About this game

How well do you know your favorite book? Word by Word turns any book into a game: the text appears word by word, and you guess what comes next.

Pick a phrase to start from — or the beginning of a chapter — and keep going. For every next word you get a few options: one is the author's, the others are plausible traps picked by an AI model. Guess right and the story moves on. Guess wrong and you lose a life. How far can you get with five?

★ PLAY WITH YOUR OWN BOOKS
Open EPUB, FB2 and MOBI files from your device. Uncheck the parts that aren't the story — table of contents, notes, imprint — and save the book to your library so it's ready to play next time.

★ THOUSANDS OF FREE CLASSICS
Download public-domain books right in the app from Project Gutenberg and Wikisource: Austen, Dickens, Tolstoy, Shelley, Melville, Carroll and many more, in dozens of languages.

★ SMART TRAPS, ON YOUR DEVICE
The word options are suggested by Gemma 3, a compact open language model by Google, running right on your phone. It is downloaded once (about 290 MB) and then works offline — your books never leave your device.

★ THREE DIFFICULTY LEVELS
Choose between two, three or four word options. Easy for a relaxed read, Hard when you really know the text.

★ MADE FOR READERS
• Classic book typography with chapters, italics and paragraphs
• Start anywhere: a random phrase or the start of any chapter
• Skip a paragraph that isn't part of the story
• Your library remembers each book's chapter selection

★ NO ACCOUNTS, NO ADS
No sign-up, no ads, no tracking. Just you and the book.

Interface languages: English, Deutsch, Español, Français, Italiano, Polski, Português, Türkçe, Русский, Українська.

Note: Word by Word is not affiliated with Project Gutenberg or the Wikimedia Foundation. Books from these libraries are free and in the public domain or under free licenses.
Guess the next word of your favorite book. A word game for readers.

What’s new

What's new:
• Easy mode is more forgiving: each mistake now costs half a heart, so you get 10 lives instead of 5.
• Library search polish: the placeholder text is now dimmed, and the clear button only appears when there's something to clear.
