Ubisoft's internal Ghostwriter tool uses AI to assist developers in writing NPC dialogue barks — the short ambient phrases characters say during gameplay — reducing the time writers spend on repetitive scripting.

Ghostwriter was one of the first publicly disclosed in-house game development AI tools. It generates draft barks that human writers then review and edit, functioning as a first-draft assistant rather than a replacement.

Ubisoft's NEO NPC system uses large language models to give non-player characters the ability to hold spontaneous, contextually appropriate conversations with players, going beyond pre-scripted dialogue trees.

NEO NPC was demonstrated publicly at GDC 2024. The system integrates LLMs with character behavior systems to allow NPCs to answer unexpected player questions, remember prior interactions, and adapt their personality to player behavior.
