Chronic stress is wrecking tech workers and nobody's measuring it. Lucid is a desktop app that monitors your stress through your voice, tracks your baseline over time, and shows you what's actually working to lower it. No wearable. Just your laptop mic.

Continuous stress monitoring through your voice. No questionnaires. No wearable. Just your laptop mic.
You track your steps, your sleep, your heart rate. But not the thing that's actually destroying you.
You know you're stressed. That's not the problem. The problem is you can't see it changing over time. You don't know if it's getting worse. You don't know which days are bad and which are fine. You don't have a baseline. So you can't tell if anything you're doing is actually helping.
Research shows AI can detect stress markers from voice patterns 6.7 minutes before you'd notice them yourself, with 84.7% accuracy. Your voice changes when you're stressed. Micro-shifts in pitch, jitter, and spectral energy that you can't control or fake. That's what Lucid measures. Continuously. Passively. Every time you talk on your laptop.
Unmanaged workplace stress doesn't just feel bad. It compounds. Population-level data shows anxiety and depression are associated with dying 7.9 years earlier. You can't improve what you can't measure. And right now, the biggest threat to your mental health at work isn't measured at all.
That's why we built Lucid. A desktop app that measures your stress so you can actually lower it.
Lucid tracks your stress continuously through your voice. You'll see daily and weekly trends, know your personal baseline, and spot when things are getting worse before you burn out.
A real-time timeline of your vocal stress throughout the day. See when you peaked, when you recovered, and how your stress shifts hour by hour. All processed locally on your laptop.
Lucid matches your vocal stress data against your calendar. It won't tell you why a meeting is stressful. But it will show you which ones correlate with your highest stress readings.
Don't just take our word for it.
Here's what changes when you stop guessing.
Takes about five minutes to set up. Here's how.
Download the Mac app. Open your laptop. That's basically it.
The same clinical model validated on 14,898 patients, running locally on your Mac. No cloud. No wearable to charge. Just a desktop app.
During normal calls and conversations, the app passively picks up 20+ acoustic features from your voice through your laptop mic. No questionnaires. No manual logging. It just runs in the background.
Within days, you'll have a stress baseline, daily trends, and weekly patterns. You'll see what's working and what isn't. Make changes, then watch the data to see if they helped.
The question isn't whether it works. It's whether you'll use it.
"Week 1, I could see my stress baseline for the first time. Week 2, I started making small changes. Week 3, my stress score dropped 31%. I didn't work less. I just had data telling me what was actually working."

Function Health took a $10,000 lab panel and made it $1/day. Lucid takes the voice monitoring system used by 80% of Premier League clubs and runs it on your Mac for $14.99/month. No $300 wearable. No hardware at all. The research was funded, the model was validated, and Apple Silicon made it runnable on your laptop.

Yep. The same mic you're already using for Zoom calls. The clinical model behind Lucid was validated on 14,898 patients using standard microphones, not medical-grade equipment. Your MacBook mic is more than enough. No wearable, no special hardware, no $300 ring on your finger. Just the laptop you already own.
Nope. Everything runs locally on your Mac. Your voice is processed on your machine and never uploaded anywhere. Your company can't see it, we can't see it, nobody can see it. It's a personal desktop app. Your data stays on your laptop.
All of them. Zoom, Teams, Google Meet, Slack huddles, FaceTime. If you're talking on your Mac, Lucid picks it up. No plugins, no integrations, nothing to install inside those apps. It just listens through your mic while you do your thing.
Not at all. Most people who sign up already feel burned out. The problem isn't that you don't know you're stressed. It's that you can't see your stress changing over time and you don't know if anything you're doing is helping. Lucid gives you that data so you can make targeted changes and actually track whether they're working.
No, and it's not trying to. Lucid is a monitoring tool, not treatment. Think of it like a continuous stress monitor that gives you objective data. A lot of users share their weekly trends with their therapist, and it makes those sessions way more productive. You show up with data instead of trying to remember how you felt on Tuesday.
You don't need to be on calls all day. Lucid works with any voice activity, even short responses or a quick Slack huddle. The more you talk, the more data you get. But even a few calls a day is enough to build a stress baseline and track trends over time.
You don't need another wellness app or a $300 wearable. You need continuous stress data you can actually act on. Lucid gives you that from the mic you're already talking into.
