AncestorOS analyzes the information in your tree and surfaces what you might have missed — estimated dates, research gaps, and patterns in your family history.
When birth or death dates are missing, AncestorOS can estimate them from related events using well-known demographic patterns. A person who married in 1870 was likely born between 1840 and 1855. Helps you prioritize research without guessing blindly.
AncestorOS scans your tree and flags people who are missing key information — no birth place, no parents, no marriage date. Research gap alerts tell you exactly where to focus next instead of wandering through your data.
Family patterns emerge when you have enough data: naming conventions across generations, geographic clusters, occupational trends. AncestorOS helps you see them — not as speculation, but as analysis grounded in what's actually in your tree.
The more you add, the more AncestorOS can analyze and surface.
Build your tree normally — names, dates, places, relationships. Every piece of data you add becomes material for analysis.
In the background, AncestorOS checks for date gaps, missing fields, cross-referenced relationships, and statistical patterns. All analysis is done on your data only — no external databases.
Review each discovery, act on it (add the estimated date, fill the gap), or dismiss it. Your tree gets richer with every action.
No hallucinations. No guesses. Only analysis from what you've actually entered.
Derived from relationships using established demographic patterns. Never invented — always traceable to source events.
Missing birth places, parentless individuals, incomplete marriages — surfaced automatically so nothing falls through the cracks.
Naming conventions, geographic clusters, occupational trends — patterns across generations made visible.
Every discovery is based solely on data you entered. We never fabricate records, invent ancestors, or connect to external databases.
The more people and events you add, the more patterns become visible. Discoveries improve as your tree grows.
Complete research gap alerts, date estimation, and pattern analysis are included in both Hobbyist and Pro plans.
Free plan includes basic gap alerts. Build your tree and watch discoveries appear.
