Give facts structure.
Enter source-labeled statements and keep their wording visible for review.
JUSTICE IS JUSTUS / EVIDENCE INTELLIGENCE
Truth has
a pattern.
Meet TATIANA. An evidence-analysis workspace built to surface conflicting statements, preserve context, and give every detail a second look.
SCROLL TO INVESTIGATE ↓
01 / THE MISSION
Every statement deserves scrutiny.
A missed detail can change the understanding of an entire case. TATIANA is a structured approach to evidence review. This interactive lab demonstrates deterministic checks for potentially inconsistent statements. It does not fabricate conclusions or claim that a contradiction proves wrongdoing.
Surface conflicts.
Flag directly opposed assertions concerning the same actor and action.
Export findings.
Download a local JSON report containing each flag and its quoted source statements.
02 / INTERACTIVE EVIDENCE LAB
The evidence speaks.
Look closer.
Paste a JSON object with a statements array, or load the example. Each entry must include source, actor, action, and assertion (true or false). An optional quote preserves the original statement. Analysis runs locally in your browser; this page sends no case data to a server.

No analysis has been run.
Privacy: processing is local to this tab. No upload, account, persistence, or server-side analysis. Do not treat a flag as a legal finding; review source documents and context.
03 / UNDER THE HOOD
Evidence first.
Assertions second.
This standalone interface uses a transparent, deterministic contradiction check. The larger TATIANA bootstrap references Python analysis agents, a Rust contradiction engine, and a Go orchestrator; those backend components are not represented here as connected or deployed. This lab demonstrates the user experience while keeping that engineering boundary explicit.
