Apple is building a personal memory system for Siri that could help the assistant retain information about users' lives. The system, found in iOS 27.3 beta, includes a "memory graph" designed to organize information about relationships, places, routines, health, workouts, and user motivations or barriers. The system also identifies "memory atoms" for facts, opinions, intentions, and events involving people, places, times, and topics.
According to code explorer pdfu, the graph uses two processes to gather information: one turns structured data into insights, such as reading a user's contact card, while the other uses an on-device AI model or Private Cloud Compute to query Siri conversations, messages, photos, and health data. Currently, only one AI-driven process is present, designed to identify motivations, barriers, and resources using 60 built-in questions. The system remains unfinished, as pdfu notes there is no process yet that creates memory atoms.
Both systems reportedly use Apple's version of the Kuzu graph database. Apple acquired Kuzu earlier this year, though its plans for the technology were previously unclear. This follows Apple's existing personal context understanding in Siri, which allows the assistant to find information in apps like Mail, Messages, and Photos.
No timeline has been revealed for when the unfinished system will become available or how users will control their data.
