Themis

Automated exploration and auditing of suspicious public procurement in Chile

themis.lat

Themis is an AI-powered platform that automatically analyzes public tenders from Chile's Mercado Público to detect:

• Regulatory violations - Non-compliance with procurement laws and regulations
• Suspicious patterns - Anomalies in award decisions and bidding behavior
• Procurement irregularities - Red flags in purchasing processes

Themis brings transparency to public spending by making it easy to investigate and audit government contracts.

Themis uses a multi-agent AI system built with LangGraph that can:

1. Fetch tender data from Mercado Público's API
2. Analyze documents including contracts, specifications, and award decisions
3. Detect anomalies using specialized fraud detection agents
4. Generate reports summarizing findings and ranking issues by severity
