Forensic Evidence Verification System
A cutting-edge forensic analysis tool powered by Gemini 3 Pro that detects contradictions, reconstructs timelines, and validates evidence authenticity across multimodal sources.
Verity leverages Gemini 3 Pro's advanced reasoning capabilities to analyze complex forensic evidence, detect deception, and reconstruct event timelines with unprecedented accuracy. Built for legal professionals, investigators, and compliance teams.
- Advanced Reasoning - Gemini 3 Pro's thinking mode provides transparent, step-by-step analysis
- Multimodal Analysis - Process documents, images, transcripts, and financial records simultaneously
- Contradiction Detection - Automatically identify conflicting claims across evidence sources
- Timeline Reconstruction - Build precise chronologies from metadata and content analysis
- Visual Intelligence - Interactive contradiction maps and animated timelines
- Evidence Integrity - Detect tampering through metadata analysis and cross-referencing
Verity uses a Golden Path demo system designed for the Gemini 3 hackathon:
Pre-validated Gemini 3 Pro analysis from AI Studio showcasing:
- Insider Trading Case - CEO stock sales + acquisition timeline analysis
- Real Gemini 3 Pro thinking steps and reasoning
- High-complexity forensic scenario with MNPI (Material Non-Public Information)
Why Sample Mode?
- Gemini 3 Pro preview has strict rate limits
- Ensures judges can experience full capabilities without quota errors
- Demonstrates authentic Gemini 3 output validated via AI Studio
Live analysis with graceful fallback:
- Attempts Gemini 3 Pro (if quota available)
- Falls back to Gemini 2.0 Flash if needed
- Transparent status indicators show which model is active
- Frontend: React 18 + Vite
- AI: Gemini 3 Pro via
@google/generative-aiSDK - Visualization: D3.js for contradiction maps
- Animation: Framer Motion
- Styling: Tailwind CSS + Custom gradients

Gemini 3 Pro's step-by-step thinking mode shows transparent analysis:
- Forensic evidence analysis
- Temporal data refinement
- Contradiction evaluation
- Timeline construction
Visual representation of conflicting claims with credibility scoring:
- Red nodes = Low credibility (self-reported claims)
- Green nodes = High credibility (documentary evidence)
- Dashed lines = Contradiction links
Chronological event sequence with confidence scores and source attribution.
Comprehensive summary and verdict generation.
