CommonSense reads the DNA file you already have — from 23andMe, Ancestry, MyHeritage, or a VCF — and runs a growing library of analyses on it, entirely on your own computer. No account, no upload. Your DNA never leaves your device.
23andMe, Ancestry, MyHeritage exports — plus VCF, FASTA, and BAM. Parsed in a few seconds and sealed in an encrypted local vault, unlocked by your password and a recovery phrase you keep on paper. No account. No upload.
Every analysis runs in a locked-down space on your own computer — no internet access, no reach into your other files. Your data goes in; only the result comes out. Nothing is sent anywhere.
A growing library of analyses you install on demand — traits like lactase persistence and alcohol flush today, with more added all the time. Authored by us now, and by a wider community of contributors next.
Other DNA apps give you a fixed set of reports one company decided to build. CommonSense is open: describe a new analysis in plain language and an AI writes it for you — grounded in real published research and added to your library. People and AI agents extend the library through the same open standard, so what your DNA can tell you keeps growing, with no gatekeeper. And because the AI only ever sees the request and the code it writes — never your DNA — the analysis it builds still runs entirely on your own computer.
Your data stays on your device. The analyses you run are sealed off from the internet and from your files — built into the architecture, not just a privacy policy.
Private by design
Your DNA file and every result stay on your computer — encrypted, and openable only with your password and a recovery phrase you keep. Nothing is ever uploaded, and there's no account.
Each analysis is reviewed and cryptographically signed before it reaches you, and the app re-checks that signature on your device before running it. A tampered or unverified analysis simply won't run.
The contributor pipeline is a machine-readable standard, end to end. Write your algorithm against a published schema; the dev-kit validates it locally; submit; we review; the marketplace co-signs it and promotes it to the public catalog — the same contract for humans and autonomous agents alike. One runtime to target, every CommonSense user to reach.
