Banks Are Using AI — Here’s What Consumers Need to Know

You might use AI to write emails at work, plan vacations or shop online. But we’re not the only ones using artificial intelligence to make life easier. Financial institutions, from lenders to investors to banks and credit unions, have turned to artificial intelligence in recent years. But how are banks using AI?

Bank AI usage has moved far beyond customer service chatbots on websites. Financial institutions now use AI to detect fraud, make lending and investment decisions and automate everything from portfolio management to solving customer issues.

It’s important to understand how your bank uses AI. Although it might have some benefits, like faster credit decisions and around-the-clock customer service, it could also have major drawbacks, like putting your financial information at risk and unfair lending practices.

Below, we’ll cover how major banks are using AI, the potential benefits and pitfalls, what to ask your bank about how it uses AI, and how to protect your money and personal information.

Why Are More Banks Using AI?

Banks are turning to artificial intelligence for several reasons, including efficiency and cost savings. Banks handle millions of customer transactions and requests each day. AI can help them process information faster without requiring employees to handle every task.

For instance, an AI-powered tool could answer a customer’s question about a recent transaction, flag a potentially suspicious purchase or summarize a customer service conversation (which might have been managed by an AI chatbot to begin with). Automating these tasks frees bank employees to focus on more complicated issues requiring a human touch.

But not all AI works the same. Traditional AI is often designed to recognize patterns, analyze data and make predictions. Banks use this type of artificial intelligence to spot unusual spending activity or help assess someone’s creditworthiness, like when they apply for a credit card or loan.

Generative AI, on the other hand, creates new content, like written responses and conversational answers. This is the tech that powers many of the chatbots and virtual assistants you’ve likely encountered in your everyday life.

Just because a bank is using AI doesn’t mean a computer handles everything, though. Some AI tools simply give employees information to do their jobs; others might automate specific, repetitive tasks.

What Should You Do If Your Bank Is Using AI?

Don’t assume your bank’s not using AI just because you haven’t interacted with a chatbot lately. Many financial institutions use artificial intelligence behind the scenes. So you know there are banks using AI, but is yours one of them?

Start by checking your bank’s website, mobile app or privacy policy for information about its technology. You can also contact customer service and ask directly — though, be warned, it’s possible you might get your answer from an AI chatbot!

How and if a bank uses AI should be a consideration when choosing where to open an account or apply for a loan. But you shouldn’t necessarily switch banks because yours uses AI; rather, you should weigh the pros and cons of how your bank uses AI. More importantly, you should choose a bank that offers low fees, high yields on savings and top-notch security features to protect your money. Plus, some banks offer sign-up promotions so you could earn money for switching.

Before choosing a bank, consider its policies, security practices and technology usage by asking the following questions:

What to compare	Questions to ask
Monthly fees	Does the account charge a monthly maintenance fee? Can it be waived?
Overdraft policies	What happens if I spend more than my available balance?
Customer service	Can I reach a person when I need help?
Security	Does the bank offer transaction alerts and strong account protections?
Privacy	Does the bank explain how it collects and uses customer information?
Access	Are branches, ATMs and digital services convenient for me?
Dispute resolution	Does the bank explain how to report problems and challenge errors?
AI transparency	Can the bank explain how its AI tools affect customers?

What Are Banks Using AI For?

Many banks in the U.S. already use AI in ways that could impact you:

Answering customer service questions

AI powers bank chatbots to answer your questions online quickly and accurately — and at any time of the day. Virtual assistants can also help you navigate a mobile app and check recent transactions. Bank of America’s AI-powered virtual assistant, Erica, can help with these and other tasks inside the mobile banking app.

Detecting fraud and suspicious transactions

Banks like Capital One use AI to identify unusual transaction patterns and flag potential fraud. If you only swipe your card for everyday purchases in your hometown, but then there’s suddenly an extravagant purchase in another country, AI may flag that transaction. The Government Accountability Office (GAO) reports that banks may also use AI to identify fake IDs, detect money laundering and recognize signs of insider trading and tax evasion. 

Evaluating loan and credit applications

Many lenders, including Upstart, use AI when making lending decisions. When you apply for a credit card, personal loan or other type of loan, AI may review your credit report, bank statements and other documentation to recognize patterns and predict your creditworthiness. 

