Large Language Models for InsurTech
Quick Definition
A neural network trained on massive text corpora that can generate, understand, and transform natural language for tasks like summarization, classification, and conversation.
Full glossary entry →Insurance is fundamentally a text-processing business: policies, claims, medical records, legal correspondence, and adjuster notes are all unstructured documents that drive core workflows. LLMs can read, classify, extract, and act on this text at a fraction of the cost of manual processing, dramatically compressing claims cycle times and enabling new instant-quote products. They also power the conversational interfaces that help policyholders understand complex coverage without agent assistance.
How InsurTech Uses Large Language Models
Automated Claims First Notice of Loss
Process FNOL submissions in natural language—whether phone transcript, email, or app submission—extracting structured claim data and triggering the right adjuster workflow automatically.
Policy Document Comparison and Explanation
Let customers ask questions about their policy in plain language and get accurate, grounded answers that cite specific policy sections, reducing agent call volume.
Fraud Narrative Analysis
Identify linguistic patterns in claims narratives that correlate with fraud, flagging suspicious claims for specialist review before payment.
