Mortgage Automation Technologies Unveils An Open, Admin-Controlled AI Suite For Mortgage Lending

Mortgage Automation Technologies, Inc. (MAT), creator of The BIG Point of Sale, launched BIG AI — an artificial intelligence product suite that brings enterprise-grade, Amazon Bedrock-powered business intelligence directly into the hands of mortgage professionals.

BIG AI enables loan officers, operations teams, executives to interact with their loan data through a natural language interface — asking questions in plain English and receiving instant answers in the form of charts, tables, reports, and fully generated documents. No SQL. No spreadsheets. No waiting on analysts.

However, BIG AI isn’t just another chatbot bolted onto a mortgage platform. MAT has built a fully transparent, admin-controlled AI architecture where lenders own the intelligence layer — not the vendor.

“We looked at the market and saw an entire industry being asked to hand over the keys to their AI with zero visibility into what’s happening underneath,” said Matthew Van Fossen, CEO Mortgage Automation Technologies. “Lenders are regulated entities. They can’t afford a black box making decisions about what their loan officers see, what data gets exposed, or how the AI responds to sensitive topics. BIG AI breaks that model open.”

With BIG AI, mortgage lenders get full, transparent control over every layer of AI behavior — from the foundation model powering the intelligence, to the exact prompts their users see, to the compliance guardrails that keep everything within regulatory boundaries.

The BIG AI suite launches with two flagship products, both built natively inside The BIG Point of Sale and powered by Amazon Bedrock:

Mortgage GPT — The AI interface for loan officers, operations, executives, and consumers. Mortgage GPT delivers a ChatGPT-like experience purpose-built for mortgage: natural language pipeline queries, automated report generation, client proposal creation, amortization schedules, performance analytics, voice integration, and file-based analysis. Users interact through clickable prompt cards, conversational chat — and every response is powered by real-time data from the lender’s own loan origination system (LOS) instance via The BIG Point of Sale API.

Mortgage GPT supports role-based access across every position in a mortgage organization. Loan officers see their pipeline. Branch managers see their team. Executives see the entire company. The data is always relevant, always permissioned, and always compliant.

Tsunami AI Admin — A no-code AI administration and compliance portal for mortgage lenders. Tsunami AI Admin gives system administrators and compliance officers a complete control panel for every aspect of AI behavior — without writing a single line of code or submitting a single developer request.

Through Tsunami AI Admin, lenders can create and manage content safety guardrails across categories including data privacy, legal compliance, HR liability, and custom company-specific rules. They can build and publish no-code prompt templates with dynamic Encompass field variables and assign them to specific user roles. They can choose their Amazon Bedrock foundation model, tune temperature and token parameters and monitor per-client knowledge base instances. They can control exactly which LOS fields the AI is permitted to access, with automatic personal identifiable information (PII) detection and real-time Regulation C compliance scoring that updates as configurations change. And every single administrative action is logged in a timestamped audit trail.

“Our tagline for Tsunami AI Admin is ‘Break Open the Black Box,’” Matt Van Fossen continued. “We don’t just give lenders AI. We give them control of AI. That’s the disruption. Every other vendor in this space asks you to trust their prompts, trust their guardrails, trust their compliance layer. We say: here are the keys. You decide.”

BIG AI is not a standalone product. It is built natively inside The BIG Point of Sale — MAT’s flagship mortgage platform that already connects borrowers, loan officers, processors, underwriters, and executives in a single system with real-time LOS integration. This means BIG AI has direct, secure API access to live loan data from day one. There is no separate data migration, no third-party connector, and no synchronization delay. The intelligence layer sits on top of the operational layer, which is exactly where it belongs.
