Genetic Voyage Research Tools
Explore our growing collection of free tools designed to help genealogists move from DNA matches and genetic evidence to structured research, hypotheses, and family-history discoveries.
🧬 DNA Match & Clustering Tools
Leeds Method Clustering Tool
Use the Leeds Method to group DNA matches based on shared-match patterns. Build a visual starting point for investigating which ancestral lines may be represented by different match clusters.
Leeds Auto Clustering Tool
Explore an automated approach to DNA match clustering. Use cluster patterns as a research aid when organizing matches and investigating possible ancestral groups.
DNA Relationship Probability Calculator
Enter shared DNA information and compare possible relationship categories. Use the results to develop and evaluate relationship hypotheses rather than treating a single estimate as proof.
DNA Chromosome Browser
Plot and compare shared DNA segments across supported chromosomes. Use segment overlaps to investigate patterns and potential triangulation as part of a broader DNA research process.
🧩 DNA & Genealogy Problem-Solving Tools
Genetic Genealogy Hypothesis Engine
Structure competing genealogical hypotheses and examine how DNA evidence and family relationships may support or challenge different research possibilities.
DNA Brick Wall Investigator
Work through challenging ancestry questions by combining DNA match evidence, family-tree research, hypotheses, and targeted research steps.
🌳 Family Tree & Genealogy Data Tools
GEDCOM Tree Viewer
Open and explore compatible GEDCOM family-tree data in a visual browser-based environment. Useful for reviewing family relationships while working through DNA and documentary research.
A Simple Genealogy Research Workflow
Different research questions call for different tools. A useful workflow is to move from planning and analysis to documentation and verification.
PLAN
Define the research question and use a checklist to decide what evidence and information you need.
ANALYZE
Use clustering, relationship, chromosome, and hypothesis tools to investigate the available evidence.
DOCUMENT
Record matches, segments, hypotheses, research steps, and findings in structured research templates.
VERIFY
Compare DNA findings with historical records, documented relationships, family trees, and independent evidence.

Frequently Asked Questions
Are these genealogy tools free?
The Genetic Voyage tools featured in the main sections of this page are provided as free research tools. Third-party services may have their own account requirements, limits, or paid features.
Do I need to install software?
The Genetic Voyage tools listed here are designed as browser-based applications, so they can be accessed online without installing traditional desktop genealogy software.
Can these tools prove a genealogical relationship?
No. Tools can help organize, visualize, compare, and evaluate evidence, but research conclusions require appropriate supporting evidence. DNA results should be considered alongside genealogical records and other independent evidence.
Which tool should I use first?
It depends on your research question. For DNA matches, you might begin with the Leeds Method or relationship calculator. For a difficult research question, the Hypothesis Engine or DNA Brick Wall Investigator may be more appropriate. Use the tool that matches the problem you are trying to solve.
Where can I find templates and checklists?
The Free Genealogy Research Kit brings together the main Genetic Voyage research resources, including free templates, checklists, and online tools.
Build a Better Genealogy Research Workflow
