Overview

No overview available.

Problem

  • Shared expenses are easy to forget, frustrating to split manually, and especially messy when a single receipt includes both shared and personal items.
  • I wanted a private workflow that could ingest a receipt photo, extract line items, assign participants, and maintain running balances across the household.

Solution

  • Built a self-hosted household expense workflow combining receipt upload, OCR extraction, itemized review, and balance tracking.
  • Expenses can be recorded without relying on third-party consumer finance apps.

Workflow

  1. 1

    Upload receipt from phone or desktop

  2. 2

    OCR-based text extraction

  3. 3

    Convert to candidate line items

  4. 4

    Review as structured shared expenses

  5. 5

    Assign participants and track balances
