What your genome actually says

Understand your genome,
without it ever leaving your machine.

MyGeneLog reads a raw genome file (VCF, or a 23andMe/AncestryDNA export) on your own machine and explains what a small set of well-studied variants actually mean — the conditions they are linked to, the medicines they change, even what you can smell and taste. Plain language, every claim sourced, nothing uploaded anywhere.

How it works

Everything below happens on your own computer. No account, no cloud, no upload step.

1. Open your file

Point MyGeneLog at a raw VCF, or a 23andMe/AncestryDNA export.

2. It's parsed in memory

Matched against a small, hand-curated reference dataset — nothing is sent over the network.

3. Read your results

Plain-language findings, each with a "see detailed info" link to a page like the ones below.

What MyGeneLog checks for

Every finding gets its own page — the same wording the app and your exported PDF report show. 62 variants and growing.

What we're building

Genetics information online is either precise but impenetrable, or readable but thin — and usually locked down. We're building the reference that's both: accurate enough that a clinician finds nothing to correct, clear enough that anyone can read it, and open enough that anyone can reuse it.

Variants

What specific, well-studied positions in your genome actually mean — genotype by genotype, with the research cited.

Browse variants →

Conditions

What a disease is, its symptoms, how common it really is, and which variants have a genuine, replicated link to it.

Browse conditions →

Drug response

Where research shows your genetics can change how a medicine behaves — described honestly, never as a prescription.

Browse drugs →

Smell & taste

The rare place where a variant does not shift a probability but changes what you perceive. Two people meet the same molecule and one of them smells nothing.

Nothing is uploaded, ever. Your genome file is parsed in memory, on your own computer — the opposite of a cloud DNA service. Read the privacy policy →

What is MyGeneLog?

MyGeneLog is a free, open reference for genetic variants, the conditions they relate to, and how genetics can affect drug response — plus a free Windows app that reads your own raw genome file offline and explains what it finds in plain language.

Is MyGeneLog free?

Yes, completely. There is no account, no subscription, and no license key. Donations are welcome and cover hosting and research, but nothing is required to use the app or read the site.

Does my DNA data leave my computer?

No. Your genome file is parsed in memory on your own machine and is never uploaded, stored, or transmitted. There is no server-side genome processing at all — the privacy comes from the architecture, not from a promise.

Which files does MyGeneLog work with?

Raw VCF files, and raw data exports from 23andMe and AncestryDNA. If you tested years ago and still have the download, it will work.

Is any of this medical advice?

No. MyGeneLog is informational only and does not diagnose, predict, or recommend treatment. Genetics shifts probabilities rather than deciding outcomes — for what a result means for you, talk to a doctor or a licensed genetic counselor.

Ready to see your own results?

The app is free and the reference is open. Donations cover hosting and the research behind every new variant, condition, and gene–drug page.
