Your library, searchable by meaning
BookMack is an intelligent library management system. Scan your shelves in minutes, ask for what you want in plain words, and always know who borrowed what.
One email when the app is out. Nothing else, ever.

Everything your library needs
Built for a shelf you actually use: easy to fill, searchable by meaning, and honest about who has what.
Ask for what you want
Ask for "a book about Nigerian history" and BookMack reads your shelf for meaning, not matching words — so it finds the right book even when the words you used appear nowhere in it.
Scan the barcode
Point your phone at the barcode and BookMack fills in the title, author, cover, and more. Keep scanning book after book to put a whole shelf in at once.
No barcode? Snap the cover
A photo of the front cover is enough: BookMack reads the title and author and finds the book.
Track what you read
Mark a book as reading or read, keep the page you are on, and see what you finished this year.
Pick your next read
Ask for something short, something long, or a book that has been waiting, and get one off your own shelf.
Share your shelf
Send someone you lend to a private link. They browse what you have and ask to borrow something; you decide. Hide anything you would rather keep off the list.
Lend with a due date
Pick who is borrowing and when it is due. They get an email, and overdue books stand out.
Friendly reminders
Send a reminder in one tap. On Premium, due-date reminders go out automatically.
Borrowers and recommendations
Keep everyone you lend to in one place, and recommend books to them by email.
Stats and activity
See what's out, what's overdue, how long loans last, and everything that happened.
Ratings and tags
Rate your books and tag them your way, then filter your shelves by tag.
Private by design
Your library is yours alone. Cover photos are read and discarded, and you can delete your account anytime.
How it works
Fill it once, then ask it anything — and never lose track of a book again.

Scan your shelves
Point your phone at a barcode and the title, author and cover fill themselves in. Keep going and a whole shelf is in.

Ask it anything
Describe the book you want and BookMack reads your own shelf for what it is about — so it finds the right one even when your words appear nowhere in it.

Lend it and forget it
Set a due date and BookMack emails the borrower, chases the book when it runs late, and tells you when it is back.
