Every EU country's laws, queryable with citations — compiles 12,000+ official statutes into a local Obsidian knowledge graph with inline source references. Runs entirely on your laptop.

your-ai-lawyer

A local-first RAG system that turns official government legislation repositories into a queryable Obsidian knowledge graph. Every answer comes with inline citations in the form [BOE-A-XXXX-XXXXX, Art. N] — traceable directly to the source statute. No API key, no cloud dependency, no subscription.

The Problem

Each EU country operates its own official legal database — BOE for Spain, Legifrance for France, Bundesgesetzblatt for Germany — with no unified query layer. Cross-jurisdictional research means juggling multiple portals and manually reconciling results. Commercial databases are expensive and subscription-locked. Government portals are free but isolated.

Architecture

git submodule (official law repos)
        ↓
  /compile <jurisdiction>
        ↓
  knowledge/ (Obsidian vault — wikilinked summaries)
        ↓
  /index → ChromaDB (summaries + raw article chunks)
        ↓
  /qa → prose answer + [BOE-A-XXXX-XXXXX, Art. N] citation

Law data arrives via git submodules pointing to official open-data repositories. Spain is wired up out of the box via the legalize-es submodule — 12,000+ laws from the BOE. Every other EU country is one git submodule add away.

Claude Code drives the pipeline through three slash commands:

  • /compile es-ct --limit 10 — reads raw laws, generates structured Markdown summaries with [[wikilinks]] to related statutes, writes into knowledge/
  • /index — builds two ChromaDB collections over compiled summaries and raw article chunks using ChromaDB’s built-in local embeddings
  • /qa "..." — retrieves relevant chunks, generates a prose answer with [BOE-A-XXXX-XXXXX, Art. N] inline citations

Key Features

  • Structural citations — every answer cites the exact statute and article, not post-hoc attribution
  • Navigable knowledge graph — compiled summaries are valid Obsidian notes with functional [[wikilinks]] between related statutes
  • Fully local — ChromaDB handles embeddings locally, no external embedding API needed
  • Incremental compilation — MD5 hashing skips unchanged files on subsequent runs
  • Multi-language output — English, Spanish, Catalan, French, Italian, German, Portuguese
  • 28 additional jurisdictions — EU member states, UK, Norway, US, and others, one git submodule add each

Technical Stack

  • Python with uv for dependency management
  • ChromaDB for local vector storage, retrieval, and embeddings
  • Claude Code slash commands as the compilation and query interface
  • Obsidian for knowledge graph navigation
