Uwindaji KitMaintained

Uwindaji can automatically find facts about intelligence targets, keep them tamper-proof, maintain provenance, monitor developments.

You specify a person or organization, you get a report from multiple distributed tools that work together. Every domain, email, phone number and address triggers “specialist” services (non-LLM), which enrich them and share findings between themselves. You can analyze it manually or use it with agents as MCP/CLI (LLMs love to play spies).

Currently this system monitors and prevents sanctions compliance violations.
