You got your DNA results. Now what?
Most testing companies hand you a raw VCF file — or charge extra for a report. We're scientists who think the step in between should be freely available: upload your file and we'll annotate it against public databases, adding frequencies, known associations, and database IDs so you can search and explore your own data without looking up every variant by hand.

What's actually in your file
Most providers hand you a VCF file — Variant Call Format. A variant is simply a small difference between your DNA and the reference human genome, the standard "template" copy scientists compare everyone against.
Imagine someone handed you a list of every word where your copy of a book differs from the original edition — page numbers, the old word, the new word — and nothing else. No note about which changes matter, which are typos, and which everybody else's copy has too. That's a raw VCF file.
Usually your choice is to pay for a report or wrestle with the raw file yourself. We wanted a third option: a free, annotated file you can actually search and explore.
A few lines from a typical file
#CHROM POS ID REF ALT 1 11856378 rs1801133 G A 6 26091179 rs1799945 C G 10 94781859 rs4244285 G A 12 21331549 rs4149056 T C
Every row is one difference. Nothing here tells you what any of it means — that step is called annotation, and it hasn't happened yet.
We look up the details so you don't have to
Annotation means matching each of your differences against what scientists have already published and adding that information to your file. You get back an annotated file — not a finished medical report — but one where frequencies, database IDs, and known associations are filled in. That lets you search for a gene or keyword and see what's known, without researching every variant by hand.
How common it is
Population frequencies — how many other people carry the same difference, added as data for each variant. Many turn out to be shared by millions of people.
What it's been linked to
Database identifiers and known associations from the research literature, attached to the matching variants. How strong that evidence is varies a lot from variant to variant.
Medicine-response hints, where known
Some variants have been linked to faster or slower processing of certain common medications. The evidence varies a lot, and any medication decisions belong with your doctor.
Curious about a specific result? Every variant in your report links out to SNPedia, a free, community-run wiki where you can look up almost any SNP by its rsID and see what the research literature says — a good next stop once something in your report catches your eye.
How it works
Upload your file
Drag in your .vcf or .vcf.gz file. It goes straight into private storage that only your account can open.
We annotate it in the background
This can take a while — minutes for small files, a few hours for whole genomes. Close the tab; we'll email you the moment it's done.
Search it, or download it
Your VCF comes back with the annotations filled in — frequencies, database IDs, known associations. A whole-genome file can run to millions of rows, well past what Excel or a text editor can comfortably open, so we built a search built right into the page: look up a gene, an rsID, or a condition and see what's known, right where the variant is. The full annotated file is also yours to download any time, no strings attached.
How your data is handled
Genetic data is personal, and we treat it that way. No buried clauses — just what actually happens to your file.
- Your file is encrypted in storage and only reachable through your own signed-in account.
- We never sell your data, share it with insurers or employers, or use it to train anything.
- You can delete your file and every result generated from it at any time — permanently, not just hidden.
- We only email you about your own uploads. No marketing lists.
Questions people ask
Search your file — see it before you upload anything
The moment your file is annotated, a search box lets you type a gene, an rsID, or a condition and get an answer in seconds — no spreadsheet, no scrolling through millions of rows. Here's exactly the kind of thing it turns up: real public research, quoted as-is from SNPedia. Upload your own file and the same search shows your own genotype for questions like these, not just the general science.
That's really all it takes — type a few letters, get an answer.
Does cilantro taste like soap to you?
OR10A2
The A allele of rs72921001 is linked to a lower chance of perceiving cilantro as soapy-tasting — a real, measurable difference in how people experience the same flavor compound.
Wet or dry earwax?
ABCC11
One SNP in the ABCC11 gene decides this — and it's also linked to how much you sweat. It's commonly the (T;T) genotype in East Asian populations, versus (C;C) in European and African populations.
What decides blue vs. brown eyes?
HERC2 / OCA2
A single SNP near the OCA2 gene lowers its activity enough to change eye color outright — the (G;G) genotype at rs12913832 is strongly linked to blue eyes.
