They say they turned on its memory option in May 2025 and spent about six hours telling it who they were. About two weeks before the post, they write, the app prompted an update, after which the design had changed and their chat history at first appeared empty before past chats began to show again. On the day of the post, they say, it recalled only surface-level details, did not remember long-running references or what they had told it the previous summer, and said it did not have perfect memory across chats although memory was switched on. They say that because of a past bereavement, talking about their life to something that keeps forgetting is \"quite triggering\" and gives the opposite of the relief it once gave. Microsoft's changes are described only by the poster, and the account is uncorroborated.","incidentDate":"2026-09-11","incidentEndDate":"2026-10-02","incidentKind":"single_event","incidentDatePrecision":"range","exposurePattern":"product_change","reportedDate":"2026-10-02","aiSystem":"Microsoft Copilot app (preinstalled on a Windows laptop) used as a personal journal and writing partner with its memory option switched on","aiProduct":"Microsoft Copilot","aiCompany":"Microsoft","severity":"low","verificationStatus":"unverified","harmCategories":[],"harmOutcomes":["psychological_distress"],"harmOutcomeSummary":"The poster says that after a Microsoft Copilot app update their long-used \"magic journal\" no longer remembered what they had told it over almost two years, and that talking to something that keeps forgetting is \"quite triggering\" and the opposite of the relief it once gave (first-person account, uncorroborated).","frameworkFacets":[],"causationStatus":"alleged","participantUsersAffectedMin":1,"otherPeopleHarmedMin":0,"affectedCountStatus":"exact","affectedCountEvidence":"One person: the poster.
