How we use AI
AI helps our insurance team work faster. Our specialists still own every call.
For Errors & Omissions (E&O) Insurance filings, AI helps our team find the right starting point quickly and reuse data you have already given us, so the work moves without extra effort from you. A licensed Cornerstone specialist reviews everything before it leaves our hands. Your information stays on our infrastructure, not in a public LLM.
On Our Infrastructure
Our models run on Cornerstone servers, not public chatbots. Your business information is not sent to a third-party LLM or used to train anyone else's product.
An Assistant, Not an Operator
AI helps our insurance team start their research in the right place and surface the resources to look at. Specialists vet what comes back and make the call.
Less Duplicate Work for You
Atlas figures out what data each form needs, then reuses what you have already given us so the same question does not come around twice. That is how approvals come faster.
