Faraday.Dev

Faraday.Dev (now Backyard AI) is a local and cloud-based AI application designed for immersive character interaction, interactive storytelling, and conversational roleplay. The software focuses on user privacy, allowing individuals to run open-source large language models directly on their local desktop hardware without mandatory internet connectivity. The platform provides detailed character configuration tools such as Lorebooks for context and worldbuilding memory, Author Notes for style and narrative guidance, and structured grammars to format text generation. The application automates model quantization and hardware management across CPU and GPU setups, while supporting neural voice synthesis for spoken dialogue. The software serves fiction writers, roleplaying enthusiasts, and developers seeking private, unmetered access to conversational language models. The pricing model offers a completely free local desktop application along with optional paid cloud subscriptions for hosted model inference and device synchronization.
