Visual tools for turning DNA matches into family-history clues.

DNA Painter helps genealogists interpret DNA match information through chromosome maps, relationship calculators, and family-tree-based probability tools. Users can map shared DNA segments to known ancestors, explore possible relationships from shared centimorgan amounts, and build visual pages for direct ancestors.

Why it stands out

  • Focuses specifically on the interpretive step after DNA testing, rather than selling tests or hosting record collections.
  • Combines segment mapping, shared-cM interpretation, and tree-based hypothesis testing in one genealogy-focused workspace.
  • Includes learning materials and walkthroughs aimed at users who are new to chromosome mapping.
  • The example chromosome map lets visitors try the interface without saving or risking their own data.

Good to know

  • Requires DNA match information from another testing or matching service; it is not itself a DNA testing company.
  • Some workflows depend on having known matches that can be placed into a family tree.
  • The site explicitly asks users not to send raw DNA by email, so support is not a place to transfer genetic files.
  • Free registration is available, but the site also offers subscriptions, so some capabilities may sit behind paid access.

Under the radar: Use the example chromosome map on the homepage to try moving and deleting segments; changes are not saved, so it is a safe way to learn the mapping workflow before creating your own map.
