AncestryLLM

AncestryLLM is a local-first platform for genealogy research tools. It combines deterministic RootsMagic and GEDCOM workflows with optional, explicitly selected LLM providers. The one-shot CLI and prompt-toolkit/Rich REPL are the only implemented product surfaces in 0.4.0. They derive commands from the same CommandSpec metadata and dispatch through the shared CommandExecutor into transport-neutral application services. The accepted local Electron and private FastAPI desktop architecture remains a later-roadmap adapter direction; it is unshipped and is not a public API.

Install and start

Python 3.12 through 3.14 and a working OS credential store are required. Install the isolated command with pipx:

pipx install ancestryllm
ancestry --version
ancestry --help

Install every optional LLM provider with pipx install 'ancestryllm[all-llm]'. Remote providers are never selected from installed packages or environment keys: every cloud call still requires an explicit profile and consent.

Run ancestry with no arguments for the prompt-toolkit/Rich interactive console. It is the only supported interactive console; the prompt stays responsive while background operations render live, sanitized spinner or completed-unit progress above it. One-shot and JSON output never emit terminal animation. The canonical command reference, examples, offline defaults, and privacy rules are in the CLI guide; see the console guide for interactive use and the file-ingress policy for per-format input limits and stable rejection codes.

Included modules

• rootsmagic: immutable, bounded SELECT/CTE queries and deterministic GEDCOM export.
• gedcom: merge, rooted subtree, quality analysis, incremental update, and rebase.
• prompts: immutable prompt revisions with declared variables and output schemas.
• people: curated research people, identifiers, facts, links, and provenance.
• providers: explicit Ollama, OpenAI, Anthropic, Gemini, and OpenRouter profiles.
• ocr: schema-validated extraction through the same provider boundary.
• secrets: no-echo OS-keyring management; values never appear in status output.

Development

git clone https://github.com/sodejm/AncestryLLM.git
cd AncestryLLM
make bootstrap
make test
make lint
make typecheck
make security
make sbom

make bootstrap creates .venv, installs the checkout in editable mode with locked development and provider dependencies, and installs lightweight commit hooks plus the canonical pre-push quality/security gate. Use make setup when automation needs the environment without modifying Git hooks. The equivalent manual install command is .venv/bin/pip install --editable '.[all-llm,dev]'; it is for contributors, not end-user installation.

The dependency graph is locked in uv.lock. Never commit real family trees, GEDCOM exports, databases, logs, reports, secrets, or research-person data.

Read the architecture, desktop ADR, CLI guide, privacy and consent, provider guide, GEDCOM compatibility, encrypted backups, bounded file ingress, CI workflow guide, and threat model.

Versioning follows Semantic Versioning 2.0.0. The versioning policy defines the CLI contracts covered by a release.

Interoperability status

Automated round-trip and preservation tests run in CI. Ancestry, Geni, and MyHeritage imports must still be manually smoke-tested for each release; this repository does not claim production interoperability until that checklist is completed and recorded.
