A new AI mortgage app is aiming to transform the traditional home-loan process by dramatically reducing the time required for mortgage underwriting. The online lending platform Better has partnered with OpenAI to launch a tool inside ChatGPT that could streamline mortgage approvals for banks, brokers, and financial technology firms.

According to company executives, the application integrates Better’s digital mortgage infrastructure with OpenAI’s advanced artificial intelligence models. By combining these technologies, the platform can automate complex underwriting tasks that historically required days or even weeks of manual work.

Mortgage Processing Gets a Major Upgrade

The new AI mortgage app focuses on one of the most time-consuming stages of home lending: underwriting. This process evaluates a borrower’s financial history, income, credit profile, and property details before a loan is approved.

Vishal Garg, chief executive of Better, said the system allows loan officers to complete underwriting dramatically faster than before. Instead of waiting roughly three weeks for approvals, lenders could finalize decisions in as little as 47 seconds using the automated system.

Executives say the technology could significantly reduce the administrative burden that has long slowed mortgage approvals across the industry.

AI Aims to Transform the Lending Industry

Leaders at OpenAI believe the AI mortgage app represents an important milestone in applying artificial intelligence to financial services. Giancarlo Lionetti, OpenAI’s chief commercial officer, said the partnership could reshape how Americans finance home purchases.

Lionetti noted that many borrowers have experienced lengthy and complicated mortgage processes. By enabling underwriting through AI-powered workflows, the companies aim to make home financing faster, less expensive, and more accessible.

The collaboration highlights the growing role of artificial intelligence in industries traditionally dependent on manual review and paperwork.

A Traditionally Slow Process

For decades, mortgage underwriting has been one of the slowest processes in consumer finance. Loan approvals often require dozens of verification steps involving property appraisals, income documentation, credit checks, and title reviews.

After the 2008 financial crisis, several large banks reduced their involvement in the mortgage market. As a result, non-bank lenders gained a larger share of the industry.

Companies such as Rocket Mortgage and United Wholesale Mortgage became major players in the U.S. mortgage market, which now originates more than $1 trillion in loans each year.

Market Reaction to the Announcement

Financial markets reacted quickly to the launch of the AI mortgage app. Shares of Better rose following the announcement, reflecting investor optimism about the company’s new strategy.

At the same time, shares of several major mortgage lenders moved lower. Stocks for Rocket Mortgage declined during trading, while United Wholesale Mortgage also saw a drop in its share price.

Investors appear to be evaluating how artificial intelligence could disrupt existing mortgage business models.

Technology Could Challenge Industry Leaders

Better executives believe the AI mortgage app could shift competition across the mortgage industry. Instead of focusing solely on direct lending to consumers, the company is repositioning itself as a technology provider for other lenders.

Garg explained that the platform effectively turns Better into a “mortgage-as-a-service” provider. By licensing its technology to banks and brokers, the company hopes to help smaller lenders compete more effectively with large institutions.

Faster processing could also lower operating costs for lenders, potentially reducing fees for borrowers.

AI Automates Complex Financial Checks

The new platform relies on OpenAI’s models combined with Better’s extensive mortgage data. The system can evaluate multiple financial factors simultaneously instead of processing them sequentially.

According to Garg, the AI mortgage app performs parallel checks on several critical underwriting components. These include income verification, property appraisals, credit reports, title documentation, and additional financial metrics.

By analyzing these inputs simultaneously, the system reduces processing time while maintaining accuracy in the approval process.

A New Era for Mortgage Technology

Industry analysts say artificial intelligence could reshape the mortgage sector if these tools prove reliable at scale. Faster approvals could improve customer experiences while reducing costs across the lending ecosystem.

As AI technologies expand into more areas of financial services, traditional workflows may continue to evolve. Companies that successfully integrate automation could gain a significant competitive advantage.

If widely adopted, the AI mortgage app could mark a turning point in how mortgages are evaluated, approved, and delivered to homebuyers.
