Diaty Split Bill – A Minimalist Tool for Splitting Bills & Group Payments

What is the product

Diaty Split Bill is a web application that aids in calculating and splitting restaurant bills, travel expenses, and group spending, designed as a minimalist web application optimized for Vietnamese users.

A positioning statement

This intelligent group bill-splitting tool accurately calculates each person's share (including item cost, VAT, discounts, service fees) and divides the money fairly in just a few seconds right in the browser.

The problem it solves

Whenever dining out, traveling in groups, or organizing events, splitting the bill often causes headaches and takes time: some people eat this dish but not that one, the bill may include discount codes (vouchers) or service/VAT fees that complicate fair allocation, and the person who pays upfront may feel awkward when asked for reimbursement. Diaty Split Bill completely resolves this pain by automatically allocating VAT/discounts based on the proportion of each item, calculating every cent accurately, and creating a transparent summary transfer.

Main features

• Split payments by item: Allows assigning each dish/drink accurately to those who participated in consuming that item, instead of just dividing the total bill cumbersome way.
• Automatic allocation of VAT, service fees & discount vouchers: Automatically calculates and evenly distributes any additional fees or discounted amounts based on the proportion of each person's share of the dish value.
• Create a payment summary: Compiles the list of amounts each person needs to reimburse in just one tap.
• Manage member lists & payment history: Stores your friends' list and history of the bills just split directly in the browser for easy reference and reconciliation when needed.
• Zero ms calculations & No registration required: All calculations are processed immediately as you type, no account creation needed, no worries about intrusive ads.

Real-life example when used:

• Splitting a restaurant bill: Enter the total bill of 1,200,000 VND along with a 10% discount voucher and 8% VAT. Assign Hot Pot (500,000 VND) to 4 people, Grilled Dish (300,000 VND) to 3 people, and Drinks to the group ➔ The system automatically calculates precisely the exact amount for each person down to the thousand VND and produces a summary.

Who should use it

• Office workers & Colleagues: Need to quickly and easily split lunch costs, avoiding confusion.
• Friends traveling / Picnic groups: Need to manage and summarize shared expenses - private expenses throughout the trip.
• Students & Roommates: Need to transparently split rent, utility bills, and monthly communal purchases.

How to get started

• Supported platforms: Web browsers (Chrome, Safari, Edge, Firefox) on all PC, iOS, and Android devices. Supports "Add to Home Screen" to use conveniently like a native app.

• Steps to use right away:

  1. Directly access the address diaty-split-bill.vercel.app in the browser.
  2. Enter the list of participants and the list of dishes/expenses along with any discounts or VAT (if applicable).
  3. Select the users corresponding to each dish and copy the summary for the entire group.

Differences & Security benefits

Unlike traditional payment-splitting apps that require the whole group to download an app, register an account, and synchronize data to a server (which can be cumbersome and poses a risk of exposing personal spending information), Diaty Split Bill operates 100% on your browser.

• Super fast response: The calculation algorithm runs directly on your device at 0ms speed.
• Security & Minimalism: Does not collect or store your financial data or dining history on any intermediary servers. Your information is completely private and belongs to you.
