IT Home reported on November 9 that, according to the latest code findings shared by code researcher pdfu, Apple is developing a personal memory system that could help Siri remember various details about users' lives.
According to the findings, in the iOS 27.3 beta, the system includes a component called “Memory Graph,” designed to organize users' relationships, frequently visited places, daily habits, health conditions, exercise, and factors that motivate them or hinder them from achieving their goals.
IT Home noted that the system also includes data units called “Memory Atoms,” designed to record facts, opinions, intentions, and events, and link them to specific information such as relevant people, places, times, and topics.
According to pdfu, the graph collects information through two processing mechanisms. One converts structured data into insights, such as by reading the name field in a user's personal contact card. The other uses on-device AI models or Apple's Private Cloud Compute to extract information from sources such as Siri conversations, messages, photos, and health data.
At present, only one of the AI-driven information-processing mechanisms appears to be present in the code. pdfu believes it is designed to identify users' motivations, obstacles they face, and resources available to them through a set of built-in questions. The system includes 60 questions, including one asking which daily habits might affect a user's ability to get enough sleep.
However, based on the code disclosed so far, the system remains unfinished. For example, pdfu pointed out that the code does not yet include a process for creating “Memory Atoms.”
In a subsequent explanation, pdfu also distinguished Memory Graph from another, separate explicit memory storage system. The latter reserves storage space for records in Apple's search system, but no program currently writes records to it.
Both systems reportedly use Apple's version of the Kuzu graph database. Apple acquired Kuzu in 2025, but when news of the acquisition emerged earlier this year, it was still unclear how Apple intended to use the technology.
In fact, Siri already has personal context awareness and can find information related to users' lives in apps such as Mail, Messages, and Photos. The newly disclosed code does not reveal when the unfinished memory system will officially launch or explain how Apple will allow users to manage and control their data.
