reepub
**Bind your own paper into a personal library.**
Not a file converter — a capability you own: studio-grade OCR that lives on your shelf, not someone's cloud. A native macOS tool that turns the scanned PDFs you own into clean, reflowable, validated EPUB3 books. Apple Vision OCR, Traditional Chinese + English, everything processed on your own Mac and never uploaded.
How it works
1.
Pick a PDF
Open the native app and choose a scanned PDF, or drag it onto the window. Apple's Vision framework runs OCR entirely on-device — Neural-Engine-accelerated on Apple Silicon.
2.
Set the metadata
Give the book a title and, optionally, an author or source. reepub stitches OCR lines back into real paragraphs and splits chapters from heading cues.
3.
Save the EPUB
Hit Save EPUB — reepub assembles a standards-compliant EPUB3 (cover, table of contents, per-chapter XHTML), runs a built-in validator, and writes the finished book. Nothing ever leaves your Mac.
What's inside
You own it, not rent it
Cloud OCR is a borrowed library card — revocable, priced per page, your files routed through someone else's servers. reepub is the book on your own shelf: free, offline, yours. No one can reprice it or switch it off.
Apple Vision OCR
On-device text recognition, Neural-Engine-accelerated on Apple Silicon, with Traditional Chinese and English out of the box.
Truly reflowable
Text is rebuilt into real paragraphs and chapters that reflow on any screen — not a frozen page image. Low-text pages are preserved as image plates.
Validated EPUB3
Every book passes a built-in, dependency-free structural validator before it's handed back — auto cover, table of contents, and chapter detection included.
Your paper, your library
Free and open source — yet its headline is exactly what paid clouds can't sell you: ownership, privacy, permanence. reepub is for digitizing documents you own or have the right to digitize, into a personal ebook library you keep locally. Build it from source with the Xcode Command Line Tools — no full Xcode, no cloud, no cost.
