Your AI Financial Assistant

Earlier chapters included prompts for specific tasks. This chapter is your reference library — a collection of ready-to-use prompts covering the full range of personal finance questions.

These prompts work with Claude, ChatGPT, and other capable LLMs. Copy them, customize the bracketed sections, and use them whenever you need financial clarity.

How to Get Better Responses

Before the prompts, a few principles that make any financial prompt more effective:

Include your actual numbers. "I make a decent salary" gives worse advice than "I make $75,000/year." Specifics enable specific advice.

State your constraints. Mention what you can't or won't change. "I'm not willing to move" or "My spouse handles our taxes" prevents irrelevant suggestions.

Describe your goal, not just your question. "I want to know about Roth IRAs" is weaker than "I want to minimize lifetime taxes and am wondering if a Roth IRA makes sense for my situation."

Ask for reasoning. Adding "explain your thinking" helps you evaluate whether the advice makes sense for you.

Iterate. The first response rarely answers everything. Follow up with clarifying questions or ask the AI to go deeper on specific points.

Using These Prompts Effectively

A few final notes:

Customize aggressively. The prompts are templates. Add your details, remove irrelevant sections, and adjust to your situation.

Verify important information. LLMs can be wrong about tax rules, account limits, and current regulations. Cross-reference anything consequential.

Save prompts that work. When you get a useful response, save both the prompt and response for future reference.

Return to prompts over time. Your finances change. Running the same analysis annually (or after major life events) keeps you on track.

What's Next

Prompts help you think clearly. But some financial tasks are just tedious — taxes, document organization, receipt tracking. Chapter 6 covers how AI tools handle the administrative side of personal finance.
