Split PDF at separator sheets

I have many PDF files created by a ScanSnap iX500. The ScanSnap also applied OCR. Within each of those PDF files, there exist separator sheets that solely contain the word “Trennblatt”. I want to split the PDF files at every separator sheet. During my research, I came across Python and PyMuPDF. Unfortunately, I don't know how to program. Is there a built-in functionality in Hazel for this task?

This is not something Hazel does. You will need some PDF specific software for that. You might be able to have Hazel trigger it but ultimately that functionality needs to be taken care of by another program.

Thank you!
