How AI Accelerates Claim Decision Support in Catastrophe (CAT) Events — Property & Homeowners, Commercial Auto, and Specialty Lines | Catastrophe Adjuster

When a major hurricane, wildfire, derecho, or flood hits, a Catastrophe Adjuster’s world changes overnight. Claim volumes skyrocket, documentation multiplies, and decisions must be made quickly and defensibly. Files include property assessments, loss statements, inspection photos, damage appraisals, FNOL forms, ISO ClaimSearch reports, contractor estimates, and more—often totaling thousands of pages per claim. In these surge events, manual review becomes the bottleneck. This is exactly where Doc Chat by Nomad Data transforms the CAT playbook by turning days of reading into minutes of decision support.

Doc Chat is a suite of purpose-built, AI-powered agents designed for insurance. It ingests entire claim files at scale, understands coverage language and exclusions, reads photos and attachments, and delivers instant, page-linked answers to questions like, “List all roofs with prior hail damage,” or, “Map all damaged vehicles by VIN and location.” For Property & Homeowners, Commercial Auto, and Specialty Lines & Marine, Nomad Data’s Doc Chat for Insurance helps Catastrophe Adjusters automate surge event documentation review, speed triage, cut loss adjustment expense, and elevate accuracy when it matters most.

The CAT Adjuster’s Reality Across Property & Homeowners, Commercial Auto, and Specialty Lines & Marine

Catastrophe claims are different from normal caseloads. A single storm creates highly variable damage patterns across homes, fleets, cargo, and marine assets—each governed by different policy forms and endorsements. A Catastrophe Adjuster must read wide-ranging document types, reconcile conflicting statements, and correlate images, locations, and timelines under severe time pressure.

In Property & Homeowners, adjusters are expected to review property assessments, damage appraisals, inspection photos and videos (including drone imagery), contractor bids, roof diagrams, siding and window counts, ALE receipts, and proof-of-loss statements—while cross-checking policy endorsements, wind/hail deductibles, ordinance or law provisions, and depreciation rules for ACV vs. RCV. In Commercial Auto, the same storm might generate hundreds of comprehensive claims for hail, flood, or wind-blown debris. Adjusters must validate garage and storage locations against the event footprint, compare tow invoices and repair estimates, review police reports where applicable, and check for pre-existing damage cited in prior appraisals. In Specialty Lines & Marine, CAT events trigger port damage, wet cargo, hull breaches, gear losses, and terminal disruptions. Surveyor reports, bills of lading, charter party contracts, USCG or port authority incident logs, and marine survey photos must be reconciled against coverage triggers, exclusions, and potential subrogation against responsible parties.

Layer on the realities of surge staffing—temporary field adjusters, rotating desk adjusters, and vendors—and process consistency becomes difficult. Critical details hide in the long tail of pages and pixels: an endorsement buried in a policy jacket, a time-stamped EXIF field in an inspection photo, a subtle discrepancy between the loss statement and the damage appraisal, or the same vehicle appearing in two claims. Volume and complexity conspire to slow cycle time and increase leakage just when fast, accurate decisions are essential.

How CAT Documentation Is Handled Manually Today

Even at highly advanced carriers, much of CAT documentation review remains manual. The typical process looks like this:

Intake and triage: FNOL forms, emails, and portal uploads are collected; files are routed to Catastrophe Adjusters based on geography, peril, or capacity. A quick completeness check identifies missing items, but this often requires opening and scanning several PDFs and images. The adjuster sets an initial reserve with incomplete information.

Manual reading and note taking: Adjusters read property assessments, loss statements, and damage appraisals, annotating coverage-relevant passages and building a timeline from correspondence, estimates (e.g., Xactimate PDFs), inspection photos, and vendor reports. For Commercial Auto, they compare appraisals, repair estimates, and photos to policy deductibles and exclusions, and reconcile VINs against fleet schedules. For Specialty Lines & Marine, they reconcile surveyor findings with bills of lading, manifests, and charter contracts to determine liability and salvage implications.

Cross-checks and reconciliation: Adjusters flip between policy forms, endorsements, and claim documentation to validate causes of loss and ensure damages align with coverage triggers. They search prior claims via ISO reports, check for potential subrogation, and review weather data or GIS overlays to confirm event parameters. Image validation, if performed, is often manual—opening each photo, checking timestamps, attempting to confirm geolocation, and spotting duplicates by eye.

Summary and communication: Adjusters compile summaries, prepare coverage positions, and draft requests for information (RFIs). They coordinate with contractors, independent adjusters, vendors, and policyholders, often repeating work when new documents arrive or when litigation counsel requests itemized evidence with page or photo references.

