Backyard AI

Backyard AI provides a local environment for creating and interacting with AI‑driven characters through text and voice. Users can define personalities, backstories, and dialogue styles, then engage in immersive chats without external filtering. The platform supports dynamic audio output, allowing characters to speak with customizable voices.

The system includes tools such as Lorebooks for supplying contextual world information, an Author’s Note for setting scene or tone, and Grammars to enforce specific response formats or narrative structures. Advanced model parameters let users adjust token sampling, context length, and prompt templates for fine‑grained control over behavior.

Targeted at creators and hobbyists who want to run AI models on macOS, Backyard AI offers a stable, locally hosted solution that emphasizes customization and interactive storytelling without requiring cloud services.
