Legal and tax intelligence

NEXXOSAT

An institutional-grade intelligence system built to determine not merely whether legal material is relevant, but whether it can be applied to a specific question at a specific point in time.

The problem

Relevance is not applicability.

Conventional retrieval can surface text that appears relevant while missing the legal conditions that determine whether it governs the matter at hand. NEXXOSAT was designed around that distinction.

The system connects legislation, jurisprudence, administrative criteria, doctrine, official authority, and regulatory change within one traceable reasoning architecture.

Technical architecture

What sits behind the demonstration

The public architecture describes the reasoning design and engineering choices without exposing proprietary prompts, internal rules, credentials, or protected source material.

01 / KNOWLEDGE

Legal knowledge graph

Typed entities and relationships represent authorities, rules, concepts, matters, and their dependencies.

02 / TIME

Temporal validity

Legal material is evaluated within its effective period rather than treated as timeless text.

03 / AUTHORITY

Provenance controls

Claims remain connected to official sources and the authority required to support them.

04 / REASONING

Applicability logic

Retrieval is separated from the conditions that determine whether a rule applies.

05 / LANGUAGE

Bilingual operation

The system preserves legal meaning across Spanish and English operating contexts.

06 / CONTROL

Evaluation and evidence

Conclusions are constrained by inspectable evidence, confidence, and explicit reasoning paths.
