Bitpart

Bitpart AI is an AI NPC engine for game studios and game developers that adds world-aware characters with dialogue, behaviors, and multi-agent interactions to virtual worlds.

Key capabilities include:

• Pre-trained Archetypes: out-of-the-box NPCs with actions, animations, and dialogue, designed to be adapted or used as a starting point for custom characters.
• Coppola web authoring: a browser-based platform for creating interactive content such as dialogue and physical behaviors, aimed at enabling content creation at scale by non-technical teammates.
• Aesop multi-agent planner (AI Director): orchestrates dynamic conversations and coordinated behaviors for groups of NPCs (Casts), including interactions with players and each other.
• World-aware interactions: NPCs can interact with props, furniture, and other characters; the local AI SDK supports integration into games.

Pricing: Freemium. The Bitpart runtime is free with no royalties; Solo Developer plan $0; Pro plan $5,000 per title per year during development (teams of 10 or fewer); Enterprise via contact. Free trials available.

Notable for combining a local SDK, web-based authoring, and a multi-agent planning approach (based on Episodic Planning research) to support living worlds, dynamic cut scenes, and cinematic previsualization.
