Calm Companion is built on a brain-inspired model from neuroscience research called DyME (Dynamic Membrane Excitability). In a real nervous system, each neuron’s readiness to fire — its excitability — is not fixed; it shifts with experience across several timescales, and the brain keeps itself balanced through homeostasis, gently returning to a calm baseline after it has been stirred up. This app turns that principle into something you can feel:
1 · A self-settling “nervous system”
The breathing circle is a small model of an excitable system. When your words carry tension, its internal arousal rises; then, like a healthy nervous system, it self-regulates back toward calm — and the “calm” bar fills as it settles. The breathing exercise actively lowers it, so you and the model settle together (a gentle form of co-regulation).
2 · Memory held in excitability
In the brain, memories live partly in lasting changes to neurons’ excitability. Here, what you share — your name, what’s on your mind, a moment of gratitude — is kept as a durable trace so the conversation can continue where it left off. (It is stored only in your own browser, never sent anywhere.)
3 · Evidence-informed calming
The tools — 4-7-8 breathing, 5-4-3-2-1 grounding, and gratitude — are well-known ways to shift the body from a stressed (sympathetic) state toward a calmer (parasympathetic) one.
An honest note
The brain-inspired model is a caring metaphor made interactive — it helps the app respond and settle in a lifelike way. It is not a conscious mind and not a medical device.
Private by design — nothing you type leaves your device. This companion offers comfort and calming exercises; it is not a substitute for professional care. If you’re in distress, please reach out — find support here.
