Your Biology, Decoded
Your genetic data, supplements, and health journals—analyzed by private AI that never shares your information. Explore patterns and track what matters to you.
Why Stack Precision?
Most health apps track one thing. Your genetic test results sit in a drawer. Your supplement routine lives in your head. And nobody connects the dots between what you take and how you feel.
Stack Precision is the first app that brings genetics, supplements, and health journals together—then lets private AI find the patterns across all of it. You control exactly what data is shared, your information is never sold, and we follow HIPAA to protect it.
How It Works
Upload Your Genetics
Upload your raw data file from most consumer genetic testing and sequencing services. We scan for 194 specific variants and discard the rest.
Track What You Take
Build supplement stacks with flexible scheduling. Journal how you feel to spot patterns over time.
Get AI-Powered Insights
Ask your private AI assistant about your data. It never knows your name and you control exactly what it sees.
What You Get
- Supplement Tracking — Log daily intake, build flexible schedules, and track your supplement routine over time
- Genetic Profiles — Upload your raw data file from most consumer genetic testing and sequencing services and get a Genetic Profile across 19 health categories like methylation, detoxification, and vitamin metabolism. See our approach →
- Health Journaling — Record symptoms and daily wellness metrics to spot patterns between what you take and how you feel
- Private AI Chat — Ask questions about your data with AI that never trains on your data, sees your name, or knows who you are
- Community Trends — Opt in to see what supplements people with similar genetics are taking. Fully anonymized, always your choice.

Founder
After years of struggling with food intolerances, chronic pain, and doctors who couldn’t help, Jeff discovered that understanding his genetics was the key to resolving 90% of his symptoms. He spent tens of thousands of dollars and two decades in tech leadership—across startups, small businesses, and Fortune 200 companies—before building the tool he wished he’d had from the start.
