Apple will launch iOS 27 at WWDC on June 8, with a revamped Siri chatbot at its core. Bloomberg’s Mark Gurman revealed that the new Siri will introduce an "auto-delete conversation" feature and adopt differential privacy technology to decouple AI memory from user identity. (Previous coverage: OpenAI reportedly plans to sue Apple for "breach of contract," claiming Siri's integration of ChatGPT fell short and caused a loss of billions in subscription revenue) (Background: Headphones with eyes? Apple AirPods with built-in cameras reportedly enter final pre-production testing) ChatGPT, Gemini, and Claude are all competing to "remember more about you," but Apple has chosen to bet on a different direction: making Siri forget what you said faster than any competitor. This is the privacy card Apple is preparing to play at WWDC on June 8. The current mainstream competitive logic for AI assistants is "memory equals stickiness." ChatGPT’s Memory feature remembers user preferences, habits, and background; Gemini can connect to Google accounts to read personal context from Gmail and Calendar; Meta AI builds personalized models based on behavior data from Instagram and WhatsApp... The core premise of this logic is: the more the AI knows about you, the more you will rely on it. But Apple’s choice for WWDC 2026 is not to follow this logic. According to a report by Bloomberg technology editor Mark Gurman, the new Siri in iOS 27 will support an "auto-delete conversation" feature: users can choose to store conversation history permanently, set it to auto-clear after 1 year, or set it to be completely wiped after 30 days. The settings interface is similar to the auto-delete feature for messages in iMessage. This is different from the existing "Incognito Mode." ChatGPT’s temporary chat mode means "not saving after this conversation ends," but the AI’s existing memory bank remains unaffected. Apple’s auto-delete means the conversation itself disappears completely after the time expires: it deletes the past, not just the present. Auto-delete is one of the options, but its existence maintains Apple’s consistent stance. Beyond auto-delete, Apple has also introduced another layer of privacy protection: differential privacy. Differential privacy is a statistical protection technique. In plain terms: the AI can remember what you said, but mathematical noise is added to this memory during storage, making it impossible to trace it back to you as a specific individual. The memory is stored locally on the device rather than synced to cloud servers: this means that even in the event of a data breach, attackers would find it difficult to reconstruct the conversation content of specific users. From a user experience perspective, differential privacy means Siri’s memory is like a "slightly blurry scribe"—it knows what kind of questions you tend to ask, but it may not precisely remember every single sentence. The memory exists, but there is a mathematical distance between it and your identity. Google and Apple have long used differential privacy for features like keyboard auto-complete and speech recognition; the technology itself is not new. Apple’s new move is to formally introduce it into the memory management of an AI chatbot and clearly explain this in its marketing language. The cost is real. Gurman pointed out that Apple’s design makes the new Siri practical enough for short-term use, but the accumulation speed of long-term memory is not as fast as competitors like ChatGPT. In other words, your Siri may never truly "know you," but what Apple wants to do is redefine this from a flaw into a selling point. Apple has used privacy as a differentiator for over a decade. From iMessage end-to-end encryption to App Tracking Transparency—which caused Meta’s advertising revenue to evaporate by over ten billion dollars a year after its launch—to comparing itself with Google and Meta at every product launch: Apple has consistently used "we don't treat your data the way they do" as its core brand language. However, this time, Apple has to convince a group of users who have already been re-educated by ChatGPT and Gemini. For years, the market has anchored Siri as a "functionally limited voice assistant." The integration progress of Apple Intelligence in iOS 18 fell behind expectations, and the partnership agreement with OpenAI has also fallen into controversy. Against this backdrop, iOS 27 is set to relaunch with a new Siri that has "shorter memory but more privacy," aiming to complete a brand reconstruction at WWDC on June 8. But in the white-hot AI assistant competition of 2026, whether it will work remains to be seen after June 8.
