The AI use-case library

AI use cases in finance

A catalogue of what AI is actually used for in finance. Each use case is set out the same way, through four lenses: the data, the model, the task, and evaluation and testing. Openly available.

Most AI use cases break down the same way. There is the data it learns from or works on, and whether that data is right for the job. There is the model or method that fits the task, which is often simpler than the hype suggests. There is the task itself, what it actually does, and whether it supports a person or acts on its own. And there is evaluation and testing, how you know it works and where the weak point is. Run any use case through those four lenses and it stops being a vague "AI project" and becomes something you can size, test and govern.

You will notice this catalogue does not sort use cases into risk tiers. That is deliberate. How material a use case is depends on how you deploy it: who it affects and how many, whether a person genuinely re-decides or only approves, whether the action can be reversed, and your own regulatory and fairness exposure. The same use case can be a high-materiality use in one firm and a lower one in another. So each page gives you the four lenses and the questions to ask; you judge the materiality against your own deployment, and let the controls follow. For how that rating is done, see use-case risk and materiality.

This is the finance view. For other industries, see AI use cases by industry, or try the interactive AI use-case explorer. The finance catalogue is below, by area. Each use case links to its own page as it is written. Last reviewed 24 October 2026; to add or correct one, write to gary@quaintitative.com.

Where this fits

This library is the use-case view. Alongside it sit the AI risks taxonomy, which names the risks a use case can carry, and use-case risk and materiality, which sets out how you rate one. For the full step-by-step treatment, see the guide for risk and control functions.
