Get started instantly by adding characters, connecting parent-child and partner relationships, and organizing generations with our easy to use & intuitive family tree maker. Export as images or other formats (JSON, Markdown, or plain text) to have offline & printable backups of your trees.
Whether you're crafting a fantasy novel, developing original characters, or running a campaign; our family tree builder helps you manage complex relationships that most genealogy apps can't handle: adopted heirs, secret lineages, blended families, and multi-generational dynastic webs that span centuries.
Map character genealogies for novels, series, and screenplays — built around storytelling, not birth records.
Visualize relationships across your fandoms and original universes with an OC-friendly character tree builder.
Create dynasty charts, noble house trees, and NPC lineages for richer, more consistent campaigns.
Design fictional civilizations with bloodlines, succession chains, and multi-generational webs that feel real.
Unlike traditional genealogy software, everything runs entirely in your browser — nothing to install and no account needed to get started for free.

The core family tree builder is free to use and works without an account. You can always upgrade at anytime for multiple trees, unlimited characters, cloud sync, advanced export options and other premium features.
