Stringboard
A detective-style case wall. Pin people and stories as cards, run red thread between them, and name what each connection actually is. Keep as many boards as you want, drag from a card's dot to another to link them, and back up or restore the whole thing as a file. One self-contained HTML file. Everything stays local.
