The library
of your
lineage.
AutoTreeGen is a working archive for serious genealogy. Every name, every date, every DNA segment is bound to a citation, a confidence score, and a chain of provenance you can defend in print.
Genealogy is not a hobby. It is the guesswork evidence we owe to the people who came before us — and the ones who come after.
Cite, or it didn't happen.
Every fact traces back to a source — a parish register, a census line, a centiMorgan segment. Unsupported claims are stored separately, as hypotheses.
QUAY 1 · 2 · 3Disagreements are versioned, never overwritten.
Two cousins, two birth years, two scribes' hands. The archive keeps all of them. Confidence is computed, not asserted, and updates with new evidence.
audit trail · permanentPaper and DNA, in one workspace.
Y-DNA, mtDNA, autosomal cM segments and your scanned records sit in the same tree. The engine reads both at once.
Any GEDCOM · strictAn archive that thinks in centuries.
Eight lineages, four generations, one diagram.
The signature ribbon-tree: each branch carries its lineage colour from root to tip, with portraits attaching where photographs survive.
Confidence as a number, not a feeling.
The hypothesis engine scores every proposed link and shows which evidence raises it and which lowers it.
QUAY-graded provenance.
Sources are graded on a 1–3 scale. A link is confirmed only at QUAY 2 or higher.
Y, mt, and autosomal in one view.
Three evidence streams — paternal line, maternal line, recent cousins — overlay on the same tree.
Do not build trees of names. Build trees of evidence.— the founder
No fact without a source.
Every name, date and DNA segment is bound to a citation, a confidence score and a provenance trail you can audit — and defend.
Eight engines, one workspace.
Pick an engine to watch it run on a sample tree — the names and places are synthetic.
Helga Vogt is recorded as the mother of Klara Müller.
Timeline impossible and DNA excludes maternity. Claim removed from the canonical tree, kept in the audit trail. Suggested correction — mother is Margarethe Weiss.
Your evidence, being assembled.
From GEDCOM and DNA to a defensible tree.
Import
Drop any GEDCOM file — from Ancestry, MyHeritage, Geni, any version, any size. We parse it strictly and tell you which records bend the spec.
Any GEDCOM · any sizeMatch
Add Y, mt and autosomal kits, or your exports from Ancestry, MyHeritage and GEDmatch. Each kit becomes its own evidence stream.
cM · segments · haplogroupsHypothesise
The engine proposes parent–child links, scores them, and records the evidence both for and against.
confidence ∈ [0, 1]Cite
A finding is confirmed only with at least one QUAY-graded source.
QUAY 2+ to confirmWhat the engine actually does.
It checks the evidence
Every proposed link is scored against the records and DNA behind it; anti-fantasy detectors flag the fabricated and the over-reached.
It keeps the chain of sources
Each fact stays bound to its citation — parish register, census line, DNA kit — graded QUAY 1 to 3.
It accounts for DNA
Y-DNA, mtDNA and autosomal cM read alongside the paper trail, with endogamy weighed in so shared segments are never over-read.
It tracks conflicting hypotheses
When sources disagree, both are kept and versioned. Confidence is computed from the evidence, never overwritten.
It generates research reports
Findings, evidence and open questions compile into a defensible report you can export.
Plans built around evidence, not vanity
Three plans — Free, Pro and Premium. Free is a real working tier: a tree, 5,000 people, the GEDCOM Doctor and the Anti-Fantasy detector, no card required. Pro and Premium add full DNA and the advanced engines. Capability is the contract.
Questions, answered plainly.
What file formats can I import?
Any GEDCOM — from Ancestry, MyHeritage, Geni or any other tool, any version. We parse it strictly and flag the records that bend the spec.
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.
Can I export my tree?
Yes. Your tree exports back to GEDCOM, and its findings compile into a PDF research report.
Is it available now?
The methodology and worked examples are public today. Entry opens at launch.
