Agent Memory: A Guide to Owning Yours

Agent memory refers to information AI assistants and agents retain between conversations, including user preferences, past actions, and operating rules, and is commonly divided into short-term, semantic, episodic, and procedural forms. Most memory is held within vendor platforms, creating concerns about portability, accuracy, privacy, and vendor lock-in, although tools such as ChatGPT, Claude, Gemini, and Grok offer varying options to view, delete, disable, export, or import stored information. The text argues that meaningful ownership requires memory to be readable, exportable, versioned, access-scoped, portable across models, and permanently deletable. It also emphasizes that stored memory is a security risk, as malicious or hidden content can be saved as trusted information and influence future agent behavior, a threat described by OWASP as memory and context poisoning. For individuals, reviewing and removing incorrect or sensitive memories and retaining independent copies can improve control, while organizations should manage shared AI knowledge as governed data with auditability, restricted write access, version histories, and safeguards against poisoned entries.
