How to Delete Specific Things an AI Remembers About You
Whether you can delete a specific AI memory depends on two things: which AI you are using and what storage format its memory uses. Consumer AI assistants like ChatGPT and Claude Projects let you delete individual memories through a settings panel — but only report success; they cannot prove the underlying data is gone. Developer-facing agent memory tools (Mem0, Letta, PLUR) offer deletion via API or CLI. The critical difference is the storage format: systems that store memory as plain files — open-format memory — can prove deletion with a file diff. Systems that store memory as vector embeddings or opaque database records cannot. This distinction matters for privacy-sensitive applications, GDPR compliance, and any scenario where a user needs to trust that deletion actually happened.
