How does Silent Witness compare to traditional expert witnesses?

Court-defensible analysis in seconds, not weeks, at a fraction of expert witness cost. Same scientific methodologies (crash physics, biomechanics, forensic analysis), processed orders of magnitude faster. Backed by peer-reviewed science and 500K+ training datasets.

Is Silent Witness analysis admissible in court?

Admissibility is decided by the court on a case-by-case basis. Our analyses apply the same crash physics and biomechanical methods used by human reconstructionists, with transparent calculations, cited literature, and documented assumptions, giving an attorney the foundation to argue for admission. We don't promise admission in any specific case.

What types of evidence can I upload?

Crash photos, repair estimates, police reports, medical records, witness statements, and vehicle data. Our Vision AI automatically extracts relevant data from all uploads.

How accurate is the Delta-V calculation?

More accurate than traditional reconstruction software, validated against NHTSA and IIHS crash test data. It uses the same momentum and energy-based methodologies as certified human reconstructionists.

Can I integrate Silent Witness into my existing workflow?

Yes. Our SDK and REST API provide programmatic access to all capabilities. We also integrate with major legal practice management and case management platforms.

What is the pricing model?

Individual analyses start at $100/report. Monthly subscriptions and enterprise plans with volume discounts available for carriers and firms.

PI Firm Case Intake Volume Benchmarks: How Top Firms Process 500+ Monthly

A mid-size PI firm in Atlanta signed 312 cases last month but only moved 114 to active status within two weeks. The bottleneck wasn't lead gen. It was the inability to score crash severity fast enough to prioritize which cases deserved attorney attention on day one.

Automotive Product Liability Expert Witness: Why Engineers Miss $3M Defect Cases

A seatback fails in a 42 mph rear-end. Your biomechanical expert says the injuries are consistent with the crash. The defense expert says the occupant wasn't belted. Neither one has the crash pulse data to prove their theory. That gap is where $3M cases go to die.

E-Bike Accident Injury Severity Prediction: Why 20 MPH Crashes Generate $2M Claims

A 22 mph e-bike struck broadside by a sedan turning left. The vehicle damage barely qualifies as moderate. The rider's injuries score AIS 3 to 4 across three body regions. E-bike collision physics break every assumption adjusters and attorneys carry over from car-on-car cases.
