How do I visualize my 23andMe or AncestryDNA data?
Buy Chromly, open chromly.app/app in a recent Chrome, Edge, or Firefox, and drag your raw data file straight onto the page. Chromly auto-detects the format and starts rendering. No conversion, no waiting room, no upload step. Your file is read directly from your disk by the browser.
Is my DNA actually private? Where does the file go?
Your file goes from your disk into your browser's memory and that's it. There is no Chromly server that sees raw genotype data. If you choose to save your loaded genome inside the app, it's written to your browser's Origin Private File System, which is sandboxed to your device. The longer version lives on the science page and in the privacy policy.
Which file formats work?
Raw data from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, and Living DNA. Plus standard VCF files from clinical sequencing. Chromly figures out which one it's looking at; you don't have to convert anything first.
What are TADs and why does Chromly show them?
TADs are topologically associating domains. Think of them as neighborhoods inside each chromosome where DNA interacts with itself a lot and almost never reaches across the boundary. They're how your genes get reached by their regulatory elements. Chromly folds each chromosome around real TAD boundaries from published Hi-C studies, so the 3D shape isn't decorative. The science page covers what's data-grounded and what's procedural in that render.
Is Chromly a medical or clinical tool?
No. Chromly is for personal exploration and learning. We don't predict disease risk, prescribe anything, or replace a doctor or genetic counselor. If you want a clinical-grade read of your raw data, the National Society of Genetic Counselors can connect you with someone credentialed.
Does Chromly work on mobile?
It opens on mobile, but it's built as a desktop-class WebGL experience. The 3D viewer wants a real GPU, a keyboard for WASD, and screen real estate. A modern laptop or desktop is the right form factor.
Do I need to make an account?
No account, no sign-in. Buy once, get a license key, paste it in. That's the entire onboarding.
What if I switch to a new computer?
Your license key works on more than one machine. Re-enter it on the new device and reload your raw DNA file (it lives on your computer, not ours, so you'll need the file itself). Your saved profile stays on whichever device you set it up on. There's no cloud sync, by design.