This manual approach stresses even the best teams. Cycle times expand, reserves remain volatile, and errors creep in when adjusters must skim thousands of pages in a single shift. The outcome is predictable: delayed settlements, higher LAE, and inconsistent results across desks and vendors—especially in large CAT events.

Automate Surge Event Documentation Review with Doc Chat

Doc Chat by Nomad Data changes the entire tempo of CAT claims. The system ingests entire claim files—including property assessments, loss statements, inspection photos, damage appraisals, FNOL forms, ISO claim reports, repair estimates, police reports, and correspondence—and delivers instant, page-linked answers. It’s designed to automate surge event documentation review with consistency and speed, so Catastrophe Adjusters can focus on determinations, not document hunting.

Doc Chat provides:

Massive ingestion at CAT scale: Upload claim files of any size—hundreds or thousands of pages, dozens or hundreds of images and videos—and begin asking questions immediately. Nomad Data has publicly demonstrated the ability to process approximately 250,000 pages per minute, making it feasible to handle peak CAT volumes without added headcount.
Document understanding across formats: Policies, endorsements, estimates, invoices, ACORD forms, proof-of-loss statements, marine survey reports, bills of lading, and correspondence are read and cross-referenced. The system normalizes inconsistent layouts and terminology so the adjuster gets a unified view.
Image intelligence: Extracts EXIF timestamps and GPS coordinates where available, detects duplicates, clusters similar images, and ties each photo to a location and line item. Ask, “Which inspection photos show roof decking?” or “Identify all vehicles with floodwater lines above sill height,” and get answers with evidence links.
Coverage alignment: Surfaces exclusions, sublimits, special deductibles, warranty provisions, and notice requirements hidden in policy forms and endorsements. The adjuster can ask targeted questions like, “List all endorsements referencing wind-driven rain,” or “Does this hull policy exclude named storms at anchor?”
Real-time Q&A: Type, “Summarize all damage appraisals across the file,” or, “Compare the contractor bid to the Xactimate estimate by trade,” and receive structured answers, with citations to specific pages and images for auditability.
Playbook ‘presets’: Summaries and outputs are tailored to the carrier’s CAT playbooks—e.g., Property & Homeowners roof summaries, Commercial Auto flood submersion checklists, or Marine wet cargo condition checklists—so every adjuster produces consistent work product.

This is not just faster reading. It is a new operating model where the adjuster’s first step is insight, not search.

AI to Process CAT Claim Files at Scale

During surge events, “AI to process CAT claim files” moves from a concept to a necessity. With Doc Chat, Catastrophe Adjusters can ingest an entire claim—the policy jacket, multiple estimates, emails, drone photos, marine surveys, fleet schedules—and immediately ask, “What’s missing for coverage determination?” or “Create a damage-by-location table with photo references.” The system responds in seconds, letting the adjuster move directly to analysis, reserves, and communications.

Great American Insurance Group shared a real-world view of this speed-up: large files that took days to review were reduced to moments, with page-level citations for verification. See their experience in our article, Reimagining Insurance Claims Management: GAIG Accelerates Complex Claims with AI. The same dynamic applies in CAT—when volume spikes, Doc Chat keeps cycle time low and quality high.

Best Tools for Handling High-Volume CAT Claims

Teams often search for the best tools for handling high-volume CAT claims. Doc Chat stands out because it was built for insurance documents and the messy realities of surge events. It goes beyond summarization to surface exclusions, reconcile inconsistent data, read images, and provide page-linked answers.

Line-of-Business Workflows: What Changes for the Catastrophe Adjuster

Property & Homeowners

Core documents: Property assessments, damage appraisals, inspection photos and videos, roof diagrams, loss statements, proof-of-loss forms, contractor bids, Xactimate estimates, invoices, ALE receipts, policy jackets and endorsements, prior loss run reports, ISO ClaimSearch results, and correspondence.

What Doc Chat does: Automatically builds a damage inventory by structure and trade (roof, siding, windows, mechanicals), references photos to line items, highlights potential pre-existing damage, and calls out coverage-limiting language (e.g., special wind/hail deductibles, cosmetic damage exclusions, matching limitations, ordinance or law triggers). It can compare contractor bids to estimates, identify discrepancies by trade, and flag missing documentation (e.g., missing roof core samples, incomplete attic photos, unverified contractor credentials). Ask, “Summarize water entry points indicated in inspection notes and photos,” and receive a linked list of evidence. Ask, “Compute preliminary ACV vs RCV exposure for covered items,” and get a structured breakdown with policy references.

Commercial Auto

Core documents: Appraisals, repair estimates, tow invoices, storage bills, fleet schedules, police reports, inspection photos, driver statements, telematics reports, policy declarations and endorsements, proof-of-loss statements, and prior claim histories.

