Ethan Bloch, product lead for ChatGPT Finances at OpenAI and co-founder of Digit (10 million users, $9 billion saved), walks through six concrete ways to use ChatGPT for personal finance. The use cases include finding wasted spending, reducing tax liability, optimizing credit card rewards, and modeling major financial decisions.
What makes this worth reading in full is not just the list. Bloch built Digit, so he understands behavioral finance at scale, and his framing of where AI actually adds value versus where it falls short is grounded in that product experience. The interview is structured by timestamp, so you can skip directly to the use case most relevant to your situation.
The broader implication: OpenAI is positioning ChatGPT as a financial planning layer, not just a chatbot. Bloch is the person shaping that product. Understanding his mental model now tells you where this category is heading.
