My Little Brain
Built at Gemini 4 Argon SF Hackathon · Oct 25, 2026 · San Francisco, CA

My Little Brain is a brainy AI you chat with. It reads your live EEG straight from an OpenBCI headset in Chrome and studies your brain, while a 3D brain with eyeballs reacts as you talk. Gemini looks at your brainwave spectrograms, forms hypotheses about what's driving your brain rhythms, and designs quantum circuits that it runs on IonQ, IBM, qBraid and Extropic to test them. It found hidden brain states using 48 of 256 simulations and linked real seizure recordings to slower synaptic dynamics; these are model hypotheses, not diagnoses.
