Zenii is a versatile local AI backend designed to streamline access to AI tools across various interfaces. It operates a daemon at localhost:18981, allowing desktop applications, command-line interfaces (CLI), terminal user interfaces (TUI), and scripts to share the same memory, tools, and scheduling capabilities. This eliminates the need for synchronization or duplication of resources, making it ideal for developers seeking a cohesive AI environment. Users can easily install Zenii on macOS, Linux, or Windows, with the option to build from source if preferred.

The program features a robust architecture that supports multiple interfaces including a command-line tool, interactive TUI, and a desktop application. Key functionalities include persistent memory management, a knowledge ingestion system, multi-step reasoning capabilities, and a comprehensive tool registry. Zenii also supports various workflows and scheduling options, making it suitable for local automations and developer tooling that requires a shared AI backend.
