Find it. Read or listen. Pass it on to the next reader. And read it together, without spoilers.

Contact supportThese capabilities are in the current version of the app. Availability can still depend on your account and device.
Search the full catalog, scan a barcode, or add a book by hand. Whatever you’re looking for, it takes seconds.
The reader is the heart of the app. Open the formats you actually have — books, documents, comics, data files — and read them the way you like.
A local-first library that works offline and keeps your reading life in sync. Your notes and progress follow you from phone to phone.
Paper books: sell, exchange, gift or lend them straight to another reader. Each request has a real order or handover flow; SecondBook does not hold the payment.
A reader, an audio player, a way to pass paper books on, a book club, and a storefront for authors and shops. A book’s life is usually scattered across separate services; here it stays on one path — and none of it is paid for.
Each of these does one job well. We do the joins between them.
The book is already in the catalogue.
find it nearby · buy · swap · receive as a gift · add your own · say which format and language you are waiting for
However suits you.
paper · e-book · audio · the page follows you between devices
The club gathers around the book, not around one file.
nominate · vote · shared progress · discussion opens as you read · meet up and split into small groups for coffee
The last page is not the end of the book.
sell · swap · gift · lend · hand it to the next reader in the club
Three kinds of people use this, and none of them pay.
Everything you normally pay for in pieces.
Your own readers, not a place in somebody’s ranking.
A storefront and orders without building an app.
And the parts that should stay invisible.
AI holds the first line around the clock and a human steps in when a human is needed — not a ticket that waits for Monday.
Listings are checked before they are published, and messages in private and club chats before anyone else in the chat sees them.
SecondBook holds no payments and takes no cut: the buyer and the seller settle directly.
Your files, your progress and your library belong to you, and the account — with everything in it — is deleted by your own button.
Everything above is free. Not a trial and not «free for now»: SecondBook has no paid plan.
One book. One unbroken path.
A club picks its book by vote, everyone records their own progress, and a discussion opens only for readers who have reached that chapter. Then the club keeps going: it schedules a meeting, breaks into small groups over coffee, and passes the paper copy to the next member. A club can be open to everyone — an open one is joined with a single tap — reachable by link with a request, or invite-only.
SecondBook gives your library a read-only valuation — a simple view of what your collection is worth. It’s your books as an asset, nothing more.
No wallet, no deposits, no withdrawals — valuation only.
In-app help and support backed by an AI assistant. It analyses and proposes — a human always stays in control.
