His agents watch a WhatsApp group for bills and read each one into his database

A man runs agents called Pi on a VPS behind a small app he had them build. One listens to a WhatsApp group and spots bills, a second Pi with DeepSeek reads each bill, pulls out the amount, due date and reference, and updates the database, and a merge step clears duplicates.

How it works

  1. One Pi agent listens to the WhatsApp group and flags bills
  2. The bill goes into his Django app database
  3. A second Pi with DeepSeek reads it and pulls out amount, due date and reference
  4. The database updates, with a prompt based step to merge duplicates

Why it’s worth knowing

Two small agents pass bills between them like office staff, one watching the chat, one reading and filing each bill.
