SplitSmart

SplitSmart solves the awkward and time-consuming problem of splitting shared grocery costs between flatmates or household members.

Instead of manually reading a receipt, typing every item, deciding what is shared or personal, calculating each person’s share, and then sending payment requests, users can simply upload a receipt and let the app handle the hard parts.

Solution

The solution is an AI-powered receipt splitting app.

A user uploads a grocery receipt, reviews the extracted items, adjusts any categories if needed, confirms the split, and can then request payment from flatmates.

The app also learns from corrections over time and includes store price comparison based on previously scanned receipts.

Use of AI

AI is used in multiple parts of the workflow.

Claude extracts receipt line items and prices from receipt images, categorizes items as shared or personal, interprets voice commands for quick corrections, and judges whether products from different stores are comparable even when receipt names are abbreviated or written differently.

Modalities

The main non-text modality is image input: users upload receipt photos, and the AI reads and structures the information from them.

The app also integrates audio input through voice commands, letting users update categories or remove items hands-free while reviewing a receipt.

Extra Features

SplitSmart now works with more than just grocery receipts. Users can also upload invoices, such as shared household bills or other common expenses, and split them between the people involved.

The app understands the document, finds the important costs, and turns them into a clear list that users can review before splitting. This makes it useful for both everyday shopping and larger shared payments.

SplitSmart also handles cases where not everything should be split equally. Sometimes one person pays for everyone, but one item is meant for only one roommate. That item can now be marked as personal, so the correct person pays the full amount for it.

Shared items are still divided between the selected people, while personal items are assigned to one person only. This makes the final split much fairer and closer to how people actually shop and live together.

The app also prevents duplicate uploads, so users cannot upload the same receipt twice.
