Paragraf Lex - Serbia's primary legal information platform
Lex AI is our own product. We built it, and it operates natively inside Paragraf Lex - the de facto reference platform for Serbian legal professionals - through a commercial partnership. It compresses the path from a serious legal question to a sourced, verifiable answer.

The challenge
Serbian legal language is technically dense and morphologically rich. Articles cross-reference each other in ways that don't survive naive search. Hallucinating in a legal product is worse than no answer.
Our approach
Built around Paragraf Lex's editorial discipline. Source-anchored reasoning with explicit citations into the underlying material - the lawyer verifies in a click. We do not publish system internals.
Why it is non-trivial
Surviving production with a legal audience required deep domain modelling, sustained editorial partnership, and an evaluation posture that treats accuracy and provenance as primary metrics, not secondary ones.
Editorial partnership
Built around Paragraf Lex's editorial discipline. Their editors are co-authors of the product - their domain authority shapes what the system says, and what it refuses to say.
- CLIENT ENGAGEMENTS
Two engagements for the Art Loss Register.
Both are in phased rollout and going live in 2026.
The Classic Car Register
A vehicle-aware retrieval engagement that links visual evidence to provenance claims across centuries and auction houses.
- PRACTICE AREAS
Six practice areas behind these solutions.
Methodology that applies beyond the engagements above - to regulated industries, financial services, the public sector, and industrial environments.
01
Reasoning agents
Source-anchored answers in domains where correctness is verifiable.
02
Document intelligence
Layout-aware understanding for complex archives, contracts, claims, reports.
03
Retrieval systems
Hybrid lexical-semantic search with domain-tuned ranking; cross-modal where vision matters.
04
Vision & multimodal
Visual evidence as first-class input - provenance, inspection, archival material.
05
Agentic AI
Action-taking systems with bounded action surfaces and audit trails.
06
Predictive ML
Forecasting, anomaly detection, decision-aware classification and ranking.
