Threadline searches millions of historical records, newspapers, and archives — and writes your ancestors' story back to you, with sources.
Free early access for the founding waitlist · No credit card
Professional-genealogist thoroughness, without the professional-genealogist price tag.
Start with what you have — a parent, a grandparent, a name half-remembered from a family Bible. That's enough thread to pull.
Census rolls, ship manifests, parish registers, old newspapers — our research engine reads them the way an expert would, in minutes instead of months.
Not just a tree of names and dates — a written narrative of where your people came from and how they lived, with every claim cited to a real record.
Most family lines go dark two or three generations back — a burned courthouse, a changed spelling, an ancestor who seems to appear from nowhere. This is exactly the problem we built Threadline to solve.
“Wilhelm arrived in Baltimore in 1833 aboard a ship from Bremen. The passenger manifest lists his village — a detail that unlocks three more generations in the parish books back home.”
The founding waitlist gets first access when we open the doors — and helps decide what we build first.
Your direct ancestor line traced as far as the records allow, assembled and cross-checked against the original documents.
Your history as a story you can read aloud at the dinner table and pass down — not a spreadsheet of dates.
Each fact linked to the record it came from, so you can see the original census page or manifest yourself.
Tell us about the family line you want to trace — it takes about a minute.
