Global identity and business verification platform for KYC, KYB, and AML compliance.

The world's most comprehensive legal research platform powered by the Vincent AI legal assistant.

JustisOne, now fully integrated into the vLex ecosystem as vLex Justis, represents the pinnacle of legal research technology in 2026. The platform leverages a sophisticated knowledge graph that connects over 100 million legal documents across 100+ jurisdictions, including the UK, Ireland, Canada, and the Caribbean. Its technical architecture is built around the 'Justis Citator,' which provides a granular view of how cases have been treated over time—distinguishing between applied, followed, and overruled authorities. In 2026, the platform's core differentiator is Vincent AI, a generative AI assistant that uses Retrieval-Augmented Generation (RAG) to provide verified answers to legal queries directly from the vLex database. This ensures that the AI's output is grounded in verifiable case law and statutes rather than hallucinations. The system also features advanced data visualization tools like the Precedent Map, which allows practitioners to identify influential cases through node-based relationship modeling. Designed for top-tier law firms and academic institutions, JustisOne provides high-fidelity legal intelligence that bridges the gap between traditional indexing and modern predictive analytics.
