Lucid uses clinically validated voice biomarkers right on your desktop to detect when stress is compromising your judgment — before your board does. No wearable required.

This isn't a wellness app. It's a founder operating system.
When you're under chronic stress, your autonomic nervous system alters how your vocal cords vibrate. Micro-changes in pitch, jitter, shimmer, and spectral energy — signals you can't control, can't fake, and can't suppress. You've trained yourself to perform under pressure. Your voice hasn't. It leaks what you hide.
A 244M-parameter model trained on 35,000 patients reads these signals from 25 seconds of natural speech. In clinical studies, AI detected stress markers 6.7 minutes before self-report. Founders average 37 meetings per week and 72% of their work time is verbal — the highest voice data volume of any profession.
Lucid turns every call, every pitch, every board meeting into a data point about your actual mental state. Voice biomarkers are involuntary neurological signals that bypass the cognitive filters you've spent years building. The signal is always there. Now something is finally reading it.
Not a questionnaire. Not a journal entry. A single score derived from involuntary vocal biomarkers — updated every call, every pitch, every standup.
Updated with every conversation. Your team never sees it.
Six acoustic signals. Every call, pitch, and board meeting, decoded into biomarkers no executive coach measures.
No calendar blocking. No daily check-ins. No one on your team needs to know.
The same AI validated on 14,898 patients. Running locally on your Mac's neural engine. Zero cloud dependency. Zero data exposure.
During calls, standups, investor pitches — Lucid passively extracts 20+ acoustic features and analyzes them in real time. You don't change a thing.
Within days, you'll have continuous data on stress, cognitive load, emotional resilience — the kind of self-knowledge that used to require a breakdown to discover.
Executive coaches charge $500-1,000/hour. Therapists charge $200-400/session — if you could even find the time. Lucid gives you continuous decision-readiness monitoring for less than a single copay. The research was funded. The model was validated. Apple Silicon made it runnable.

The world's highest-performing organizations don't guess about mental state. They measure it.
Track player mood and mental readiness weekly as part of standard athlete monitoring systems.
Reduced injury rates by 22% after integrating mental readiness monitoring into their performance program.
Five-time NFL All-Pro DeAndre Hopkins and Olympic athlete Colleen Quigley back voice-based AI performance tracking through Sonde Health's advisory board.
The Premier League uses these insights to prevent injuries. Elite athletes use them to sustain peak performance. Lucid brings the same approach to the founder who can't afford an off day.
No. Lucid runs 100% on your machine. Your voice is processed locally and never uploaded. Only numerical biomarker scores are stored — on your device. There is no cloud component. No one sees your data but you.
Lucid requires zero time. It runs passively during calls you're already on. There's nothing to open, nothing to fill out, nothing to remember. If you spend time in meetings, Lucid is already working.
The underlying model was validated on 14,898 patients in a double-blind study published in Annals of Family Medicine. 71.3% sensitivity for depression detection — comparable to standard clinical screening — but measured continuously instead of once a year. And founders generate more voice data than almost any profession: 37 meetings/week, 72% of work time verbal.
No. Lucid is a monitoring tool, not a treatment provider. Think of it as a continuous check-engine light for your mental state. It complements coaching by giving you objective data — or it serves as an early warning system for founders who don't have time for regular sessions.
That's exactly the point. 73% of founders experience shadow burnout — burned out while still performing. The danger isn't in knowing. It's in not knowing until your judgment fails on the decision that matters most.
Not yet, but team plans are coming. Imagine knowing — objectively, not anecdotally — which meetings drain your team, which weeks are unsustainable, and when someone is struggling before they tell you. That's the roadmap.
Lucid is a wellness tool, not a medical device. The underlying Kintsugi DAM is clinically validated and peer-reviewed, but Lucid provides voice biomarker data for personal wellness — similar to how Oura provides HRV data without being a medical device.
Nowhere. Literally. The model runs 100% on your machine. Your voice is processed locally and never uploaded to any server. Only numerical biomarker scores are stored, on your machine. Lucid works with your internet disconnected — that's how you know.
You can't show vulnerability to your team. You can't show it to your investors. You can't show it to your board. You can show it to Lucid.
The technology exists. It was built for clinical research. Now it runs on your Mac.
