Legal Data Hunter
ChatGPT pluginFind laws and cases worldwide
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.

Skills
cross-border-comparison
Compare how a legal question (e.g. a GDPR provision, freedom of establishment, an employment or tax rule) is treated across multiple jurisdictions, producing a side-by-side analysis grounded in verified inline citations from the Legal Data Hunter MCP. Use for comparative or multi-jurisdiction legal questions.
legal-citations
Inline citation discipline for legal analysis with the Legal Data Hunter MCP — never invent or construct a URL, always verify via resolve_reference / get_document / search, cite every legal claim inline (case law, legislation, treaties, doctrine), and append a consolidated Sources section. Use whenever drafting any cited legal analysis or memo.
legal-research
Multi-jurisdictional legal research with the Legal Data Hunter MCP (230+ jurisdictions, 38M+ documents) — statutes, case law, doctrine, comparative and cross-border analysis, regulatory risk, GDPR enforcement across member states, and memo-style answers grounded in verifiable inline citations. Use for legal research, jurisdictional comparisons, cross-border questions, or Legal Data Hunter references.
legal-risk-assessment
Structured legal-risk scoring using a severity × likelihood matrix (1–5 each, score 1–25, GREEN/YELLOW/ORANGE/RED), including per-jurisdiction scoring driven by the highest-risk jurisdiction and triggers for escalating to outside counsel. Use when legal research feeds into a risk assessment or compliance decision across one or more jurisdictions.
multi-issue-memo
Produce a long-form legal memo that decomposes a multi-part question into its sub-issues and resolves each one with its own controlling statute and leading case, fully inline-cited via the Legal Data Hunter MCP (optionally exported to PDF). Use for bar-exam-style or multi-issue advisory questions.
resolve-citation
Turn a loose or messy legal citation (ECLI, CELEX, article number, case/docket number, or informal reference) into the exact verified document and a clickable source URL using the Legal Data Hunter MCP — never a guessed link. Use whenever you need to look up or verify a specific legal reference.
