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.
Your book, slowly becoming a new language
Pick any book from the library and set how much of it you want translated. StoryFluent swaps a percentage of words into your target language right in the text — starting small and increasing as you get more comfortable.
- Adjustable replacement slider, from a few words to whole sentences
- Smart suggestions to increase difficulty once you've mastered what's on the page
- Beginner, intermediate, and advanced word tiers you can toggle on or off
with translated words
Never lose your place looking up a word
See a word you don't recognize? Long-press the page and StoryFluent instantly shows you every translated word currently on screen, along with its meaning — no flipping to a separate dictionary app.
- Instant definitions without leaving the page
- Tap through to a full word popup for extra detail
- Words you look up are tracked automatically for spaced review

Every word you've learned, organized for you
Every word you encounter is saved to your personal dictionary with a progress bar that fills up as you review it. Filter by difficulty tier or by theme — food, travel, emotions, and more — to focus your practice.
- Confidence bar per word, based on both review and passive reading
- Ten thematic word categories to browse by topic
- Spaced repetition keeps older words fresh
