Sleep from your watch, body composition from the gym, today's meals.
Our AI gathers your scattered health data and sends one line of coaching every morning.
JYLAB builds everyday tools on one principle: logging is automated, interpretation is AI's job, action is yours.
Unified health coaching that connects Garmin, Galaxy Watch, InBody body-composition and meal photos. Starting as a chatbot.
A smart coaster that changes your hydration habit. Connects to the AI coach.
A wearable GPS for amateur footballers. When the match ends, your data arrives.
An Android tool that tidies up your apps without replacing your launcher โ One UI stays exactly as it is.
15 questions, 5 minutes โ a Korean-tuned check-in that tells you your weekly type.
Try it now โ
Link your Garmin or Galaxy Watch account once โ activities, sleep and heart rate flow in automatically.
One when you eat, one when you measure body composition. Everything else is automatic.
Weight, muscle, sleep and diet are read together. No scaremongering over a single number.
Delivered to your messenger: exactly what to do today, nothing more.
The AI Health Coach starts as a private beta of about 30 users. The service is not a medical device and does not provide diagnosis or treatment advice. Health data is used only to provide user-requested coaching insights.
Activity, sleep, heart rate, body composition and meal photos โ only data you explicitly connect or upload. Garmin integration follows the official Health API user-consent flow.
We do not sell health data, use it for advertising, or share it with third parties. It is never used for anything other than your coaching.
You can disconnect integrations at any time, and we delete your data promptly upon request. Details in our Privacy Policy.
JYLAB is a one-person product studio in South Korea solving everyday problems with AI and automation. We ship a product only after the tool we built for ourselves becomes good enough.
The AI Health Coach started the same way: one person's automation for runs, body composition and meals is becoming a coach for everyone with the same problem.
Principles
Automated logging, data-driven interpretation, one-line conclusions. Health data is treated as sensitive information with data-minimization and purpose-limitation principles.
