Description

Keto is a multi-modal voice AI agent featuring three interactive arenas that showcase different AI capabilities. The Banter Arena provides natural conversations with web search integration for real-time information. The Puzzle Arena offers 10 brain-teasing challenges with progressive hints and conversational solving. The Paint Arena enables AI-powered image generation through voice commands. Keto solves the problem of rigid, single-purpose voice agents by creating an expressive, situationally-aware AI companion that adapts to different contexts - whether you need current information, mental stimulation, or creative assistance. With interruption handling, personality customization, and real-time web search, Keto demonstrates how voice agents can be both functionally powerful and naturally conversational.