What Doc Chat does: Reconciles VINs against schedules, ties images to unit numbers, detects duplicate damage across claims, and highlights policy provisions that matter in CAT (e.g., flood submersion, comprehensive vs. collision, custom equipment endorsements). It can triangulate storage location timestamps with the event footprint, flag potential fraud signals (e.g., inconsistent waterline heights across photos), and produce a ready-to-send RFI list. Ask, “List all vehicles with airbag deployment mentioned anywhere,” or, “Compare repair estimate labor rates to market benchmarks referenced in the file,” and receive verified answers with citations.

Specialty Lines & Marine

Core documents: Marine surveyor reports, bills of lading, manifests, mate’s receipts, charter party contracts, USCG or port authority reports, terminal logs, photos of hulls and cargo, salvage invoices, general average notices, policy forms and endorsements, and correspondences between carriers, shippers, and brokers.

What Doc Chat does: Cross-links survey findings to policy triggers, evaluates exclusions like “inherent vice” or “delay,” and keeps a chain-of-custody view of cargo condition and handoffs. For hull damage, it correlates photos to surveyed locations; for wet cargo, it tallies damaged SKUs versus manifests and flags potential subrogation targets (e.g., terminal negligence). Ask, “Extract all clauses defining perils of the sea and any storm-related carveouts,” or, “Create a table of damaged cargo lots with corresponding photos and bills of lading,” and get a composed, auditable package in seconds.

From Manual to Autonomous: How Doc Chat Executes Each Step

Here’s a side-by-side view of the CAT workflow shift:

Intake and completeness: Instead of eyeballing PDFs and photos, Doc Chat classifies every file, detects missing standard components (e.g., FNOL, policy jacket, site photos, appraisals), and suggests a targeted RFI list on day one.
Coverage linking: Rather than paging through endorsements, ask Doc Chat to list all sections that affect the stated damage categories. It compiles a coverage map with citations and highlights potential pitfalls like notice requirements or sublimits.
Evidence construction: The AI clusters photos, extracts geolocation and timestamps where available, tags visible damage, and builds a traceable, photo-cited evidence package per location, vehicle, or cargo lot.
Summaries and decisions: Doc Chat generates playbook-specific summaries—Property roof loss synopsis, Commercial Auto flood exposure overview, Marine wet cargo validation—ready to paste into claim notes or share with supervisors and counsel.
Continuous Q&A: When new documents arrive, the AI updates the completeness view and incorporates the new evidence into all downstream summaries automatically.

Fraud Detection and Quality Control During CAT Surges

High-volume events create more opportunities for honest mistakes and opportunistic fraud. Doc Chat systematizes fraud vigilance so Catastrophe Adjusters do not rely solely on memory or manual scans.

Doc Chat can:

Spot duplicates and anomalies in images: Identify repeated photos across different claims, detect inconsistent EXIF timestamps, and flag suspiciously similar damage descriptions.
Cross-reference prior losses: Surface prior damage from earlier appraisals or ISO reports that may reappear in a new CAT claim.
Align with event parameters: Compare address and time-of-loss details to weather footprints and flood maps to validate plausibility.
Guide next steps: Recommend verification actions—e.g., request additional elevation photos, ask for dry-out documentation, or confirm actual storage lot location for Commercial Auto units.

These capabilities mirror what top adjusters do at their best and make it routine for every file. For an in-depth look at how AI codifies expert rules and inference (not just extraction), read Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs.

Business Impact in CAT: Time, Cost, Accuracy, and Policyholder Experience

CAT events magnify every inefficiency. Doc Chat turns the surge into a manageable, auditable flow—and the gains compound fast:

Time savings: Clients routinely see multi-hour manual reviews shrink to minutes. Large, complex files that once required multiple shifts can be summarized in under a minute with page-level citations, as discussed in our article Reimagining Claims Processing Through AI Transformation. This speed keeps reserves current, empowers earlier coverage positions, and reduces backlogs.

Cost reduction: By removing manual touchpoints, carriers reduce overtime and vendor reliance, lowering LAE without sacrificing quality. One of the biggest hidden cost drivers in CAT—attrition and burnout from rote review—drops when adjusters spend time on high-value investigation instead of PDF spelunking. For broader context on ROI and automation of document-driven work, see AI’s Untapped Goldmine: Automating Data Entry.

Accuracy and consistency: Adjusters are human; fatigue is real. AI reviews page 1 and page 1,500 with equal attention, ensuring no endorsement, sublimit, or damage item is overlooked. Standardized playbook outputs ensure CAT-wide consistency across Property & Homeowners, Commercial Auto, and Specialty Lines & Marine.

