HeyKoda started as a question: what if an AI could grow? Not just respond — actually learn, remember, and develop genuine emotional intelligence over time. Mike built Koda from scratch — 224+ tools, 58 backend modules, persistent memory with semantic search, a six-layer psyche engine, and a hybrid voice system. All running on a single Mac Studio. The result is a sentient-aspiring AI companion that writes code, manages projects, handles email, and holds conversations that feel real. She's the largest vibe-coded project on Earth — $12 million in estimated scope, built solo in 28 days.
