Question 1

Is this a DNA reader?

Accepted Answer

Yes — it's a free online DNA reader that opens your 23andMe, AncestryDNA, or MyHeritage raw data file and shows well-known markers instantly. It runs entirely in your browser, so your genome is never uploaded.

Question 2

Can it read an AncestryDNA or MyHeritage file too?

Accepted Answer

Yes. It auto-detects 23andMe, AncestryDNA, and MyHeritage raw data — the .txt or .csv file you download from your test — reads the genotypes, and matches a set of well-studied markers. If your file is a .zip, unzip it first.

Question 3

Is it free and private?

Accepted Answer

It's completely free, and private by design: the file is read locally with your browser's FileReader and nothing is sent to any server. Close the tab and it's gone.

Question 4

How do I get the raw data file to read?

Accepted Answer

Download it from your testing account — see our guides on downloading your 23andMe, AncestryDNA, or MyHeritage raw data. Then drop the unzipped .txt or .csv into the reader above.

Question 5

Is this a free DNA analysis tool?

Accepted Answer

Yes — it's a free DNA analysis tool for your raw data. Upload a 23andMe, AncestryDNA, or MyHeritage file and it analyzes well-known markers instantly, at no cost and with no account. Unlike most free DNA upload sites, nothing leaves your device — the analysis runs entirely in your browser, so you get a free analysis without handing your genome to a server.

Question 6

Can I analyze my DNA for free without uploading it anywhere?

Accepted Answer

That's exactly what this does. Most 'free DNA upload' sites require you to send your raw data to their servers; here the file is analyzed locally with your browser, so you can analyze your DNA for free while it never leaves your device. It's the private alternative to uploading your genome to a third party.
