First Internet Bank Embraces AI for Digital Banking

First Internet Bank is taking another step in its digital-first journey by embracing artificial intelligence as a new way for customers to interact with their financial information.

The Indiana-based bank, founded in 1999 as one of the earliest online-only banks, is testing a Model Context Protocol (MCP) integration that allows customers to connect eligible bank accounts with AI assistants such as ChatGPT and Claude.

The idea is simple: instead of navigating through multiple banking screens to find an answer, customers can ask questions about their finances in everyday language.

Turning banking data into a conversation

With the AI integration, customers can ask questions such as:

• Do I have enough cash to cover my upcoming bills?
• How has my spending changed over the past few months?
• Which subscriptions or vendors have I paid recently?
• Has a particular transaction posted?
• What trends are emerging in my cash flow, revenue, or expenses?

This represents an important shift in digital banking. Rather than simply providing customers with dashboards and transaction lists, banks can potentially make financial information easier to understand through conversational AI.

Security remains central

First Internet Bank's approach is deliberately cautious.

The MCP connection is optional and requires customers to authorize access. Customers can control what information is shared and can revoke access. Importantly, they do not provide their online-banking username or password directly to the AI assistant.

The AI connection is also read-only. It can analyze authorized financial information, but it cannot transfer funds, make payments, change account settings, or otherwise take financial actions on the customer's behalf.

That distinction is significant. As financial institutions explore AI, allowing an AI system to understand financial information is a very different proposition from allowing it to acton that information.

An early glimpse at AI-powered banking

The service remains in beta and has limitations. For example, customers cannot use the AI connection to access actual bank statements or tax-document files, nor can they use it to initiate certain customer-service processes.

Still, the experiment points toward a potentially important direction for digital banking.

For years, banks have invested heavily in making their websites and mobile apps easier to navigate. Generative AI introduces another possibility: customers may not need to navigate at all.

Instead, they could simply ask a question and receive an explanation based on their own financial data.

For First Internet Bank, this approach is a natural extension of its history as a digital banking pioneer. For the broader financial-services industry, it offers a glimpse of a future in which the primary interface for banking may be less about screens, menus, and buttons—and more about conversation.

The challenge will be finding the right balance between convenience, security, privacy, and customer control. If banks can get that balance right, conversational AI could become one of the most significant changes to the digital banking experience in years.
