The problem
Reading stops when the dictionary opens.
A regular EPUB reader shows the text beautifully, but the moment you hit a word you don't know, you're copying, switching apps, and losing the thread of the sentence. By the time you find the meaning, the mood of the passage is gone.
uSage keeps the meaning inside the book. One tap and you're back to reading.
What you get
A dictionary that remembers the sentence.
Definitions are useful; context is what makes them stick.
Meaning in context
Tap a word and see the definition and translation that fit the sentence it appears in, not a generic list of meanings.
Saved with the source line
Every saved word keeps the sentence it came from, so you always remember how it felt in the story.
Spaced-repetition review
A few minutes a day brings each word back at the right time. Remembered less often, forgotten sooner.
Works offline
Download a book and read, tap, highlight and review without a signal. Sync happens when you're back online.
Free classics included
Pride and Prejudice, Frankenstein, Dracula and more are already in the library. Import your own EPUBs too.
Highlights & notes
Colour-code passages, add thoughts, and find them later by book and chapter.

Made for readers who want to grow.
Language learners
Stop switching between your book and a translation app. One tap gives you the meaning and translation of the exact word in the exact sentence.
Students & researchers

Avid readers
Even in your native language there are words worth knowing. Build a personal vocabulary passively, just by reading the books you already wanted to read.

Questions
About EPUB readers with dictionaries.
Do I need a separate dictionary app?
No. uSage has its own word lookup built in. Tap a word and you see the definition, part of speech, and a translation right there in the reader.
Does it work with any EPUB file?
Yes. You can import any EPUB you already own, or start with the free public-domain classics included in the app.
Can I use it without an internet connection?
Once a book is downloaded, reading, lookups, highlights and reviews all work offline. New books and sync require a connection.
What makes this different from a regular EPUB reader?
Most EPUB readers show the book and nothing more. uSage turns every unknown word into a flashcard tied to the sentence it came from, then brings it back for review.
