Mama POS needed a way to record bank transfer alerts without manual notebook entry, verify balances, and generate end‑of‑day summaries while keeping all data offline.

The app correctly parsed all 5 real alerts with 5/5 kind accuracy and 4/5 name accuracy, and 30/30 synthetic alerts for kind and 23/30 for name. It runs offline after a one‑time 859 MB download and works on devices with a GPU.

• Paste the email alert into the input field.
• Code extracts time, amount, and kind of money.
