About this app

Learn Spanish, German or French by reading real stories and books. Tap a word, and SLReader tells you what it means in this very sentence, not just what a dictionary says.

TRANSLATION IN CONTEXT
The translation appears right above the word. Below it, the card shows what the word means here, its other senses, pronunciation and examples. SLReader reads the whole sentence, so it recognises phrasal verbs, idioms and constructions like “dejar de”, “anrufen” or “en train de”, where a dictionary would translate each word on its own.

READ AT YOUR LEVEL
Short graded stories from A1 to B2 in Spanish, German, French and English, with new ones every week. When you want the next step, move on to classics in the original, unabridged: Quiroga, Martí, Bécquer, Kafka, Zweig, the Brothers Grimm.

WORD SWAP
Not ready for a whole page in a new language? Start with a book in English. SLReader puts some of its words into the language you’re learning, so you meet them in the middle of sentences you already understand. Three levels, from a light sprinkle up. Tap a highlighted word to see its translation. English classics with word swap are waiting on Home: Fitzgerald, Carroll, Conan Doyle, Dickens, Wilde.

YOUR OWN BOOKS
Open your own EPUB, FB2 or TXT files. Tap to translate and word swap work just the same.

WORDS THAT STICK
Every word you look up is saved in Words, with its translation and the sentence you met it in. Flashcards bring each one back after a day, then after three days, a week and three weeks, until it sticks.

TRANSLATE A PARAGRAPH
Stuck on a whole sentence? Translate the paragraph below the text or in its place.

MADE FOR READING
Five page themes from cream to black, comfortable fonts (or your own), text size and line spacing to your taste.

Answers come in English, Spanish, Portuguese, German, French, Turkish or Russian, and the app speaks all seven.

Translations and explanations are generated by AI and can sometimes be wrong. If you spot a mistake, report it right from the card.
