Questions, answered
How does Silent Witness compare to traditional expert witnesses?
Silent Witness accelerates the technical foundation: Delta-V, crash pulse, occupant kinematics, and injury probability. Expert review can still be used when testimony, jurisdiction-specific admissibility, or case strategy requires it.
Is Silent Witness analysis admissible in court?
Reports are designed around traceable methodology and documented assumptions. Legal teams should evaluate admissibility with counsel and the appropriate expert for the venue and use case.
What types of evidence can I upload?
Crash photos, repair estimates, police reports, medical records, scene photos, and other structured or unstructured case documents.
How accurate is the Delta-V calculation?
The platform returns a defensible range with confidence scoring, not a false single point estimate. Assumptions and source evidence are documented in the report.
Can I integrate Silent Witness into my existing workflow?
Yes. The SDK and API are designed for legal-tech products, claim systems, intake workflows, and internal case review tools.
What is the pricing model?
The first crash analysis request is free. Standard reports are positioned at $100 per report, with enterprise pricing available for teams and API programs.
