Text Extraction
Text Extraction is the engine behind search, read-aloud, and SEO. It mines per-page text from the source PDF using a two-tier fallback: smalot/pdfparser for fast PHP-only extraction, and the pdftotext system utility for encrypted or otherwise stubborn PDFs. Cached after extraction, re-runs only when the PDF changes.
What you get
- Two-tier extraction with automatic fallback
- Handles encrypted PDFs that pdfparser can't
- Cached per-PDF in post meta
- Re-extracts only when source changes
- Powers search, read-aloud, AI chatbot
