What it is

Tracking expenses by hand is the reason nobody does it. So I automated the boring part: forward a statement or a receipt and it gets read, categorized and logged — no spreadsheet gymnastics.

Under the hood it's an n8n workflow wired to GPT-4o, a Next.js upload app and Google Sheets. Self-hostable with Docker, open source, and shared publicly so anyone can fork it and run their own.
