Zplit

Zplit is an expense splitting tool that doesn't require downloads or signups – just scan a receipt, assign items, and split the bill.

Background

I had the idea to design an expense splitting app when I was on a group trip with friends and we struggled with the existing apps; mandatory downloads, signups, and difficulty calculating unequal expenses. When vibecoding (AI-assisted coding) became accessible, I took the opportunity to turn my idea into a working prototype.

Concept

A common behaviour I noticed across different friend groups, is that we often keep the receipt or take a photo of it, then split the bill later. So for the first feature, I decided to build an OCR receipt itemizer that doesn't require account creation or sign ups. The flow is kept simple: scan/upload receipt > review receipt line items > assign group members to item > share summary with friends.

Design

What's next

Since this is a self-initiated project, I can only work on this in pockets of free time but I hope to build out the full features of the app into something I can use and share with the rest of the world. Below are some items in progress.

• Group multi-expense flow + testing
• Iron out details in the UI
• Logo

Reflections

I started this project to experiment with AI tools, vibecoding actually made me more interested in learning to code properly. While it could generate code quickly, my knowledge of coding is not deep enough to be able to tell when something was wrong or if there was a better approach than what was suggested by AI. It gets dangerous when you blindly accept AI output, and that's what's pushing me to learn.
