Overview
Vtuber Assistant is an AI-powered co-host designed for virtual streamers and VTubers. It actively listens to stream content, responds to chat, and interacts with viewers in real time, making streams more engaging. The assistant can moderate comments, answer questions, and even participate in on-stream conversations naturally.
Available via Steam, Vtuber Assistant integrates with popular streaming platforms and VTuber software to provide an always-on AI companion. It uses conversational AI and context awareness to stay relevant during live broadcasts.
Agno (formerly Phidata) is a lightweight, ultra-fast Python framework engineered for building production-grade autonomous multi-agent systems with native memory, knowledge retrieval, and multimodal reasoning capabilities. It is designed to replace bloated agent frameworks with a pure, pythonic developer experience. Agno agents operate up to 10x faster than legacy orchestration libraries by eliminating unnecessary abstractions. With built-in support for vector databases (PgVector, Qdrant, Pinecone), structured output schemas, and agent-to-agent delegating protocols, developers can build complex autonomous assistants with under 20 lines of clean code.
The framework includes first-class multimodal tools allowing agents to analyze images, process video streams, execute code in secure sandboxes, and query SQL databases. Agno agents natively persist session state and user memory in PostgreSQL, making stateful conversations effortless across web sessions. Agno is fully open-source with extensive documentation, offering enterprise-ready middleware for authentication, telemetry, and rate limiting.
