Instant Analysis
Results in seconds, no signup required
Get an instant snapshot of your family tree with gender breakdowns, date ranges, generation counts, and family size distributions. See how your genealogy data stacks up at a glance.
Browse every individual in your GEDCOM file with fast search, surname grouping, and sortable columns. Jump to any ancestor instantly.
Visualise where your ancestors lived on an interactive map. Cluster locations, explore place hierarchies, and see geographic patterns across generations.
Discover what your ancestors did for a living. Group occupations by category, spot trends across generations, and understand the social history of your family.
Calculate the exact relationship between any two people in your tree. Find shared ancestors, explore relationship paths, and estimate shared DNA.
Start from what your tree is missing rather than a blank search box. Suggestions are drawn from the gaps and patterns in your own data, and the Source Explorer shows which facts are actually backed by a source and which are not.
Automatically scan your GEDCOM file for common errors: impossible dates, missing parents, duplicate entries, and data inconsistencies. Identify issues before they affect further research.
Identify individuals with vague or estimated dates and prioritise which records to sharpen first based on research impact. Missing deaths are called out separately, because an ancestor with no recorded death is often one of the quickest records to investigate.
Find family units that look like they are missing children. Marriage spans, the gaps between recorded births and the length of the reproductive window are compared to show which families are probably incomplete rather than simply small.
See your tree as a structure rather than a list. GEDminer finds the separate islands in your file, the people connected to nobody, the entries that are probably the same person twice, and the clusters that look like the same family recorded in two disconnected branches.
Trace your family’s movements across countries and continents. Visualise migration routes, identify immigration waves, and explore when and where your family moved.
Find missing census records for every ancestor. Cross-reference known dates with census years to reveal exactly which records you should be searching for.
Spot gaps in each ancestor's timeline where life events are missing. Find the decades where records might exist but haven't been found yet.
Work out who in your tree was the right age, in the right place, to have served in a given conflict - then go straight to the archive that holds those records, instead of searching every name against every war.
Strategically plan which family members to DNA test for maximum genealogical value. Identify the oldest living relatives and key lineage branches.
Automatically generate a prioritised research plan based on the gaps, errors, and opportunities in your tree. Know exactly what to research next.
Re-uploading a tree you have been working on elsewhere should not be a leap of faith. Compare the new file against the saved one first and see exactly who is added, who has gone, and what it does to your tree health before anything is overwritten.
Our step-by-step guides walk you through GEDCOM analysis, census research, DNA testing, and more.
