🫧 BUBBL — Your Money, Smarter Together

An AI-powered platform reimagining shopping, personal finance, and shared financial management through Visa and Hyphenate.

💡 Inspiration

Managing money shouldn't be complicated, but for many people, especially college students, roommates, couples, and young adults, it often is.

We've all experienced buying groceries only to discover that another store had better prices, struggling to split bills with roommates, losing important receipts, or wondering where our money went at the end of the month.

Most financial applications focus on showing users where their money went, but we wanted to create something that helps people make smarter decisions about where their money should go next.

We asked ourselves:

What if one application could help you shop smarter, manage your finances, split expenses, and save money without making everything feel complicated?

That question inspired BUBBL, an AI-powered shopping and financial management platform designed to make financial intelligence accessible, interactive, and collaborative.

🚀 What It Does

BUBBL combines intelligent shopping, financial management, and shared expense coordination into one platform.

🧾 1. AI-Powered Receipt Scanning

Users can scan or upload receipts, allowing AI to identify:

  • Individual purchased items
  • Product prices and quantities
  • Store and merchant information
  • Transaction totals
  • Spending categories

Receipts can also be stored digitally for future reference, expense tracking, and reimbursement purposes.

🛒 2. Smart Shopping Recommendations

BUBBL analyzes shopping patterns to help users discover opportunities to save money.

The platform is designed to:

  • Compare shopping options across stores.
  • Identify potentially cheaper alternatives.
  • Recommend smarter purchasing decisions.
  • Help users plan grocery shopping around their budgets.
  • Recognize recurring purchasing habits.

Our goal is to help users save money before they spend it, not just track expenses afterward.

💰 3. Personalized Budgeting

Users can enter their income, expenses, and financial goals.

BUBBL helps organize their money into categories such as:

  • Groceries
  • Rent and utilities
  • Transportation
  • Entertainment
  • Emergency savings
  • Personal financial goals

The platform helps users understand their spending patterns and make financial decisions aligned with their priorities.

👥 4. Shared Financial Management

BUBBL is designed for more than individual users.

Roommates, couples, newlyweds, and families can manage shared financial responsibilities through collaborative financial spaces.

Users can:

  • Track shared household expenses.
  • Split bills and purchases.
  • Calculate individual contributions.
  • Organize shared financial goals.
  • Maintain separation between personal and shared expenses.

🫧 5. Interactive Financial Dashboard

We wanted to make financial management feel less intimidating.

Instead of relying entirely on traditional spreadsheets and charts, BUBBL introduces a bubble-inspired financial dashboard.

The interface is designed to help users visualize spending categories, savings goals, and financial priorities in a more engaging and understandable way.

💳 Reimagining Shopping with Visa

We integrated Visa into BUBBL as part of our vision to connect intelligent shopping with modern payment experiences.

Our approach focuses on three important areas:

  1. Smarter Shopping: Helping consumers understand purchasing decisions and identify potential savings.
  2. Personalized Commerce: Creating shopping experiences informed by individual spending patterns and financial priorities.
  3. Consumer Confidence: Making financial information more transparent and easier to understand.

Rather than treating shopping and budgeting as separate activities, BUBBL brings them together.

We believe the future of shopping isn't simply about making purchases faster. It's about helping people make better purchasing decisions.

🤖 Intelligent Financial Workflows with Hyphenate

We also integrated Hyphenate to support our vision of intelligent financial coordination.

Managing finances often involves repetitive tasks, including organizing expenses, tracking shared payments, and coordinating household responsibilities.

BUBBL explores how AI-powered workflows can simplify these processes.

Our goal is to create a financial experience where technology assists users with routine tasks while maintaining transparency and user control.

By combining intelligent commerce with financial workflow automation, BUBBL aims to make everyday money management simpler and more connected.

🛠️ How We Built It

We developed BUBBL by bringing together AI-powered shopping intelligence, financial management, and collaborative expense coordination.

Our development process focused on three major components.

1. AI and Receipt Intelligence

We worked on transforming receipt information into structured financial data.

This involved identifying purchases, organizing transaction information, and making spending data useful for financial analysis.

2. Financial Management and User Experience

We designed the platform to connect everyday shopping activity with budgeting, expense tracking, and personalized financial insights.

We also focused on creating an engaging interface that makes complex financial information easier to understand.

3. Visa and Hyphenate Integrations

We incorporated Visa and Hyphenate to explore intelligent commerce and automated financial workflows.

These integrations helped us connect our broader vision of smarter shopping with more efficient financial management.

🚧 Challenges We Faced

Integrating Multiple Financial Features

One of our biggest challenges was combining receipt scanning, shopping recommendations, budgeting, and shared expense management into one seamless application.

Each feature involves different types of financial information, making it challenging to create a consistent user experience.

Working with External Integrations

Integrating Visa and Hyphenate introduced additional technical complexity as we worked to connect external technologies with our application's functionality.

Balancing AI with Accuracy

Financial information requires precision.

We had to consider how to use AI responsibly while maintaining accurate calculations, transparent recommendations, and appropriate user control.

Time Constraints

Building BUBBL during Cal Hacks 13.0 challenged us to balance our ambitious vision with the limited time available.

We had to prioritize functionality while maintaining a clear direction for the platform.
