The process of securing a home loan, long defined by stacks of paperwork and weeks of agonizing waiting, may be facing a systemic shock. Better has partnered with OpenAI to launch Better’s new ChatGPT app, a conversational credit decision engine designed to condense the mortgage underwriting process from several weeks into under a minute.
The integration combines Better’s proprietary mortgage engine with OpenAI’s advanced models to automate the complex verification steps required for mortgages and home equity loans. The tool is not aimed at consumers directly, but rather at the loan officers working within banks, mortgage brokers, and fintech firms, effectively turning Better into a backend infrastructure provider for the broader housing market.
According to the companies, the app can reduce the underwriting timeline from an average of 21 days to as little as 47 seconds. This acceleration is achieved by running parallel workflows across dozens of critical checkpoints—including income verification, credit reports, title reports, and appraisals—rather than processing them in a linear, manual sequence.

The 47-Second Mortgage Decision
For most homebuyers, underwriting is the “black box” of the financing process, where a lender verifies a borrower’s financial history to determine the risk of the loan. Historically, this has been a labor-intensive manual process. The new AI-driven approach seeks to replace this friction with a “multiple tool call” system that utilizes a large context window to analyze vast amounts of data simultaneously.
“Taking the mortgage underwriting process, which so many of us have experienced personally, from 21 days to as little as 47 seconds and enabling it via ChatGPT is a huge unlock for everyone,” Giancarlo Lionetti, OpenAI’s chief commercial officer, said in a statement.
Lionetti added that the partnership aims to make it “cheaper, faster, and easier for American families to finance a home.” By automating the logic trees that typically require human review, the technology allows lenders to provide near-instant credit decisions, potentially reducing the overhead costs associated with loan processing.
Challenging the “Underwriting Tax”
The launch is a direct shot across the bow of the industry’s dominant non-bank lenders. Better CEO Vishal Garg has characterized the current pricing models of large public lenders as an inefficiency imposed on the public. Garg noted that companies like Rocket Mortgage, United Wholesale Mortgage (UWM), and Pennymac effectively charge a “tax” of approximately 1.5% to underwrite mortgages.
Garg estimates that this cost translates to roughly
| Metric | Traditional Process | Better + OpenAI App |
|---|---|---|
| Average Timeline | ~21 Days | As little as 47 Seconds |
| Workflow Style | Linear/Manual | Parallel/Automated |
| Primary User | Underwriting Staff | Loan Officers/Brokers |
The market reacted swiftly to the announcement. Shares of Better saw an increase of up to 5%, while Rocket Mortgage shares fell as much as 6% and UWM shares dropped nearly 4%.
A Strategic Pivot to “Mortgage-as-a-Service”
This move signals a fundamental shift in Better’s business model. Once primarily a direct-to-consumer lender, the company is pivoting toward a “mortgage-as-a-service” (MaaS) tech platform. Instead of only competing for the loan itself, Better is now selling the “plumbing” of the mortgage process to other financial institutions.
This strategy targets a U.S. Home-loan market that originates more than $1 trillion in mortgages every year. The shift is particularly poignant given the historical trajectory of the market; after the 2008 financial crisis, many traditional big banks, including JPMorgan Chase, reduced their mortgage footprints, leaving a vacuum that was filled by the very non-bank giants Better is now targeting.
By integrating with OpenAI, Better is betting that the future of finance lies in “AI agents” capable of handling complex corporate inefficiencies. The technical execution involves a sophisticated logic tree and a large context window, allowing the AI to cross-reference multiple data points—such as title reports and income metrics—without needing a human to trigger each subsequent step.

The industry will now be watching to see how traditional lenders respond to this automation pressure and whether regulatory bodies will introduce new guidelines regarding AI-driven credit decisions. Better is expected to continue rolling out its MaaS capabilities to more partner firms throughout the coming quarter.
