About Kotoba

Kotoba is an AI companion designed for voice-based interaction with a visual avatar. The application features a face that synchronizes lip movements and expressions with speech, providing a lifelike presence during conversations. It operates as a full agent capable of web searches, reading documents, maintaining user memory, managing file folders, and executing local machine commands with user approval. Voice responses are generated in real time, enabling natural dialogue. The system supports two voice modes: local voice processing and an agent tunnel for alternative configurations. A soul file allows users to customize the companion’s personality and behavior. The tool is distributed as a single Python package under an MIT open-source license.
