I built a script with AI that gathers my expense invoices from Gmail

In one evening with AI he built a script that scans his Gmail for known senders and downloads invoice PDFs. If a supplier sent no PDF, it saves the email itself as a PDF, puts everything together for the office, and logs what it downloaded and sent so nothing goes twice.

How it works

  1. Builds the script with AI in one evening
  2. It scans Gmail by known senders and downloads the PDFs
  3. When no invoice is attached, it saves the email as a PDF
  4. It puts everything together for the office
  5. It runs on three commands and logs what it downloaded and sent

Why it’s worth knowing

The script does the whole chase by itself, even turning a plain email into the invoice PDF when a supplier forgot to attach one, and it keeps a log so nothing is ever sent twice.