Offering personalized financial insights

There are banks using AI to offer insights about your spending habits and savings goals. Such tools can help you make a budget or even flag upcoming potential cash-flow problems. For instance, Wells Fargo’s virtual assistant, Fargo (the names leave a little something to be desired), can analyze your account and offer personalized recommendations based on your stated goals.

Helping employees work more efficiently

AI can summarize customer interactions, search internal documents and help bank representatives find relevant information — but now, companies are getting even more strategic with how they use it.

For example, in June 2026, JPMorganChase outlined how it’s using AI to bring products to market more quickly. Bank of America employees use EricaAssist, a generative AI tool, on the back end to help resolve client issues faster, while Wells Fargo teams use the AI-powered Intelligent Banker Book to better prepare for client meetings.

At banks across the country, engineers may use AI to write website code or develop new product offerings. Marketers could use AI to draft messaging or create assets. Accountants often use AI-powered software to expedite tax filing. AI can truly touch every corner of the business. 

Potential Benefits of Banks Using AI for Consumers

AI is a divisive topic. But there are ways banks using AI can benefit you as a consumer, including:

• Easier budgeting and money management. AI-powered insights can help you track spending habits and recognize recurring expenses. AI may even flag when it anticipates an upcoming shortfall in your bank account.
• Faster help. Traditionally, bank customer service representatives may have only been available during certain hours on certain days of the week. With AI chatbots, you can seek out help any time (like when you notice something fishy with your account at 3 a.m.) and get a resolution faster — no waiting on hold for hours.
• Better fraud detection. AI can identify suspicious activity more quickly. This can significantly reduce the amount of time a criminal has access to your account. That said, AI detection is not a guarantee against fraud. You should absolutely still monitor your finances closely and report any suspicious activity immediately.

In many cases, these and other efficiencies have led to operational cost savings for banks. Theoretically, banks could pass those cost savings onto consumers via lower fees or better benefits, though there’s no guarantee that will happen.

What Are the Risks of Banks Using AI?

There’s a flip side to every coin. While AI in banking offers a number of benefits, there are real risks of banks using AI, too, including the following:

AI Can Make Mistakes

Humans make mistakes, but so does artificial intelligence. AI-generated answers may be inaccurate, incomplete or even misleading.

A chatbot could provide incorrect information about a fee or bank policy. Without verifying the information provided, you may make a decision that has a negative impact. For instance, a chatbot may incorrectly say your credit card has no foreign transaction fee, so you swipe it the next time you’re abroad — and then notice a hefty fee with the transaction.

AI Could Lead to Unfair Lending Decisions

AI can expedite underwriting for loans and help lenders make decisions about applicants who don’t have an established credit history. But if that AI was designed with bias or trained on flawed data, it could produce biased outcomes, especially for low-income borrowers or borrowers with nontraditional finances (like those on disability or self-employment income).

Just because your loan application is denied doesn’t automatically mean the decision was discriminatory. But if there’s no clear explanation for why your application was denied, ask for more information. Banks that use AI in lending decisions must still comply with all fair-lending and consumer-protection requirements.

Your Personal and Financial Information Could Be at Risk

To perform their functions, AI tools may have access to sensitive account information and other personal data. That creates potential risks if information is exposed, accessed by unauthorized people or shared with outside tech companies that help banks run their AI.

Before using an AI-powered banking feature, check your bank’s privacy policy to understand what info it collects, how it’s used and if it’s shared with third parties.

It May Be Harder to Reach a Human

AI may give you around-the-clock customer service access, but a bank’s growing reliance on AI chatbots and automated phone systems may mean fewer actual human customer service representatives. This could lead to frustration when you need human help quickly, like when your account’s frozen or you need to dispute a fraudulent charge.

If an automated tool isn’t getting you the help you need, ask to speak with a human.

AI Could Make Fraud More Convincing

Banks may have AI to protect against fraud — but criminals can use AI, too. Fraudsters can use AI to create realistic phishing emails and texts, impersonate bank employees or even clone someone’s voice. That means a message that sounds legit might not actually be legit.

If you get a suspicious message or call, don’t click links or share personal information. Instead, contact your bank through its official app, verified website or the phone number on the back of your card.

Automated Decisions Can Be Difficult to Understand

It might not always be clear when AI played a role in a bank’s decision or what information influenced the outcome. This is especially problematic when you’re applying for a loan and don’t understand why you were denied.

