SHORT ANSWER
AI-pet “memory” can mean a saved preference, a recent event log, a model-generated summary, or a retrieved conversation. These are different data structures with different risks. Useful memory is selective, correctable, transparent, and easy to delete.
Profiles versus episodes
Stable facts such as a preferred name belong in a profile. Events such as a game played yesterday belong in an episodic record. Mixing the two makes errors harder to find and correct.
Retrieval, not total recall
Most systems cannot place an entire history into every response. They search or score stored items and provide a small relevant subset. Poor retrieval can make a real memory look forgotten or an irrelevant memory seem intrusive.
Summaries can drift
Generated summaries compress information but can introduce assumptions. Important facts should retain provenance and users should be able to view, correct, or remove them.
Forgetting is a feature
Retention limits reduce privacy risk and keep a character from becoming dominated by stale context. Products should explain what survives device changes, account deletion, and service shutdown.
