How to Use AI in Finance?

Artificial intelligence used to be considered experimental in finance. However, it’s obvious that it’s currently reshaping how banks, fintechs, and financial institutions operate. AI is projected to save banks between $200 and $340 billion.

However, many fintech founders and builders are confused about how to use AI in finance. The question isn’t whether AI should be implemented, but rather where to deploy it first, how to implement it responsibly, and what measurable outcomes to expect.

In this article, we’ll give you answers to some of the most important questions in terms of the use of artificial intelligence in fintech companies. 

AI in Finance Explained

Financial AI refers to the use of machine learning, natural language processing, deep learning, and AI agents in financial institutions. There are numerous applications for AI in finance, including fraud detection, credit underwriting, compliance monitoring, customer onboarding, and market analysis. 

Traditionally, software in finance would execute fixed rules. This works well, and it’s reliable. However, financial AI systems learn from data and continuously improve. Some advanced AI systems are also able to take autonomous actions without human input.

For example, AI agents can flag transactions, adjust risk profiles, and escalate certain problems to humans. Yet, human intervention isn’t necessary for the AI agent to take the action. However, it’s worth mentioning that AI in finance often isn’t what people already have experience with.

Generative AI models like GPT-5 and Sonnet 4.6 can be integrated in some capacity for financial institutions, e.g., chatbots, but the AI models used in finance are far more complex. They’re also often specialized for specific processes. 

Types of AI Used in Finance

The foundation of most production systems in finance is machine learning. ML models identify statistical patterns in vast amounts of historical data and apply them to new inputs. For example, scoring a loan application against millions of prior outcomes.

An extended version of ML is deep learning. This is done through the implementation of neural networks with multiple processing layers. It excels at tasks like detecting complex, non-linear relationships in unstructured data. 

A few examples of this would be scanning past reports in order to find inconsistencies or analyzing speech patterns in customer calls. It’s also important to expand on the previously mentioned generative AI, which is the most recent and rapidly maturing category.

Trained on vast corpora, generative models can produce text, synthesize research, draft regulatory filings, and support analyst workflows. The latest and most advanced type of AI in finance is agentic AI. 

While traditional AI mainly responds, agentic AI acts and executes. Agentic AI can plan, reason across steps, call external tools, and execute multi-stage workflows autonomously. This type of AI can be integrated with APIs, which is an important aspect of modern financial services. 

Why AI Is Important in Finance

Finance is a data-intensive and high-stakes domain. Every mistake can cost both the company and its thousands of users. The nature of finance makes it unusually receptive to AI, and unusually exposed to competitive pressure from those who move faster.

The three aspects that drive urgency when it comes to AI adoption include:

• Scale and speed mismatches: High transaction volumes, customer expectations, and increasing regulatory reporting requirements have outpaced what human teams alone can manage. AI removes a lot of bottlenecks caused by human errors and manual labor. 
• Data richness: Financial institutions hold decades of structured transaction data, behavioral records, and document archives. That is exactly the substrate on which AI models improve. The more data a company has gathered, the more effective AI implementation can potentially be. 
• Competitive pressure: Large institutions in this industry are already deploying AI natively. To keep up with major competitors, fintech companies should aim to leverage AI in order to keep up with the market. 

The results of AI implementation are measurable. Companies can easily observe whether AI has helped them reduce manual workload, onboarding time, servicing costs, and other important numbers that can have a significant impact on the company’s effectiveness. 

Benefits of AI in Finance

The case for AI in finance is not theoretical. Institutions that have moved beyond pilots are reporting measurable, compounding returns across five categories: operational efficiency, risk reduction, revenue growth, regulatory compliance, and competitive positioning. 

Depending on the size of your company and the number of transactions you’re dealing with, these benefits can vary in their impact. 

Where to Use AI in Finance

Like all technologies and concepts, agentic AI in finance doesn’t work like magic, and it won’t solve all of your problems at once. Instead, you should understand the key areas where AI can bring crucial benefits. 

Fraud detection and risk monitoring

Fraud detection is the highest priority AI application across financial services, and for good reason. Financial institutions are susceptible to cyberattacks and fraud, and minimizing the chances of these succeeding is crucial.

Agentic AI for fraud detection​ does not just flag suspicious transactions, they investigate, correlates, and acts. When an anomaly is detected, an agentic system can cross-reference account history, pull behavioral data from connected systems, simulate fraud scenarios, and either freeze an account or escalate to a human analyst, all within milliseconds. 

Credit scoring and lending decisions

Traditional credit scoring is a narrow, backward-looking process. It relies primarily on credit bureau data, which excludes large segments of the population, like the underbanked, recent immigrants, young adults, and small business owners with unconventional income patterns.

AI-powered credit models evaluate a substantially wider feature space: real-time income stability, transaction velocity, payment behavior across categories, employment patterns derived from payroll data, and, in some markets, alternative data sources such as utility payment history.

The operational benefits are equally significant. Agentic loan underwriting systems can evaluate a complete application document verification, credit analysis, fraud screening, and compliance checks in minutes rather than days.

KYC, AML, and compliance automation

Compliance is among the highest-cost functions in financial services, and among the most amenable to AI automation. 

Know Your Customer (KYC), Anti-Money Laundering (AML), and broader regulatory reporting require processing vast volumes of documents, screening against constantly updated watchlists, and monitoring every transaction against complex and evolving rule sets.

The manual version of this process is slow, expensive, and error-prone. Automating KYC makes the whole process continuous and scalable.

AI-powered KYC systems combine several capabilities: optical character recognition and document classification to extract data from identity documents, NLP to cross-reference against sanctions databases and adverse media, behavioral analytics to flag anomalous account activity post-onboarding, and machine learning to continuously refine risk scoring as new signals emerge.
