Artificial intelligence can find your ancestors up to the tenth generation - a hobbyist has created an open source skill for Codex and Claude Code, which helps to research family history on the territory of the former Soviet Union. Inside are instructions for working with records, military documents, repression and deportation cases. The agent takes into account old borders, changing names of villages and variations of surnames in different languages. For each find, the provenance is preserved, and names are cross-checked by relatives, dates, and even house numbers. We find distant relatives - here.
