Inspiration

Medical bills are one of the most confusing and stressful documents people receive. Charges are often unclear, terminology is unfamiliar, and many people don’t know what questions to ask or whether a bill is even correct. We were inspired to build ClearBill after seeing how easily people feel overwhelmed by hospital bills not because they lack intelligence, but because the system isn’t designed for clarity.

What it does

ClearBill helps users understand hospital bills in plain English.

Users upload a hospital bill (photo or PDF), and ClearBill analyzes it to highlight potential billing issues, estimated savings ranges, and clear next steps such as what to ask a billing department or what options may be available. The goal isn’t to give advice or guarantees, but to help users feel informed and confident instead of confused.

How I built it

ClearBill was built as a cross-platform mobile app using Flutter, allowing it to run on both iOS and Android. The app uses OCR and PDF text extraction to read hospital bills and the OpenAI API to generate structured, plain-language explanations and insights.

The app runs in a guest mode with local storage to keep things simple and privacy-focused, and the UI was designed in Figma with an emphasis on clarity, calm visuals, and accessibility.

Challenges I ran into

One of the biggest challenges was handling unstructured documents — hospital bills vary widely in format, terminology, and layout. Ensuring the analysis was informative without over-promising required careful prompt design and strict output validation.

Another challenge was preparing the app for real-world testing across platforms while staying compliant with app store rules around privacy, payments, and medical claims.

Accomplishments that I'm proud of

Building a working iOS and Android app from scratch

Turning complex medical billing information into clear, readable insights

Designing a product that focuses on user trust and transparency

Preparing the app for real testing and hackathon demos

Creating a tool that solves a real, high-impact problem

What I learned

I learned how important clarity and scope control are when building user-facing AI products. Not every problem needs a complex solution sometimes the most valuable thing you can give users is understanding.

I also gained experience with cross-platform development, AI integration, privacy considerations, and designing products that balance technical capability with ethical responsibility.

What's next for ClearBill - Hospital Bill Analyzer

Next steps include improving OCR accuracy for more complex bills, expanding detection of hospital-specific assistance programs, and adding exportable summaries and letters. Longer term, ClearBill could evolve into a broader healthcare cost transparency tool while maintaining a strong focus on privacy and user control.
