Doctrine was founded in June 2016 in Paris by Nicolas Bustamante, Antoine Dusséaux, and River Champeimont. The platform has grown to serve over 27,000 legal professionals daily across France, Italy, Germany, and Spain, including solo practitioners, top-tier international law firms, multinational corporations, French ministries, local authorities, and universities. In April 2026, RELX Group (owner of LexisNexis) announced a put option agreement to acquire Doctrine, recognizing it as the leading legal AI platform for Continental European civil law jurisdictions.
Doctrine aggregates and indexes the full corpus of French and European case law, legislation, regulatory texts, legal doctrine, and secondary sources into a single searchable environment powered by AI and NLP algorithms. Key capabilities include semantic full-text search across millions of decisions, automated legal citation tracking, legislative history mapping, and AI-assisted analysis tools for drafting memos and identifying relevant precedents. The platform's coverage spans civil, commercial, criminal, administrative, and constitutional law across multiple civil law countries.
Doctrine differentiates by combining breadth of coverage across Continental European civil law systems with AI tools purpose-built for the French legal method — including analysis aligned with the structure of French legal reasoning and the citation norms of French courts. This makes it substantially more useful for French-language practitioners than generic AI research tools trained primarily on common law or English-language data.
Best fit: French and Francophone lawyers in private practice, in-house counsel at companies operating in France and Continental Europe, legal academics and students at French universities, and international law firms advising clients on French or EU regulatory matters.
