Relationship Calculator
Enter the shared centimorgans from a DNA match and see plausible relationship classes with the reasoning shown. No upload. No account required.
Try it now →Trust & Evidence
Tools support research. Evidence decides the conclusion.
Roots Adventure tools are built to keep facts, interpretation, and hypotheses separate so your family story stays careful and defensible.
Suggestions aren’t facts
Calculator output and generated plans are leads to test, not proof of a family relationship.
Confidence is shown honestly
When a tool cannot support certainty, it says so plainly and keeps competing possibilities visible.
Private data stays under your control
Public tools avoid raw DNA uploads, unnecessary living-person details, and fake account storage.
Guided workflows
Start with the step that is ready.
Workflow collections show how the tool library will grow. Only available steps open today.
