Batch-convert whole folders of PDFs — scanned or digital — into Markdown files with a quality-first, fully local Tesseract OCR pipeline. Built for poorly scanned documents (fixes rotation, skew, low contrast, shadows) and for large batches (10k+ files, resumable). Works with any Tesseract-supported language and is particularly strong on German (umlauts, ß). Use this skill whenever the user wants to OCR PDFs, convert PDF documents or archives to Markdown or plain text, extract text from scanned documents at scale, or digitize a folder of paperwork — even if they never say the word "OCR".
