Your DNA, Organized. Your Ancestors, Found.
Upload your DNA test results from any company. Our app automatically groups your matches into Triangulated Groups and surfaces your likely common ancestors — no spreadsheets, no manual work.
"I had no idea that it would be as good as this. It's amazing! You are a star to have devised such an awesome DNA tool."
Works with raw DNA data from Ancestry, 23andMe, Family Tree DNA, MyHeritage, and LivingDNA
Your data stays yours · Request deletion anytime · Never shared with law enforcement
How It Works — Three Simple Steps
Upload
Download our free desktop app. Upload your raw DNA file — it takes 2 minutes. Add your family tree if you have one.
Discover
Our app shows you “Possible Triangulation” cards. Click one, and our engine confirms which of your matches truly share an ancestor with you.
Connect
You get a group with shared surnames, a private discussion forum to collaborate with your DNA cousins, and clues to your common ancestor.
Your Complete Journey — From Upload to Discovery
Create your free account
Download the desktop app and sign up with your email address. No credit card needed.
Upload your DNA test results
Works with raw data from Ancestry, 23andMe, Family Tree DNA, MyHeritage, and LivingDNA. Upload takes about 2 minutes.
Add your family tree
Upload a GEDCOM file if you have one, or build your tree inside the app. This helps the engine find connections faster.
See your DNA matches
Our engine scans your DNA against all other users and shows you everyone who shares significant DNA segments with you.
Explore "Possible Triangulation" cards
The app identifies groups of matches who overlap on the same chromosome segment — a strong signal of shared ancestry.
Click a card to confirm
Each card execution compares your matches pair by pair. Confirmed overlaps form a Triangulated Group — a group of people who share a real common ancestor.
See shared surnames and locations
Your Triangulated Group surfaces shared surnames from family trees, geographic hints, and links to each member’s tree.
Discuss in your private forum
Each Triangulated Group has a private discussion forum where you and your DNA cousins can share research and collaborate.
Identify your common ancestor
Together, work out who the Most Recent Common Ancestor is — the couple or individual you all descend from.
Add more matches with "Confirm Cousin"
As new matches appear, use "Confirm Cousin" cards to add them to existing Triangulated Groups and strengthen your findings.
Earn points on the scoreboard
Each confirmed ancestor earns you Common Ancestor Points. See how you rank on the public scoreboard alongside other genealogists.
Visualize your inheritance
Generate Chromosome Maps to see which DNA segments you inherited from which ancestor — a visual map of your genetic heritage.
Your Data, Your Rules
Your DNA data sits on enterprise-grade cloud infrastructure (Oracle Cloud), governed by Singapore's Personal Data Protection Act — one of the strictest privacy frameworks in the world.
Never shared with law enforcement
Unlike some competitors, we never provide your data to police or government agencies. Your genetic information is strictly private.
Request data deletion anytime
Your data belongs to you. Click the Help button and open a ticket with our Customer Care team. We will remove your data within 30 days, carefully ensuring shared records are handled correctly.
Your email is never shown or sold

Built by a Genealogist, for Genealogists
Hi, I'm Andreas West, the founder of yourDNA.family.
I started building this app because I was frustrated spending my weekends in spreadsheets, manually comparing DNA segments. I wanted to leave the boring, repetitive work to computers and focus on working with my DNA cousins to find our common ancestors.
I also want to make it a lot easier for everyone to get the most from their DNA test, without needing a PhD in Biology or years of studying this complicated topic. With your support, I hope I will succeed in this mission.
What Our Members Say
“I have just gone back in and have opened my TG. I am completely blown away by the way it is and can immediately see a surname which is where I think we connect. I have been looking for many years for my birth father as I was adopted at three months old. I had no idea that it would be as good as this. It's amazing! You are a star to have devised such an awesome DNA tool.”
“Today I solved a large triangulated group on my X chromosome, with the help of your DNA family. Before, I knew which of my great-grandparents had given me this segment, now I know its two more generations back, and have identified 3 new distant cousins. The way your DNA family collects the information by triangulated group is really helpful, and clearly presented.”
“YourDNA.family is a wonderful application that has helped drive my research. I love how the app does all the heavy lifting of organizing all the data I need into Triangulation groups, so that I can focus on the fun part of figuring out how cousins connect into my ever expanding family tree.”
“I enjoy working with YourDNA.Family because it allows me to focus on my genealogical research while the program automates repetitive functions that would otherwise take months to accomplish! It has helped me to confirm cousins on my paternal and maternal sides, ending the guess work that has puzzled me for years!”

Frequently Asked Questions
Who built this and why?
My name is Andreas West, the founder of yourDNA.family. I started building this app because I was frustrated spending weekends in spreadsheets, manually comparing DNA segments. I wanted to leave the boring, repetitive work to computers and focus on working with my DNA cousins to find our common ancestors. With your support, I hope to make DNA genealogy accessible to everyone.
Is it really free to get started?
Yes! You can create an account, upload your DNA test results, and explore your matches completely free. We give you free credits so you can try all the premium features — like confirming DNA cousins and building Triangulated Groups — at no cost.
What DNA test results work with this?
Our app works with raw DNA data from Ancestry, 23andMe, Family Tree DNA, MyHeritage, and LivingDNA. We focus on autosomal DNA — that’s the type that helps you find cousins and ancestors on all branches of your family tree.
Where is my data stored and who can see it?
All data is stored on enterprise-grade cloud infrastructure (Oracle Cloud), governed by Singapore’s Personal Data Protection Act (PDPA). Your email is never shown to other users and never sold. We never share your data with law enforcement or third parties. To request data deletion, click the Help button and open a ticket with our Customer Care team — we process all requests within 30 days.
How is this different from GEDmatch?
GEDmatch requires you to manually compare segments and build triangulations yourself — a process that can take hours of spreadsheet work. Our app does this automatically. Upload your data, and our engine groups your matches into Triangulated Groups, surfaces shared surnames, and identifies likely common ancestors. Plus, each group has a private discussion forum where you can collaborate with your DNA cousins.
Can I delete my data?
Yes, absolutely. Click the Help button on any page and open a ticket with our Customer Care team to request deletion. We carefully remove your DNA data, family tree, matches, and account within 30 days — taking care to handle any records shared with other users.
