What Legal Data Hunter does

Legal Data Hunter connects ChatGPT to the world's fastest-growing open legal corpus — a continuously-updated index of 32M+ documents from 180+ jurisdictions. LDH ingests directly from official registries — Légifrance, BOE, EUR-Lex, RIS, the Bundesgerichtshof, the European Court of Human Rights, and hundreds more — and exposes them through a focused tool surface: hybrid semantic + keyword search, citation resolution (ECLI, CELEX, case numbers, article references with 95% accuracy across 184 sources), full-text retrieval, and discovery tools that tell the assistant what we have for a jurisdiction before it queries.

Free tier covers 20 searches/day for punctual research needs; paid plans scale to 100,000/month. Used by lawyers, paralegals, and legal-tech builders worldwide.
