How StoryFluent works
A closer look at the reading experience, and the features that quietly build your vocabulary while you're just enjoying the story.
Built around your reading
Every feature starts from the book in your hands, not a separate curriculum.
12 languages, any pair
Read in any supported language and learn any other, in whichever direction you need.
Yours, on your device
No account, no cloud, no subscription. Your books and your progress stay on your phone.
Watch your book become a new language
Import any book you already own, or pick one up from the Store, and watch StoryFluent quietly swap in your target language as you read. No jarring switch, just a steady shift that grows the deeper you get into the story.
- Word swaps happen right on the page as you read, not in a separate study mode
- Read in any of 12 languages and learn any other, from Spanish to Arabic
- Works with any book you import, or a title from our Store

It gets richer exactly when you're ready
There's no dial to fuss with. StoryFluent quietly turns up the immersion as you get deeper into a book, and you're always in control of how far it goes. Want it more focused? Point it toward the words and topics that matter most to you.
- Immersion builds automatically the further you read into a book
- Dial the overall intensity up or down, anytime
- Focus on a theme, or the kinds of words you want to prioritize
Never lose your spot looking up a word
See a word you don't know? Hold the page to see what it means, instantly, no searching, no leaving your spot in the story. Want more? Tap through for the full picture: definition, example, and how it sounds.
- Instant meanings for every translated word on the page
- Tap through for a full definition, example, and pronunciation
- Words you look up are automatically saved for later
The rain had not stopped since morning, and the streets below glimmered like rivers of glass. She pulled her coat tighter and hurried past the shuttered shops, her footsteps echoing in the empty square. Somewhere ahead, a bell began to ring. She quickened her pace, counting the doorways as she passed, until a familiar window came into view, glowing warm against the gray evening. Whatever waited on the other side of that door, it could not be worse than the cold. The old door groaned as she pushed it open, and for a moment the warmth of the room wrapped around her like a blanket. A fire crackled in the hearth, and the smell of coffee and old paper filled the air. He looked up from his book the moment she stepped inside, as though he had known exactly when she would arrive. Neither of them spoke. There was no need to, not yet. She simply crossed the room, sat down across from him, and let the silence settle comfortably between them, the rain still tapping softly against the window glass.
Hear the book, in two languages at once
Tap play and StoryFluent reads the book aloud, narrating in your language and speaking every swapped word in your target language, exactly as it appears on the page. The page follows along, so you can read, listen, or both.
- Narration stays in sync with the page you're reading
- Swapped words are pronounced in your target language, right where they appear
- Works with the books you import as well as the ones you buy

A quick review keeps words from slipping away
Every word you save gets quietly brought back right when you're about to forget it. A few minutes of quick review is enough to make it stick, for good.
- Reviews are timed to when you're about to forget, not on a fixed schedule
- Fast, bite-sized quiz rounds
- Anything you miss comes right back around
Learn words before you even meet them in a book
Not every word has to come from a page. Work through short, focused lessons anytime, and the words you learn show up first the next time you open a book.
- Short lessons with audio and real example sentences
- Quick quizzes so words really stick
- Newly learned words show up first in your next reading session
Play your way through the words you're learning
Word Ladder, Word Search and Fill the Blank all draw on the words you've actually met in your books. Each has five levels that get sharper as you improve, so a few minutes on the bus turns into real practice.
- Three word games, each with five levels to climb
- Built from the words in your own reading, not a generic list
- Best scores and a daily practice goal to keep you honest

Learn to write every script, one stroke at a time
Some languages are as much about shape as sound. StoryFluent's chalkboard teaches you to write, whether that's Hangul, kanji, hanzi, Cyrillic, Devanagari, Arabic or an accented Latin alphabet, scoring your strokes as you draw them. Then quick memory and speed games make sure the shapes stick.
- Every one of the 12 languages, from Korean and Japanese to Arabic and Hindi
- Trace mode scores your strokes; memory and speed games lock them in
- Levels that climb as your writing improves
Keep learning with today's headlines
Between books, read the news instead. Stories from Global Voices, the BBC, Le Monde, Die Zeit and dozens of other outlets arrive in your language with the same gentle word swaps, so every day brings fresh vocabulary.
- Filter by topic, region or source, or add your own city for local news
- Save stories for later, or read a short version when you're pressed for time
- Every article gets the same word swaps and tap-to-learn as your books
Every word you've learned, organized for you
Everything StoryFluent teaches you lands in one place automatically, sorted the way you actually think about language: by topic, and by how well you know it. Watching it fill up is oddly satisfying.
- Browse by everyday topic, from food to travel to emotions
- See what you've mastered, and what still needs work
- Turn off any word you'd rather not see swapped into your books
Streaks, stats, and a wall of badges that keeps growing
Your Profile tracks your progress and keeps you coming back, with a daily practice goal, levels to climb and badges to unlock along the way. Keep it up long enough, and you'll even earn free books for your library.
- Track your streak, and watch your personal best grow
- Unlock badges as you hit new milestones
- Level up to earn free books, or invite a friend and you both get one
A shelf that's entirely yours
Every book you own lives on one shelf, organized like a real bookshelf, not a bare list. Pick up where you left off with one tap, keep a few going at once, favorite what you love, and switch your target language right from here.
- Import any EPUB, PDF or text file you own, from Tolkien to your favorite BookTok pick
- Keep several books in progress at once
- Switch your target language right from the Library screen
