ARV
ARV helps you find the people who belong to your family's story. Start with one name: it searches open Swedish archives and community trees, shows where each lead comes from, and never turns a lead into a fact until you have checked the original.

Codex
- What I built
- I built it with Codex: the archive search across open sources, the family graph and tree, the evidence and privacy rules, and the demo with a made-up family.

The family network in the demo. The Sjöberg-Lindgren family is made up.
How it works
- 01
It searches open sources with no key: Riksarkivet's church-record index, the Swedish Biographical Lexicon and the seamen's-house registers, plus the community trees WikiTree and Wikidata.
- 02
A hit is a source record, not a relative. Parents and siblings from a community tree are shown as leads to check against the original, and nothing enters the family tree automatically.
- 03
Living people stay private: the open search only covers people born more than 111 years ago, or 70 if you confirm that the person has died.
- 04
Every search says what came back: a real hit, a real zero or a technical error, never a made-up result.
- 05
The demo runs on a made-up family of 38 people from 1824 to 2019, with no accounts and nothing stored.
- Decision 1
A lead is not a fact: every family link needs the original and an independent check.
- Decision 2
Privacy first: living people are never sent to external sources.
- Decision 3
Say what came back, including nothing, instead of guessing.


Happy to walk through the thinking, the trade-offs and where it's headed next.
