Synaptica

Synaptica is a mesmerizing neural network art engine where you create, connect, and bring neurons to life with a single tap. Place glowing neurons anywhere on your canvas, then fire them and watch signals cascade through your growing network. Connections strengthen through use — neurons that fire together, wire together — bringing real Hebbian learning to your fingertips. Draw sweeping patterns of neurons with your finger, reposition them with drag gestures, and watch your creation pulse with energy. Enable auto-pulse to let your network play itself like a living instrument. FEATURES • Create neurons with a tap, draw patterns by dragging • Fire neurons and watch chain reactions propagate • Real Hebbian learning — connections strengthen through repeated firing • Soft-body physics with tilt-based gravity • Pinch to zoom and pan to explore your creation FOUR VISUAL THEMES • Cosmic — ethereal purple and cyan with glass bell sounds • Synapse — organic greens with woody marimba tones • Circuit — electric blues with sharp digital clicks • Inferno — fiery oranges with deep drum thuds PROGRESSION • 26 challenges across Basics, Chain Reactions, Architecture, and Mastery • XP system with levels and achievement titles • Unlock new themes and expand your neuron capacity Each theme features its own procedurally generated audio — every firing neuron plays a unique note based on its position, creating an ever-evolving soundscape. Your networks auto-save and restore between sessions. Capture and share your neural artwork as screenshots. 100% offline. No ads. No tracking. No accounts. Just pure creative play.
