Newton: The Expert Witness Agent for Slack, Teams & Email

The Call That Doesn't Get Returned

It's 6:47pm on a Thursday. You're an adjuster staring at a $92,000 demand package for a rear-end collision at 12 mph. The plaintiff claims a C5-C6 disc herniation. You need a biomechanical opinion before tomorrow's mediation, and your reconstructionist's voicemail is full.

So you open Slack. You type: "Newton, here's the crash photo and the MRI report. What's the Delta-V range, and does it support a disc herniation at AIS 3?"

Forty seconds later, you have a Delta-V estimate of 8.2 to 10.6 mph, a crash pulse profile, an AIS injury probability distribution showing less than 4% likelihood of disc herniation at that energy level, and a damage severity score of 31 out of 100. The reply lands in the same Slack thread where your team is already discussing the file.

That's Newton. The expert witness agent that works where you already work.

What Newton Actually Is

Newton is Silent Witness's expert witness agent. It's not a chatbot bolted onto a website. It's a persistent, channel-native agent that lives inside Slack, Microsoft Teams, and email. You talk to it the way you'd talk to a colleague. You upload evidence, ask questions, and get back physics-validated crash reconstruction and biomechanical injury analysis, all within the conversation thread you're already in.

No new login. No separate portal. No context switching.

The analysis underneath is the same Delta-V engine and occupant kinematics model that Silent Witness has validated against NHTSA's crash test database, scoring 96% agreement with IIHS barrier test data. Newton just removes the friction between you and the science. You send photos. You get a report. The report meets Daubert admissibility standards because the methodology is deterministic, not generative opinion.

"The bottleneck was never the analysis. It was getting the evidence to the analyst and the report back to the team. When the agent lives in the channel, the bottleneck disappears."

Why an Agent, Not a Portal

Most claims teams have a familiar workflow problem. Evidence lives in one system. Communication happens in another. Reports get generated in a third. By the time a PDF lands in someone's inbox, the conversation has moved on and the context is gone.

Newton collapses those layers. Here's what that looks like in practice.

A defense attorney drops three crash photos into a Microsoft Teams channel at 8:15am. She tags Newton and asks for a PDOF analysis and occupant kinematics summary for a belted driver, no airbag deployment. By 8:20am, Newton has returned the principal direction of force at 11 o'clock, a g-force profile peaking at 7.3g over 114 milliseconds, and an AIS probability table showing a 67% likelihood of AIS 1 cervical strain and a 12% chance of AIS 2. The attorney copies the output directly into her motion for summary judgment.

Or consider the SIU investigator who forwards a claimant's demand letter and five photos to Newton via email. Newton flags a damage-injury mismatch: the vehicle shows cosmetic bumper deformation consistent with a Delta-V under 6 mph, but the demand alleges lumbar radiculopathy and a $185,000 treatment lien. That mismatch score, quantified as part of Silent Witness's exposure scoring methodology, gives the investigator a documented, physics-backed reason to escalate the file.

No one opened a separate platform. No one waited three weeks for a report.

The Science Doesn't Change. The Access Does.

Newton runs the same validated reconstruction pipeline that produces court-ready reports at $100 each. Delta-V estimation from photo-based structural deformation analysis. Crash pulse modeling calibrated against NHTSA's FMVSS 208 and 214 frontal and side-impact test series. Occupant kinematics computed for the specific restraint conditions in the vehicle, whether that's a three-point belt with a frontal airbag or an unbelted rear passenger.

What changes is how you reach it.

Instead of uploading to a web portal and waiting, you message Newton in the channel where your team already triages claims. The agent understands context. If you ask a follow-up question in the same thread ("What if the occupant was unbelted?"), Newton reruns the kinematics with updated restraint parameters and returns the revised AIS probabilities. No new upload. No new case number.

For firms handling volume, this matters. A regional TPA processing 400 BI claims per month doesn't need 400 separate logins. They need an agent sitting in the claims channel, ready to score the next file the moment it's discussed.

Where This Fits in Your Workflow

Newton isn't replacing your expert witnesses. It's the layer that tells you whether you need one.

On a straightforward rear-end at 9 mph with a $38,000 soft-tissue demand, Newton's Delta-V range and AIS probabilities might be all you need to set reserves, counter the demand, or close the file. On a complex multi-vehicle intersection crash with a $1.2M exposure, Newton gives your retained reconstructionist a head start: initial Delta-V, PDOF, damage severity scoring, and occupant kinematics already computed before the expert's first billable hour.

Either way, the science reaches you faster. And it reaches you where you're already working.

We've seen early users cut their average time-to-first-biomechanical-opinion from 11 days to under 10 minutes. Not because the physics got simpler. Because the delivery channel finally matched the speed of the conversation.

Getting Started

Newton is available now for Slack, Microsoft Teams, and email. Setup takes less than a day. Your team keeps using the tools they already have, and now those tools have a forensic expert sitting inside them.

If you want to see Newton work a real file in your own Slack or Teams workspace, book a demo on silentwitness.ai.

Frequently Asked Questions

Does Newton produce Daubert-admissible reports?

Yes. Newton's analysis uses the same deterministic physics engine validated against NHTSA and IIHS crash test data. The methodology is repeatable, peer-reviewable, and built to meet Federal Rule of Evidence 702 requirements for expert testimony.

Can Newton handle follow-up questions in the same conversation thread?

It can. If you change a variable (restraint status, occupant position, number of occupants), Newton reruns the kinematics and returns updated AIS probabilities within the same thread. No new case submission required.

What does Newton need to run an analysis?

At minimum, three crash photos showing vehicle damage. For fuller biomechanical output, adding occupant details (belted or unbelted, seat position, airbag deployment status) produces more specific injury probability distributions. You can also attach medical records or demand letters for mismatch detection.

How much does a Newton analysis cost?

Each court-ready report is $100. That includes Delta-V estimation, PDOF, crash pulse, g-force profiles, damage severity scoring, occupant kinematics, and AIS injury probability tables.

Which channels does Newton support?

Newton currently operates natively in Slack, Microsoft Teams, and email. The agent responds in the same thread or email chain where you submit evidence, so your team never leaves their primary communication tool.