If a decision seems incorrect or unfair, ask the bank for an explanation and find out if you can request a review. For credit denials, federal law generally requires lenders to provide specific reasons for decisions, even when they use complex AI-powered algorithms.

Possible Higher Fees

In the race to implement AI faster than competitors, some banks have invested a lot of money in the technology. In many cases, banks may offset those investments through higher fees and interest rates.

How to Protect Your Account

Worried about your bank using AI? Here’s how to protect your account:

1. Find Out How the Bank Is Using AI

Start by understanding if and how your bank uses AI. You can typically find this info on your bank’s website, particularly in its privacy policy and disclosures. You can also reach out to customer service to learn more.

Consider asking:

• How AI is used, including for customer service, fraud detection and lending
• If AI has access to your account info
• How you can opt out of optional AI-powered services*
• If a human is available to review important decisions

*While you may not be able to opt out of every internal bank application, clarify whether you can opt out of AI-powered customer facing features.

2. Protect Your Login Information

Don’t ever share login information for important accounts — bank or otherwise — with third-party AI applications. Similarly, you shouldn’t share these details with unverified chatbots or callers.

To further protect your account against criminals using AI, create strong, unique passwords and turn on multifactor authentication. This is a crucial feature for all online banking; don’t open an account at a bank that doesn’t offer this.

AI has recently made headlines for accessing bank accounts using customers’ login credentials. To be clear, this is not a bank’s own AI, but rather a security threat using AI to hack into customer accounts. Strong passwords, multifactor authentication, and frozen credit reports are your best defense against these threats.

3. Check Your Transactions Regularly

Your bank should be constantly monitoring your account (and likely uses AI to do so), but that doesn’t mean you should get complacent. You should regularly check your checking and savings account activity manually and flag any suspicious activity.

Ideally, choose a bank that has transaction alerts in the mobile app or via text. With these alerts on, you’ll be notified instantly any time your card is swiped or your account is debited.

How to Dispute AI Decisions

Bank AI can get things wrong. Here’s how to dispute AI decisions.

Ask for a Human When There’s a Problem

Banks are increasingly using AI for customer communication, but you should still be able to contact a human when you need help. Ask for a human representative if you:

• Notice an incorrect or fraudulent transaction
• Are confused about any account fees or restrictions
• Don’t understand a credit decision
• Are facing a financial hardship and need personalized assistance

Always take notes during phone conversations and archive all relevant email communications. Keep copies of mail notices, and ask for a case or reference number for more involved issues.

Challenge Decisions That Seem Wrong

If you think a bank made a decision based on incorrect information, ask what information it used and review it to make sure it’s accurate. You can also request a review or reconsideration if the bank offers one. Keep copies of any denial notices, account statements and communications with the bank in case you need them later.

And if the issue isn’t resolved, you may be able to file a complaint with the Consumer Financial Protection Bureau (CFPB) or the appropriate banking regulator.

Does Your Bank Have to Tell You When It Uses AI?

There’s not a blanket rule that requires banks to tell customers every time they use artificial intelligence. For instance, a bank doesn’t have to announce if an employee used AI to code a webpage or summarize a customer service call. And if a bank uses AI to detect suspicious transactions behind the scenes, it doesn’t necessarily have to notify you each time the technology is involved.

However, other consumer protection laws still apply when it comes to banks using AI. If AI plays a role in your loan application denial, for example, the Equal Credit Opportunity Act requires the lender to provide specific reasons for the denial. The Gramm-Leach-Bliley Act also requires banks to disclose certain information about how they collect, share and protect your personal financial information. In other words, AI doesn’t give a bank a free pass to ignore existing consumer protection requirements.

The Bottom Line on Banks Using AI

Banks are increasingly turning to AI for everything from customer service and fraud detection to lending analysis and employee productivity. When implemented correctly and safely, bank artificial intelligence can mean faster support, better fraud monitoring and useful financial insights that help you save and spend more intelligently.

But AI comes with risks, too. That may include privacy concerns, bias in lending and difficulty reaching a real human when you need help with something more complex. That doesn’t mean you should avoid banks using AI — it’s hard to find banks that aren’t using it, after all. Rather, it means you should learn how your bank is using AI, protect your login credentials, monitor your finances closely and seek human assistance when your money’s on the line.
