How many books do you have at home? And your friends... do you have any idea what's on their shelves?

We buy books that are already sitting around us. We look for recommendations on apps that track us... when the best advice is just next door.

BiblioGenius changes that.

How it works

Scan a barcode: cover, summary, everything appears from BNF, Inventaire, OpenLibrary. In a few minutes, your library takes shape. Selections, shelves, reading tracker. And everything stays on your phone - your data never passes through any server.

Your friend also has BiblioGenius? Scan her QR code and her library appears on your screen. That novel you've been looking for? It was ten meters away. You request a loan, she accepts. Everything is end-to-end encrypted - even the relay server can't read your exchanges.

What's inside

  • Smart scanning: barcode, mass scan, automatic enrichment from 5 sources (BNF, SUDOC, Inventaire, OpenLibrary, Google Books)
  • Encrypted sharing: on the same WiFi or remotely via the relay hub, everything is end-to-end encrypted
  • Audiobooks: search and listen from LibriVox, Archive.org and LittératureAudio
  • Gamification: badges, streaks, reading goals, leaderboard with friends
  • Mini-games: puzzle and memory using your library's book covers
  • Import: Goodreads, Babelio, LibraryThing, Gleeph, ISBN list
  • 5 platforms: Android, iOS, macOS, Windows, Linux

Why test now?

The app is in beta. Every piece of feedback matters: a bug spotted, an idea, a friction in the interface. By testing now, you shape the project from the start.

It's free, open source (AGPL-3.0), and built by an independent developer. The code is auditable by anyone.

Join the beta
