Investigative Evidence Mapper
Build defensible evidence chains with integrated source verification
What You Can Do
Organize investigative sources into structured evidence chains, verify claims against primary documentation, and map connections between people, organizations, and events. You'll create visual relationship networks, track source credibility, and generate fact-check summaries that withstand scrutiny—all while maintaining an audit trail of your research process.
Features
Build linked timelines of events, claims, and supporting sources with automated chain-of-custody tracking to ensure each conclusion is traceable to verified evidence
Evaluate source credibility using standardized criteria (primary vs. secondary, institutional affiliation, historical accuracy). Assign confidence scores to each claim based on supporting evidence quality
Visualize relationships between people, organizations, and entities mentioned across multiple documents, highlighting patterns and revealing hidden connections
Cross-validate claims against multiple sources, identify contradictions, and flag unverified assertions that need additional investigation
Automatically document your research process—who said what, where it came from, when it was found—creating defensible records suitable for editorial review and fact-checking
Generate publication-ready evidence summaries organized by claim, with supporting sources ranked by credibility and confidence level
Identify potential logical fallacies, circular reasoning, and unsupported leaps in evidence chains before publication
Example Output
Evidence Chain Example:
Claim: Company X received undisclosed foreign funding
✓ Primary Source: SEC filing (2024-03-15) lists subsidiary registration in Delaware ✓ Secondary Source: News article citing company spokesman (2024-03-10) ✓ Supporting Document: Bank records showing wire transfer from offshore account (2024-02-28) ✓ Contradiction Flagged: Company statement denies foreign ties (CEO interview 2024-04-01)
Confidence: 87% — Primary sources support claim; CEO statement contradicts; recommend follow-up interviews
Connection Map Example:
Board Member A → Sits on Board of Company X & Nonprofit Y Board Member A → Married to Consultant B Consultant B → Received $500K contract from Company X (2023) Nonprofit Y → Received donation from Company X (2023)
Pattern Identified: Potential conflict of interest; recommend disclosure verification
