Turn one family name into a living history.
Choose a name, an era, and a creative direction. Tsumugen grows them into an AI-generated family tree, character records, and timelines you can explore.
No credit card required / start with only a family name
A creative archive in three steps
Tsumugen is built for people who want to explore a lineage, not fill out a database.
Set the premise
Enter a family name, a starting year, and whether the world should lean historical or fictional.
Generate the founder
The first person, family context, and early turning points are created as the root of the tree.
Read the records
Open people, continue generations, and follow the family through tree views, wiki records, and timelines.
Not genealogy software. A story engine for lineages.
Use it for historical imagination, worldbuilding, fiction prep, tabletop campaign material, or simply to watch generations change over time.
Your family history is still blank.
Start with one founder, then follow the lineage wherever it goes.
