ShelfKeeper: ISBN Book Scanner

Most book tracking apps have forgotten what reading is actually about. They treat your private library like a social media feed, pressure you with gamified 50-book annual streaks, flood your screen with sponsored shopping links, and reduce your reading life to performative metrics. Reading should be all about.. reading.

ShelfKeeper is built on a different principle: quiet utility.
It is a fast, offline-first home library catalog designed for real readers, physical book collectors, and home librarians. No social algorithms, no performative reading streaks, no sponsored ads—just a dependable, private tool to organize, search, and appreciate the physical books on your shelves.

• Lightning-Fast Offline ISBN Scanner
Point your camera at the barcode on the back of any book to log it in less than a second. Powered by an on-device scanner engine, it works entirely offline with zero latency—ideal for basement stacks, remote cabins, or used bookshops with no reception.

• Smart Store Mode & Duplicate Checker
Standing in a thrift shop or bookstore wondering if you already own a title? Open Store Mode to search or scan on the spot. ShelfKeeper’s smart title matching checks for alternate editions, subtitles, and prints so you never buy an accidental duplicate again.

• The "Digital Shelfie" Virtual Bookshelf
Move past boring spreadsheets. View your collection as a customizable virtual wooden bookshelf displaying high-resolution cover artwork. Choose from rich wood finishes (Walnut, Oak, Mahogany, Pine, Cherry, Ebony), custom aesthetic backdrops, and spine or cover views.

• 1-Tap Text & Clipboard Import
Spot an intriguing title in an article, a message from a friend, or on social media? Share the text straight to ShelfKeeper or simply copy the title to your clipboard. When you open the app, it automatically recognizes the book and stages it in your basket.

• Global Omnibar & Wishlist Tracker
Heard a book recommendation on a podcast? Use the universal omnibar to search across millions of titles and save it to your wishlist in a single keystroke before you forget.

• Lending & Borrowing Manager
Never lose track of where your books went. Mark books as borrowed from your local public library.

• Complete Data Sovereignty (CSV Import & Export)
Your data belongs to you—always. Export your entire catalog to a clean CSV file with one tap anytime. Import existing libraries from Goodreads, StoryGraph, Calibre, or custom spreadsheets with ease.


ShelfKeeper Pro gives you powerful features to maintain your library while also supporting a Indie solo developer studio.

• Smart Scan (Front-Cover OCR Recognition)
Have vintage editions, antique volumes, or indie prints without an ISBN barcode? Smart Scan uses multimodal AI to identify books directly from their front cover artwork and typography.

• Automated Library Cleanup & Metadata Healer
Tired of community book databases with missing covers, typos, or incomplete author fields? Library Cleanup audits your catalog, fixes missing details, autocompletes records, and pulls crisp cover art automatically.

• Household Cloud Sync & Family Library
Keep shared home collections in sync across everyone’s devices. Family members can browse the household inventory, avoid buying duplicates, and optionally share personal wishlists.
