Positioning

A GEDCOM-based family-tree merge and visualisation tool. Parsing, merging, and persistence all happen in the browser; localStorage holds the active tree.

What it does

Imports GEDCOM files, reconciles people across sources, and renders a high-density tree view. Built on TanStack Start, React 19, and Vite 7, with Zustand stores for the active tree and an independent merge workspace.
