2asy.ai — Graph RAG in Production

An automated analysis platform that uses the same Graph RAG pipeline built for clients. Every day, it ingests global economic and geopolitical news, extracts causal relationships, and publishes structured analyses with interactive knowledge graphs.

Currently tracking oil, energy, and geopolitical developments — the pipeline is domain-agnostic and extends to any document-heavy vertical.

2asy.ai preview showing knowledge graph and analysis
  • ~2,400 articles ingested daily
  • ~100 articles selected for knowledge graph
  • Causal graph visualization on every edition
  • Runs on Neo4j + LangGraph + Ghost CMS

Live Demos

Three working AI systems, live and interactive. Each demo reflects a real use case (not a prototype).

What Hannune Builds

Hannune builds systems that reduce manual work across data-heavy, search-heavy, and operational workflows.

Workflow automation

Manual processes replaced by automated AI pipelines Large-scale data collection, extraction, and structuring End-to-end document and content workflows

Search and agent systems

Query understanding and retrieval pipelines Extraction, validation, and structured output generation Systems that reduce repetitive document search and review

Production deployment

Docker-based infrastructure for reliable operation REST API integration into client environments Systems running continuously with minimal manual intervention

Identity

Hannune works with enterprise and professional clients who need one accountable technical owner from system design to deployment.

  • Build and deliver AI systems end-to-end
  • Own architecture, implementation, and deployment directly
  • Contract-based work for enterprise and professional clients
  • Solo by design — centralized responsibility and consistent technical judgment

Operating Model

One technical owner from system design to deployment, with no handoff gaps between planning, implementation, and operation.

Fit

Hannune works best where AI can replace real manual workflows and be deployed into actual operations.

When this is a good fit

Teams spending too much time on manual data collection, document search, review, extraction, or repetitive operational workflows. Enterprise or professional clients who need a production-ready system and want one accountable owner from design to deployment.

When this may not be a fit

Projects centered only on research, experimentation, or vague exploration without a clear workflow, operational problem, or deployment goal may be better served elsewhere.

Get In Touch

If your team is spending too much time on manual data, search, or document workflows, Hannune can design and deliver a production-ready AI system.
