CatFox Genea

A modern, lightweight, offline genealogy app, focusing on displaying and managing a clean, direct ancestor line.

Designed for clarity

Many genealogy tools try to model every possible relationship and manage every workflow.

CatFox Genea takes a different approach:
It focuses on managing and displaying a direct ancestor line, with navigation that remains readable even as your tree grows.

Expand generation by generation, without having your displayed family tree devolve into a confusing mess.

Built to feel modern

Smooth interactions, responsive navigation and a clean visual language. CatFox Genea is made to react instantly and stay out of your way while you work.

The interface remains consistent throughout the application. Editing, reading and navigating follow the same visual structure.

No visual overload. No unnecessary friction. Just a focused desktop experience.

Key features

Cluster-based tree

The tree is organized into clusters of 4 generations. To keep navigation easy, and your steps retraceable.

GEDCOM compatible

Bring existing data in, or export your work as a GEDCOM file at any moment. Your data stays yours.

Media attachments

Attach files like documents or photos to people. Add a profile picture to make someone in the tree easier to recognize.

Project folder

Everything you need is stored in a single folder you choose. It contains the database, backups and media, so you can move your project anytime.

Built-in backups

Control your backups directly inside the app. Three quick-access slots keep the process simple.

Local, offline-first

Your data is stored locally on your device. CatFox Genea is fully functional without an internet connection.

Person search

Quickly find people by name and jump to their position in the tree, automatically expanding the appropriate clusters.

Direct ancestor focus

CatFox Genea intentionally avoids modelling large side-branches. The main goal here is clarity: build a readable ancestor line.
