An OC family tree maker is a tool for organizing original characters — mapping each OC’s parents, siblings, romances, and found family so your lore stays consistent as the cast grows. It replaces the pile of notes-app fragments with one canvas where every relationship between your OCs is drawn and easy to update.
Built for this kind of family
Ships and dynamics
Draw romantic pairings, rivalries, besties, and enemies-to-lovers arcs as actual relationship lines between OCs.
Found family counts
Adoptive bonds, chosen family, and mentor relationships have their own line styles — blood is optional.
Grows with your cast
Twelve OCs or two hundred — generational layout keeps the canvas readable as the roster expands.
Share your lore
Export a clean PNG for your carrd, toyhouse, or art commissions — or share a live link with friends.
How it works
Add your main OCs
Start with the characters you already know, names and pronouns included.
Connect the lore
Parents, siblings, ships, found family — every bond becomes a line on the canvas.
Keep it canon
When lore changes, update the tree — it becomes the single source of truth for your universe.
Frequently Asked Questions
What is an OC family tree?
It is a chart of the relationships between your original characters — biological family, adoptive and found family, romances, and rivalries. Keeping it as a live diagram (instead of scattered notes) keeps your lore consistent as you add characters and develop their stories.
Can I include found family and adopted OCs?
Yes — adoption and chosen-family bonds have their own line styles, distinct from biological parentage. Many OC trees are mostly found family, and the chart stays readable either way.
Can I share my OC tree?
Export a clean PNG free for your profiles or commission sheets, or publish a view-only link so friends can explore the whole tree interactively.
Do I need to know genogram symbols?
No. The editor applies correct notation automatically — you just add characters and pick relationship types. If you want the full symbol vocabulary for richer lore, the genogram symbols guide covers every line and marker.
