Hearth: An AI household finance assistant

The Challenge

Managing household finances is rarely just about budgeting. Families often have money spread across multiple accounts, recurring bills, subscriptions, school expenses, and unexpected costs that make it difficult to understand their true financial position.

While banking apps provide transaction histories and account balances, they rarely answer the questions households care about most:

  • Can we afford this purchase?

  • Are we on track this month?

  • Will we have enough money after upcoming bills?

  • How much can we safely save?

Many families only discover financial problems after they occur, such as when an account balance drops unexpectedly, a bill is missed, or spending exceeds what was planned.

I saw an opportunity to create a financial assistant that shifts money management from reactive to proactive.

This insight led to the concept for Hearth: an AI-powered household finance assistant designed to help families understand their financial health, anticipate future risks, and make confident financial decisions before problems arise.

Project Goals

The primary objective was to design a product that gives households greater visibility and confidence in their day-to-day financial decisions.

Key goals included:

  • Help users understand their financial position at a glance.

  • Predict financial risks before they occur.

  • Reduce the stress associated with managing bills and household expenses.

  • Provide personalized financial guidance without requiring financial expertise.

  • Help users make informed spending and saving decisions.

  • Create a financial experience that feels supportive and approachable rather than intimidating.

Success would be measured by how quickly users could understand their financial status, identify potential risks, and make confident financial decisions.

Research and Validation

To better understand household financial behaviors, I explored existing budgeting tools, banking apps, personal finance communities, and user discussions around money management.

Several themes emerged:

  • Most people check account balances but struggle to understand what those balances actually mean.

  • Budgeting tools often require significant manual effort to maintain.

  • Households worry more about future expenses than past spending.

  • Financial stress frequently comes from uncertainty rather than an actual lack of money.

  • Users want guidance but do not want to feel judged or overwhelmed.

One recurring theme stood out:

"I know how much money is in my account, but I don't know if I'm actually okay."

This became the foundation for the product experience.

Design Process

1. Understanding Existing Financial Tools

I reviewed the experience offered by traditional banking and budgeting applications.

The typical experience looked like this:

Check account balance → Review transactions → Open budgeting tools → Manually calculate upcoming expenses → Estimate future spending → Make a financial decision

This process required users to interpret complex financial information on their own.

2. Reframing the Problem

Rather than asking:

"How can we help users track their finances?"

I reframed the challenge as:

"How might we help households understand their financial future with confidence?"

This shift moved the focus away from reporting financial data and toward providing actionable guidance.

3. Ideation

I explored several product directions:

  • Traditional budgeting dashboard

  • Savings-focused assistant

  • AI-powered financial coach

  • Household planning calendar

  • Predictive financial health system

User feedback and concept testing consistently favored proactive financial forecasting combined with conversational AI guidance.

The strongest concept became a system that combines financial monitoring, risk prediction, and personalized recommendations in one experience.

Key Design Decisions

Leading with Financial Health

Most financial apps prioritize balances, transactions, and budgets.

Hearth instead begins with a simple question:

"Am I okay this month?"

The Financial Health Dashboard provides a clear answer using a household health score, spending forecasts, and available-to-spend calculations.

This reduces the need for users to interpret multiple financial metrics on their own.

Predicting Problems Before They Happen

Many financial tools alert users after an issue has already occurred.

Hearth introduces a dedicated Risk Alerts experience that identifies potential problems before they happen, such as:

  • Running out of grocery budget

  • Upcoming bills exceeding available funds

  • Potential low-balance situations

This proactive approach helps users take action early rather than react to surprises.

Conversational Financial Guidance

Financial planning can feel intimidating, especially for users who are unfamiliar with budgeting terminology.

To make financial information more accessible, I introduced Hearth AI, a conversational assistant that allows users to ask questions in natural language.

Examples include:

  • "Can we afford a weekend trip?"

  • "Why is spending higher this month?"

  • "Can I move money into savings?"

The AI provides personalized explanations and recommendations based on the household's financial situation.

Reflections

This project challenged me to think beyond budgeting features and focus on a deeper emotional problem: financial uncertainty.

The biggest insight was that households don't necessarily need more financial data. They need help interpreting that data and understanding what it means for their future.

By combining predictive insights, conversational AI, and proactive risk management, Hearth transforms financial management from a stressful guessing game into a clearer and more confident decision-making experience.

The project also reinforced the value of designing for reassurance. The most important feature was not the AI itself, but the ability to answer a simple question every household asks:

"Are we okay?"
