How It Works
Your library. Everywhere.
Book Binder connects the books already on your computer to a beautiful reading experience on every device you own — without moving or uploading your files.
Install the Desktop Agent
Download the small background app for Windows. It runs quietly in your system tray — no setup wizard, no configuration file to edit.
The agent is what connects your local files to the web. Nothing leaves your machine without it.
downloadDownload the AgentPoint it at your book folder
Tell the agent where your books live — a single folder is all it needs. It scans for EPUBs, PDFs, and audiobooks automatically.
Your files never move. Book Binder reads them in place, exactly where they already are.
Your library builds itself
Covers, author bios, synopses, genres, and series information are fetched automatically from public databases. No manual tagging required.
Books appear in your library within seconds, beautifully organised and ready to read.
Read in your browser
Open any book in the in-browser reader. EPUBs and PDFs render natively with four reading themes — Day, Night, Sepia, and OLED.
Your reading position is saved automatically. Close the tab and pick up exactly where you left off.
Read on any device
The first time you open a book, a private copy is saved to your personal cloud. From that point on, you can read it on your phone, tablet, or any browser — no agent needed.
Your PC doesn't need to be on. Your files are always private and only accessible to you.
Common Questions
Do my books get uploaded to Book Binder's servers?
No. A private copy is saved to your own cloud storage bucket when you first open a book. Book Binder staff cannot access your files.
What happens if I delete a book from my PC?
The cloud copy remains available. Your local library reflects the deletion on next scan, but your reading history and cloud copy are untouched.
Does the agent have to be running all the time?
Only for books you haven't opened yet. Once a book has been opened once, it's cached in your cloud and available everywhere without the agent.
Is the agent safe? What does it do on my network?
The agent only communicates with Book Binder's servers and your Supabase storage bucket. It never reaches out to third parties and never modifies your files.
