- GEDCOM round-trip
- Import and export with xrefs preserved. Tags we don't model yet are kept verbatim and travel back out — nothing is silently dropped.
- Dates
- Stored as GEDCOM strings — "ABT 1850", "BET 1800 AND 1810" — never coerced to timestamps, so partial and approximate dates survive.
- Evidence layer
- Sources, repositories, and citations with QUAY 0–3 surety grades, verbatim quotations, and supports/contradicts weighting.
- Living privacy
- No death date means treated as living, means private by default. Per-person overrides exist, and a deny outranks everyone — including admins.
- Review queue
- Propose, review, apply. Contributions from relatives, guests, and AI assistants all wait for the family's sign-off. Nothing overwrites silently.
- Guest research
- Person-scoped research projects give an outside collaborator exactly the people they need and nothing else.
- Bring your own AI
- Your assistant connects over MCP, reads what you can see, and files proposals. The platform makes zero AI calls of its own.
- Export
- Full GEDCOM and GEDZIP in every account state — trial, paid, and lapsed archive. Free forever.
