AutoTreeGen - Your cousin's DNA holds the next step.
We show you
the branch.
Bring your tree and your DNA matches. AutoTreeGen finds where a cousin's line meets yours and proposes the branch beyond your brick wall, with the evidence behind it.
A cited record, connected to a person.
Illustrative lineage, not relationship proof.
1889 in a register. 1890 in a census. Both remain visible.
We tell you how each cousin is related to you.
Upload your match list from Ancestry, MyHeritage, FamilyTreeDNA or GEDmatch. AutoTreeGen predicts the relationship from shared DNA, sorts cousins into clusters on your family lines and shows the surnames each cluster carries.
Two kits see the same person. Your tree shows the branch.
Keep your own DNA kit and your relatives' kits in one AutoTreeGen account. When the same person appears in the match lists of two of those kits, AutoTreeGen shows the bridge and proposes the branch of your tree where that match belongs, as a hypothesis with its evidence.

Eight engines, one workspace.
An illustration with synthetic data: pick an engine to see the kind of output it produces. Names, places and numbers are invented.
Helga Vogt is recorded as the mother of Klara Müller.
Timeline impossible and DNA conflicts with maternity. The conflict and its evidence go to the researcher, who decides; the tree changes only on that decision, and the claim stays in the audit trail. Suggested correction - mother is Margarethe Weiss.
No fact without a source.
Facts imported with a source keep their citation, a confidence score and a provenance trail you can audit - and defend. Facts without one are marked unsourced, never dressed up as proven.
Your tree. Your evidence. Your DNA. Your decisions.
A connection is the beginning. Not the proof.
- 01
Bring your research.
Start with your GEDCOM. Add the records and DNA evidence relevant to your research.
- 02
Follow the evidence.
Explore people, sources and possible relationships together, rather than in separate silos.
- 03
Keep the disagreements.
A different date or an uncertain link is a question to investigate, not a detail to hide.
- 04
Make the decision.
Review the evidence. Keep a hypothesis open, reject it, or record your conclusion.
Already working, today.
Kits from different sites recognise the same person
A match seen on two platforms is proposed as one person - and nobody is merged without you.
One door for every DNA file
Ancestry, MyHeritage, FamilyTreeDNA, 23andMe, GEDmatch, AutoCluster ZIP - recognised by content, never by file name.
Haplogroups on the tree
The Y and mt lines read from your kits become a claim on the paternal or maternal line, shown where that line runs.
A conflicts queue where a person decides
Contradictions between sources wait in a queue, and a person closes each one: confirm, reject, keep it as a hypothesis, or override it with a reason on the record.
Provenance everywhere.
A fact here is an assertion, its evidence, and a computed confidence - never a bare name. Conflicts are versioned, not overwritten. The Fantasy scan flags people whose branches look invented, and says plainly that a flag is not proof. Our mtDNA reference carries all 5,371 haplogroups of PhyloTree Build 17 in van Oven's exact notation - and when a chip cannot distinguish subclades, we say so instead of guessing. Many of these instruments exist because researchers on genealogy forums around the world asked for them - endogamy-aware DNA, honest chip resolution, imports that hold at family-archive scale. Built to requests, not to trends.
Several trees become one
Preview the merge, resolve the conflicts, commit into a new tree. Your original files stay downloadable byte-for-byte, and every decision is kept.
Duplicates found and merged in bulk
The Duplicate Detective proposes pairs, and you accept them one by one or hundreds in a single action.
Branch Curator
Every branch outside the main tree, listed: keep it, attach it or delete it - and undo if you change your mind.
Your file, signed
Every GEDCOM the platform writes is identifiable and verifiable, and your original stays downloadable at any moment.
46 languages, and surnames found by sound
The app speaks 46 languages, and Daitch - Mokotoff phonetic search finds a surname however the clerk spelled it.
Built for the trees that break other tools.
Serious research outgrows casual software. AutoTreeGen's import pipeline is tested end-to-end at 350,000 persons - a real parse, real persistence - on demand, on our own hardware. Free and Pro carry 250,000 persons per tree (on Free the engines above 20,000 wait for Pro), Premium 500,000 - the same ceiling for everyone; above it, some engines still run on a sample until streaming catches up.
Your tree and your DNA stay yours. Secured, never sold.
Your tree and DNA live on our own dedicated servers, not in a shared cloud database, and travel only over encrypted connections. Raw DNA is encrypted before it touches the disk, and every DNA computation runs only behind your explicit consent. We never sell or share your data and never use it to train AI. AI features see only the fragment you ask about, never raw DNA. The one copy that leaves our servers is a nightly encrypted backup the storage provider cannot read. Export your tree whenever you like, and ask us to delete it and it is erased.
Plans built around evidence, not vanity
Four plans - Free, Starter, Pro and Premium. Free gives you a tree, 250,000 people, the GEDCOM Doctor and the Anti-Fantasy detector, no card required. Starter adds one DNA kit and your match list. Pro and Premium add full DNA and the advanced engines. Capability is the contract.
Paid plans renew automatically each month or year, on the period you choose, until you cancel. Cancelling stops the next renewal; you keep the plan until the end of the period you already paid for.
Pay by card through Stripe, or with PayPal.
Free is a working tier, not a trial.
We work with you, whatever you bring.
One tree or fifty DNA kits - the same attention. If your import is messy, we help you clean it. If your kits are spread across platforms, we help you bring them together. If you are stuck on one ancestor, that is a real question and it gets a real answer. Write to us and a person replies - not a ticket number.
Good questions.
Plain answers.
Research deserves transparency.
Read our trust & privacy policies ↗What file formats can I import?
Start with a GEDCOM exported from your genealogy tool. AutoTreeGen checks its structure and flags records that need attention.
How is DNA handled?
DNA requires explicit consent and careful handling. Read the current DNA privacy and consent policy before uploading your data.
What does confidence mean?
Confidence should be read alongside the supporting and conflicting evidence, not as a substitute for it. The methodology explains the approach.
Can I export my tree?
Your tree can be exported as GEDCOM. See the current product and plan information for research-report availability.
Where do I get started?
Create an account and start with your GEDCOM, or explore a worked example first.
More questions
Is my DNA data safe?
DNA is special-category data: encrypted at rest, never used to train models, and processed only under your explicit consent. You can delete it at any time.
How is confidence calculated?
Every claim is graded on its evidence - sources scored QUAY 1 to 3, DNA weighed against the expected range, agreement between records. Confidence is computed, not asserted.
Is it available now?
Yes. AutoTreeGen is open: create an account and import your GEDCOM. There is a feedback button in the top bar - tell us what breaks.

Give your family history a workspace where sources, DNA and decisions belong together.
