Life by Synheart

Life is a life companion powered by Synheart's Human State Interface (HSI). It reads your behavioral biosignal and contextual data — how you type, your heart rhythm and what's going on from a wearable, your pauses, your rhythm — and gives you back a clearer sense of your own state. Focus. Stress. Recovery. Mental load. The things you usually feel but can't quite name. No content. No labels. No verdicts. Just your own patterns, in plain language. WHAT HSI ACTUALLY IS The Human State Interface is a new way for your devices to understand you — not through what you say or write, but through the signals your body and behavior naturally produce. Typing rhythm. Heart rate variability. Pauses. Bursts. Effort. Life turns those signals into a few honest indicators you can actually use through the day. YOUR DAILY READ • Readiness: how prepared your mind seems for focused work today • Regulation: Regulated, Mixed, or Dysregulated, based on how steady your focus has been • Mental Load: how demanding your day actually looked • Restorative: how rested your body is, the reserve your mind leans on • Focus Stability, Attention Continuity, Typing Effort, Engagement Capacity • Rhythm, Burstiness, Stress, Recovery, Strain — live, in the moment SYNI, YOUR PRIVATE COMPANION Syni is the conversational side of Life. Stressed, overwhelmed, or just curious about why today feels off — Syni reads your recent HSI signals and talks with you about what they suggest. It runs on-device. Conversations stay on your device. BEHAVIORAL + BIOSIGNAL, TOGETHER • Behavioral: the Synheart Keyboard captures the shape of your typing — never the words • Biosignal: pair a wearable to add heart-rhythm context like HRV and recovery • Either works alone. Together, the read gets richer. PRIVACY IS THE FOUNDATION, NOT A FEATURE • No text, passwords, or content ever captured • All processing on-device by default • Wearables are optional • Export or delete your data anytime • No emotion labels stored, no diagnoses SYNHEART PLUS Cloud Syni, full history, and the web dashboard — your companion, on any device. • Unlimited data history (Free is 30 days) • Encrypted cloud backup • Multi-device sync • Long-term trends across weeks and months A NOTE ON WHAT LIFE IS NOT Life is not a medical device. It does not diagnose. It does not score you as a person. It describes patterns in your behavior and biosignals — that's it. A "Mixed" reading is information, not a problem to fix. Trends matter more than any single window. Human signal intelligence, built privacy-first. A product of Synheart.
