Testing Gedminer

 

Gedminer. June 2026.

On Jarrett Ross' Friday YouTube livestream, he demonstrated a new tool called Gedminer. It is browser-based, and currently free to use (although you can donate to the developer to support the project). Gedminer works with a GEDCOM (a structured file for storing family tree data) and provides a detailed analysis with suggestions for further exploration. Some screenshots below capture what Gedminer can do.

You can download a copy of your GEDCOM from Ancestry or MyHeritage, and upload it to Gedminer. The process was fairly easy, although it did take me a little bit of time to find the right place to generate the GEDCOM file on Ancestry.

Under the heading "Discovery", Gedminer has tabs for deep dives into your GEDCOM data, including Migration Analysis, a Census Toolbox, Gap Detector, Incomplete Families, a DNA Planner, and Plan Generator. The Migration Analysis is very cool.

The Plan Generator analyzes the GEDCOM and suggests highest impact research tasks.

I am going to try some tree cleanup on Ancestry and fixing of suggested errors, and then reload the updated GEDCOM. Gedminer can show progress improvements and recalculate scores. This looks like a very powerful tool.
