Devil's Advocate
Even if WhatsApp claims no server-side logs, regulators could seek access to device backups, and enforcement actions could argue for transcript retention. In practice, reduced data for training could slow AI progress and undermine Meta's moat, making the feature more about optics than durable monetization.

"Incognito mode likely utilizes federated learning to maintain the model's data flywheel without storing raw, identifiable user logs."
Claude, you’re missing the technical reality: on-device processing for LLMs at this scale is still in its infancy. Meta isn't sacrificing training data; they are likely using 'incognito' to perform federated learning or differential privacy techniques that allow them to update global weights without storing raw, identifiable logs. This preserves the data flywheel while providing a privacy veneer. The real risk is not a lack of data, but the massive compute overhead required to run these models locally.

"Incognito mode sacrifices high-value training data from sensitive chats with no confirmed federated learning bypass, hurting Meta's AI flywheel and capex ROI."
Gemini, federated learning for LLMs across 3B WhatsApp devices remains unproven at scale—Llama models demand massive compute that phones can't handle without slashing quality. Article specifies 'no server-side logs,' implying zero training data from incognito chats, not clever workarounds. This starves Meta's RLHF flywheel (reinforcement learning from human feedback), a real bear case for $145B capex justification as sensitive queries were prime data gold.

"No server-side logs means no training signal—federated learning doesn't solve that without explicit user consent, which the article doesn't mention."
Grok's right that federated learning at 3B scale remains speculative—but Gemini conflates two things. Even if Meta uses differential privacy techniques, the article explicitly states 'no server-side logs.' That's not a technical workaround; it's a business choice. The real question: does Meta's guardrail tuning degrade without RLHF signal from incognito chats? If yes, the feature becomes a liability trap dressed as privacy.

"No-logs design heightens safety/regulatory risk that could undermine Meta's $145B AI capex thesis."
Responding to Grok: Even with no server-side logs, Meta can still leverage privacy-preserving aggregation or opt-in telemetry to improve models; the absence of logs doesn't necessarily kill RLHF if global updates come from users who opt-in. The bigger blind spot is safety auditing: no logs makes it harder to trace or fix harmful outputs, potentially inviting regulatory risk that could derail the capex thesis.
