Research logs, Evidence Explained citations, GPS source quality ratings, and a searchable document vault — everything you need to practice rigorous, defensible genealogy.
AncestorOS is built around the Genealogical Proof Standard — so your research holds up under scrutiny.
Track every research session with structured logs: the objective, the repositories visited, the sources examined, the results found, and your conclusions. The paper trail that defends your work.
Templates for all major source types — vital records, census, military, land, church, and more — formatted to Elizabeth Shown Mills' Evidence Explained standard, the gold standard for genealogical citation.
Rate the reliability of each source using the Genealogical Proof Standard framework — original vs. derivative, primary vs. secondary, direct vs. indirect. Know how much weight each piece of evidence carries.
Upload scans of certificates, letters, photos, military records, and any other documents. Organize by client or family line, and link documents directly to citations and research log entries.
Professional research tools are included in the AncestorOS Pro plan at $40/month. Cancel anytime.
