Memory and companionship glossary
Persistent memory is information a service keeps beyond the immediate conversation and can use in a later session. For an AI companion, that might be a saved preference or a short relationship summary. It does not necessarily mean the character remembers every message, and stored information is not always used in every reply.
Definition
Persistent memory in an AI conversation system means retaining selected information across sessions and making it available for later responses. It can be implemented with saved facts, summaries or other stored records that the application retrieves when relevant. It is distinct from the current context window, the complete chat transcript and the model’s training. Saving a detail and correctly recalling it are separate steps.
By the Prelulu editorial team · Updated
An implementation example of application-managed storage that can be read across sessions outside the current context window. This is not a claim that every companion app works the same way.
You tell a character that you prefer quiet walks to crowded parties. If the service saves that preference and retrieves it in a later conversation, the character may suggest a walk. The preference can persist even though the entire earlier chat is not sent again.
A saved detail can be mistaken, outdated or no longer welcome. Look for a way to inspect, correct or remove stored information and read what the service says about deletion. A friendly response promising to forget is not, on its own, a technical deletion receipt.
Remembered preferences can make a conversation feel more continuous, but they do not establish human understanding, sentience or an emotional commitment. In Prelulu, saved relationship details and recent conversation context can inform calls; complete recall of every past line is not guaranteed.
FAQ
Not across every service. Chat history and saved-memory stores can have separate controls and retention behavior. Check the application’s actual data controls rather than assuming one delete action covers both.
Yes. A stored detail might not be retrieved for a particular response, might be summarized differently or might have been changed. Persistent storage does not guarantee correct use on every turn.
No. A short scene can work within its current context. Persistent memory becomes useful when you want selected details or a relationship premise to carry into later sessions.
Choose a character for conversation, roleplay or a live call. Check the current plans and available credits before calling.
