AIG to roll out AIG Assist across Lexington by end of 2025
AIG is expanding its generative-AI underwriting tool, AIG Assist, across the remainder of its wholesale-only Lexington Insurance Company business by the end of 2025, after early results showed faster submission handling and higher submit-to-bind ratios.
The tool, which debuted in late 2024 inside AIG’s North America Financial Lines unit, automates the first pass of underwriting by extracting data from broker submissions, structuring unstructured documents, and surfacing key risk information to underwriters. According to AIG’s Q3 2025 earnings call, the company is now processing 100% of applicable private and nonprofit submissions through AIG Assist, with plans to accelerate rollout across North America, the U.K., and EMEA commercial lines.
AIG leadership positioned the move as a response to escalating submission volumes—Lexington alone has received nearly 200,000 submissions year-to-date—which the company says cannot be addressed simply by adding more staff. The tool is also being piloted on the claims side to speed first-notice-of-loss intake and coverage-letter generation.
AIG attributed the acceleration of AIG Assist to a patent-pending capability called Auto Extract, which uses large language models to structure data from documents, websites, and conversations. The insurer describes the technology as central to its plan to shorten underwriting cycle times and expand capacity without increasing headcount.
Background: What Other Insurers Are Doing With AI
AIG Assist is landing in a market where insurers are racing to embed AI deeper into underwriting, claims, and customer decisioning. Recent moves include:
Aviva
Aviva is deploying an AI summarization tool that condenses lengthy GP medical reports into short underwriting-ready summaries. The goal: reduce decision time in life and health underwriting while maintaining accuracy and auditability.
CNA Insurance Canada × mea Platform
CNA Insurance Canada is expanding its partnership with mea Platform after a successful pilot. mea’s AI engine helps the insurer clean and structure incoming data, speed underwriting workflows, and support a broader data-first operating model across commercial lines.
Chubb — Chubb Studio Optimization Engine
Chubb introduced an AI optimization engine inside Chubb Studio, its embedded-insurance platform. The engine analyzes partner and customer data to place personalized insurance offers at checkout, designed to improve engagement and conversion for banks, airlines, and fintech partners using the platform.
Zurich — ZuriFault
Zurich developed ZuriFault, an agentic AI system that assists motor liability decisions. The tool analyzes claims data and documentation, helping adjusters reach faster and more consistent outcomes while reducing manual review.
Vitality × Google
Vitality and Google launched Vitality AI, a global platform powered by Google Cloud’s Vertex and Gemini models. The platform uses health, activity, and lifestyle data to deliver personalized behavior recommendations and real-time health insights to members across markets.
