Legal AI

AiLexLux

Grounded legal AI for Luxembourg and beyond.

AiLexLux is built around a simple principle: the model should reason, while the legal layer retrieves authoritative law, case law, versions, citations, and source links.

Where it fits

AiLexLux combines top language models with authoritative legal retrieval, version awareness, citation handling, and grounded legal drafting workflows.

  • Lawyers who need inspectable AI-assisted drafting
  • Legal departments that need traceability and deployment control
  • Matters that cross Luxembourg, EU, or other legal source families

Business outcome

Legal AI that stays anchored to source authority instead of plausible unsupported output.

A legal layer around the best models

AiLexLux does not try to replace frontier language models with a small legal chatbot. It gives strong models the retrieval, versioning, citation, and provenance layer legal work actually requires.

  • Top-tier models for reasoning and drafting
  • Authoritative retrieval for law and case law
  • Direct links back to source authority

Modular by design

Legal work crosses source families and jurisdictions. AiLexLux is designed around modules that can support deep retrieval inside one source and unified retrieval across subscribed sources.

  • Luxembourg law with Legilux as authority
  • Luxembourg case law repositories
  • EU law with EUR-Lex
  • French law with Legifrance

Deployment control

Legal teams should not have to choose between capability and control. AiLexLux can support cloud, local, and hybrid model paths depending on confidentiality and policy requirements.

  • Cloud models for maximum performance
  • Local models for controlled environments
  • Hybrid setups for matter-specific requirements