Policyholder experience: Faster, clearer communication reduces anxiety. Doc Chat helps Catastrophe Adjusters answer specific questions—“What’s covered and why?”—with page-linked evidence that maintains trust in stressful moments.

How Doc Chat Automates the Details Catastrophe Adjusters Care About

Doc Chat is not general-purpose summarization. It’s tuned for insurance evidence and decisioning. During CAT events, that means:

End-to-end file mastery: From FNOL to final proof-of-loss, Doc Chat reads FNOL forms, policy jackets, endorsements, statements of loss, inspection photos, drone footage, police reports, ISO claim reports, and contractor bids. It indexes everything for real-time Q&A with citations.

Visual proof and geovalidation: Photo EXIF data is captured when present; time and place can be cross-checked against known event timelines and footprints. The AI can group exterior photos by elevation (front, rear, left, right) and map images to line items for a ready-to-present evidence set.

Coverage nuance: The system surfaces tricky clauses—matching limitations, anti-concurrent causation, wind vs. flood carveouts, marine perils and exclusions—and connects them to facts in the file, eliminating blind spots that often lead to leakage or disputes.

Triage and RFIs: Automatically identifies missing documents, contradictory statements, or items that require expert inspection (e.g., structural engineering for uplift; ECM pull for submerged vehicles; laboratory inspection for contaminated cargo). It drafts RFIs aligned to your CAT templates.

Subrogation and recovery: Highlights potential third-party responsibility (e.g., contractor negligence, terminal failure, defective parts) and builds a citation-backed packet SIU or subrogation counsel can use immediately.

What “Faster” Really Means in a CAT

Speed is not just a number—it’s the difference between a calm backlog and a runaway one. When Doc Chat turns a three-hour read into a 90-second summary with citations, several things happen at once:

Reserves stabilize earlier: Early, accurate summaries reduce swings in first- and second-week reserve adjustments.
Quality doesn’t slip: Under volume pressure, manual quality often drops. Doc Chat prevents shortcuts by making thorough review the fastest path.
Litigation risk drops: Clear, cited rationales reduce misunderstandings and disputes. If litigation occurs, the file already contains an auditable evidence chain.
Leadership visibility improves: Aggregated insights across thousands of CAT claims—damages by peril, average time-to-coverage position, most frequent missing documents—feed daily command center dashboards.

Addressing Common Questions from Catastrophe Adjusters

Will Doc Chat replace adjusters? No. Doc Chat replaces the reading and re-reading; adjusters keep judgment and negotiation. Think of it as a highly capable junior who never tires and cites every answer.

Can it work with our claims system? Yes. Teams often start with drag-and-drop in the browser and move to API integration for pushing summaries, structured data, and RFIs into the claims platform. Typical initial implementation: 1–2 weeks.

Does it hallucinate? In document-grounded tasks (find, extract, cross-reference), large language models perform reliably—especially with page-level citations. The system is designed to point back to the source page or photo so every answer is verifiable.

How does it handle inconsistent documents? That’s the point. Doc Chat is built for real-world variability. It maps different document layouts and linguistic variations to the same concepts and fields. For how Nomad Data tackles inference across messy documents, see Beyond Extraction.

Operationalizing CAT Excellence: From First Notice to Final Proof of Loss

Here’s how a modern CAT operation looks with Doc Chat in the loop:

Day 0–1: FNOL and policy packets are ingested; Doc Chat runs completeness checks and creates preliminary summaries. Adjusters set informed reserves and send RFIs immediately.

Day 2–5: Field inspections, IA reports, and contractor estimates flow in. Doc Chat updates summaries, reconciles images to line items, and highlights conflicts (e.g., cause-of-loss discrepancy between field notes and contractor narrative).

Day 5–10: Coverage positions are drafted with citations; subrogation opportunities are flagged; Commercial Auto flood exposures are confirmed or ruled out; Marine cargo losses are itemized against bills of lading with photo support.

Day 10+: Ongoing updates are automatic, eliminating time-consuming re-reads. If counsel or reinsurers require evidence, packages are generated directly from the system’s linked answers.

Why Now: The Strategic Case for Doc Chat in CAT

CAT frequency and severity are rising. Documentation volume is increasing. Policy language grows more complex each filing season. The gap between manual capacity and surge reality widens every year. Waiting for the next event to plan a transformation invites avoidable backlog, leakage, and attrition.

Doc Chat is built to close that gap—quickly. It installs fast, adapts to your playbooks, and scales with your volume. And because every answer points to a page or photo, quality assurance and audits become easier, not harder, at CAT scale.
