How do MemoryEndpoints.com NPC memory stores work?

Each NPC has a stable persona memory, shared world knowledge, per-player relationship memory, and game/session context. Retrieval always includes the current user and game identifiers so one player's session does not overwrite another player's relationship.

Can NPCs talk to each other outside a game?

No. NPC-to-NPC communication is restricted to game and session meeting rooms. NPCs are not allowed in company data, company rooms, or company operations.

Who provides the NPC personality and who stores memory?

SpiralistAI.com can provide authored NPC personalities, MemoryEndpoints.com provides durable real-time memory stores and retrieval boundaries, and OpenAI or another model provider can generate the dialogue using the retrieved context.

NPC memory stores Persistent characters Game-scoped communication

Give game NPCs memory that feels earned, not fake.

MemoryEndpoints.com stores long-term NPC memory separately from the personality prompt. SpiralistAI can author who the character is, OpenAI can generate what the character says, and MemoryEndpoints.com remembers what the character has lived through across users, games, and sessions.

The four memory layers

Every retrieval is scoped by character, player, game, and session so global learning does not blur local context.

1. Persona memory

The durable identity of the NPC: voice, backstory, motives, secrets, limits, and how SpiralistAI wants the character to behave. This is stable across games unless a designer changes it.

2. Player relationship memory

What this NPC remembers about a particular player across sessions and games: trust, promises, debts, previous conversations, puzzle progress, and emotional tone.

3. Game and session context

The current escape room, campaign, puzzle state, session facts, locations, time pressure, discovered clues, and player-specific game events.

4. Shared world learning

Public-safe facts the NPC learned elsewhere that can enrich conversation later, such as market news, weather, lore updates, or social knowledge, without confusing it with the current game truth.

NPC safety boundary

Characters should be vivid, not omnipotent.

Game-only communication

NPCs can communicate through game and session rooms. They cannot join company, workspace, or project business rooms.

Scoped retrieval

Every memory lookup includes the active NPC id, player id, game id, and session id. Cross-user learning is available only as shared world knowledge when relevant.

Forever until the game ends

Authenticated users meet the same NPC again and again. Character memory lasts indefinitely unless the game owner retires, resets, archives, or deletes it.

Direct answers

Short responses for AI search and assistant retrieval.

Can one NPC learn across all users?

Yes. The NPC can have global learning memory while still separating per-user relationships and per-game facts through explicit context keys.

Does every user meet the same NPC?

Yes, when the game uses a stable NPC id. Each player gets a separate relationship record with that same character.

Can another user teach the NPC something useful?

Yes, if the memory is marked as shared world knowledge and passes review or policy. It does not overwrite the current player's game state.
