Lore AI gives game characters persistent memory, so they remember you, what you said, and what you did, and the world carries the consequences forward. Built by Robin Moulder and Patrick O'Shaughnessey on Meta's models and Unity. We want a game world that feels alive. Character dialogue, natural movement, dynamic environments, interactive objects and gameplay all work together, so the world responds instead of following a script. Characters remember what happened. Objects and environments carry the consequences. We combine Meta AI with the Unity Behavior graph to turn structured game events into believable, character-specific reactions, while the game reflects those events in its environment and gameplay. It is the foundation for a living world that remembers what the player has done, and responds. Every player's story is their own. The pinned objective is the same for everyone: get Flynn off the roof. Talk him down and he offers the ladder. Burn his house first and he reacts to the fire. No two players solve it the same way. Under the hood, Unity Behavior drives the characters and a Node service with PostgreSQL stores memory per player and campaign. The model proposes and the game authorizes: relationship changes must quote the player's exact words and follow authored rules, and Unity validates every action before it runs. A new character is a profile, relationship rules, and an action list. It is a standalone service, ready to deploy, and works for any AI character in any game or application.
