Silex

Silex is a Swiss AI-powered legal research platform built on a proprietary legal intelligence infrastructure developed from the ground up, including custom AI models, data ingestion pipelines, and legal reasoning architecture, rather than adapting off-the-shelf large language models for legal use. 

Key features and functions include:

Natural Language Legal Research
Users submit legal questions in natural language; Silex analyzes the context and complexity of the query and returns a documented answer with citations to relevant Swiss legal sources within seconds. The platform is designed to surface sources the user may not have identified through manual research, including sources across cantonal and federal law.

Swiss Legal Source Coverage
Silex indexes more than 800,000 Swiss and international legal sources, including federal and cantonal statutes, case law, legal doctrine, and regulatory materials. Sources are updated daily to reflect legislative changes and new decisions. Legal texts in languages other than French and English are translated by Silex into French and English for access.

Source-Grounded Responses with Active Hallucination Reduction
Every response generated by Silex is grounded in explicit legal sources and includes traceable citations. The platform applies active hallucination reduction techniques designed to minimize the generation of fabricated or unsupported legal references — a known limitation of general-purpose AI tools in legal research contexts.

Contextual Filtering by Canton, Field, and Format
Users can apply filters to refine research results by canton, area of law, document format, and additional source types including administrative circulars and web content. These filters allow practitioners to narrow results to the jurisdiction and legal domain most relevant to a given matter.

Folder and Session Organization
Silex provides a sidebar folder structure enabling users to organize research queries and sessions by matter, client, or topic. This allows legal professionals to categorize and retrieve prior research efficiently within their workflow.

Private Knowledge Integration
The platform supports the integration of a firm's or organization's internal documents alongside public legal sources, through secure and isolated data silos. This enables AI-assisted research across both public law and private client documents without commingling data or compromising professional secrecy obligations.
