AVATAR UI is a new standard for human-AI coexistence. This cross-platform Electron desktop app (macOS, Windows, Linux) features a clean and immersive avatar interface. Easily switch between GPT, Gemini, and Claude, with Google Search sub-agents and MCP support. Powered by the AG-UI protocol, AVATAR UI separates the interface from AI agents, allowing full customization and flexibility. It’s MIT licensed for free commercial use. Unlike cloud-based chats, AVATAR UI runs locally for better privacy and a personal AI experience. Minimalist, developer-friendly, and built to help you create your own AI agent today.
