Your to-be-read pile, finally organized

My Tsundoku sorts your book collection into four clear piles. Free, offline-first, no account required.

A book tracker shaped like your shelves

Four piles: wishlist, tsundoku (the to-be-read pile), library, to sell. Drag books from pile to pile as your reading life moves on.

Add a book in seconds

Scan the ISBN barcode and the details fill themselves in — title, author, cover, via Open Library. Or type everything in manually if you prefer.

Your data stays with you

Everything is stored on your device and works offline. Install it on your phone like a native app. A simple alternative to Goodreads for tracking what you own and what you'll read next. Cross-device sync exists, but it's optional.

Free and open source

My Tsundoku is free software (AGPL), with no ads and no tracking. Organizing your library shouldn't cost anything.
