NatWest has become the first UK bank to launch a home-buying and re-mortgage guidance app in ChatGPT.

The app will provide customers with NatWest-specific advice which the bank said will allow users to explore mortgage options and make decisions tailored to their needs. in what the bank said is a “more personalised way”.

ChatGPT will draw on publicly available NatWest APIs to calculate how much users could borrow, test affordability and deposit scenarios and receive tailored mortgage rates. By sharing details such as income and outgoings, users will receive responses based on “real numbers”, as well as being able to return to the conversation as their circumstances or queries evolve.

“As technology and AI open up new ways for people to access information and think about their finances, NatWest is focused on meeting customer needs by showing up in the right places at the right time,” said Solange Chamberlain, chief executive of NatWest’s retail banking division.

“Buying a home is a major financial decision, and we want to support those early mortgage planning conversations wherever they may take place,” she added. “By bringing trusted NatWest mortgage guidance directly into ChatGPT, we’re giving consumers more choice in how they explore their options in a more personalised and accessible way.”

Last year, NatWest became the first UK bank to partner with OpenAI, rolling out the company’s artificial intelligence to improve productivity and efficiency throughout the organisation and gaining early access to its latest models.

In February, it announced that customers would soon have access to an agentic financial assistant underpinned by OpenAI’s models, with plans to experiment with voice-to-voice capabilities later in the year.
