Investigation Evidence Mapper
Map evidence, spot conflicts, build legally defensible investigation narratives
What You Can Do
You can organize complex investigations into structured evidence maps that connect sources, dates, and claims. Claude helps you identify conflicts between accounts, spot gaps in your reporting, and build narrative outlines where every claim traces directly back to verified sources. This turns raw research chaos into a defensible investigation dossier ready for publication.
Features
Convert raw research into structured databases with claims, sources, dates, verification status, and confidence levels
Automatically flag contradictions, inconsistencies, and gaps between source accounts that need follow-up reporting
Visualize connections between people, organizations, money flows, and events to spot patterns
Build chronological narratives that align with your evidence and identify impossible sequences or missing context
Construct story outlines where every claim links to specific sources, creating traceable chains for legal review
Identify what you're still missing, which sources need follow-up, and which claims need additional verification
Decode decision chains, chain of command, and responsibility in complex institutions
Example Output
Evidence Map Output:
- Claim: "Executive X approved the decision" | Source: Internal memo dated March 15 | Status: Verified | Confidence: High
- Claim: "No knowledge of the issue" (from same executive) | Source: Interview transcript | Status: Conflicts with memo | Follow-up: Needed
Conflict Report:
- Source A (Company lawyer): "Standard procedure, no violations"
- Source B (Whistleblower): "Deliberate bypass of safety checks"
- Source C (Email chain): "Skip the normal sign-off process"
- Recommendation: Interview Source A again with email evidence
Narrative Validation:
- Your story claims: Timeline of events A → B → C
- Evidence check: A confirmed (memo), B partially supported (2 of 3 sources), C contradicted by one source
- Risk level: Medium — needs additional reporting before publication
