Spanish stories matched to the words you know.
Not just matched to A2 or B1. Matched to your vocabulary.
For learners with at least an advanced-beginner (A2) level of Spanish.
ReadPlusOne Tap a word to mark it unknown · Hold for sound and meaning
Sofía llega al mercado cuando el sol todavía brilla. Quiere comprar frutas para hacer una ensalada fresca.
Saluda al vendedor, Don Pedro, que siempre tiene una sonrisa. Él le recomienda mangos dulces y jugosos.
Sofía mira los colores brillantes de las frutas. Nota un pequeño detalle: el aroma de las fresas frescas que llena la junto a la entrada.
Mostly familiar words
Stories use the words you already know, so reading feels easy and enjoyable.
New vocabulary in context
A few new words appear naturally, with helpful clues right in the story.
Words return until they stick
Words you mark unknown return in later stories after increasingly longer gaps.
Three steps, then you're just reading.
Take a short quiz
Answer a few meaning-in-context questions, then tell us which verb tenses you recognize. Each answer adjusts the next question and builds your starting vocabulary.
Read a story built for you
Your story uses mostly familiar vocabulary with a small number of words ready to learn. Tap anything you don't know and keep reading.
El tren llega al andén justo a tiempo. Marta busca su asiento junto a la ventana y deja la maleta en el estante de arriba. Afuera, la ciudad empieza a moverse despacio.
Your next story learns from this one
Words you mark unknown return sooner. Words you understand move farther apart. Future stories quietly carry the review forward.
Your new words will come back in upcoming stories.
The research
Flashcards teach recall. Stories teach the word.
Flashcard apps drill words on their own. That's why a word you can recite from a card still stops you cold in a real sentence. You learned the card, not the word.
A 2025 study tested the other way round: take the words you're due to review and write them into a short story instead. Readers were then asked whether the story actually showed them what its new words meant. Stories built this way scored more than three times higher than the standard approach. It was the biggest difference the study found.
Kamzela, Lango & Dušek, "SRS-Stories: Vocabulary-constrained multilingual story generation for language learning," EMNLP 2025 (Industry Track). Word-usage rating 3.88 vs 1.24 out of 5, evaluated in English, Chinese and Polish.
The same paragraph, as the app sees it
Twenty-nine words. Twenty-six you already know, and they're what makes the other three readable.
Marta camina despacio por la acera. El aire de la mañana huele a pan recién horneado. Se detiene frente a una pequeña tienda y lee el cartel con curiosidad.
- 26 already known
- 2 due for review, back from earlier stories
- 1 new, the word this story is teaching
The Goldilocks zone
Not too easy. Not too hard. Just right.
Every reader has a band where a story is comfortable and still teaching. ReadPlusOne writes into yours.
El perro es grande. El gato es pequeño. Los dos son amigos y juegan en el jardín todos los días.
Sofía mira los colores brillantes de las frutas y nota el aroma que llena la cesta junto a la entrada.
El ayuntamiento anunció una reforma urbanística que abarca la remodelación del alcantarillado y la reubicación de comercios.
A deck you never have to open.
Tap a word you don't know and it joins your review schedule. Every time it comes due, it's already waiting inside whatever you read next, never on a card of its own.

Frequently asked questions
What level of Spanish do I need to know?
We recommend you know Spanish to at least an A2 level: the basics of grammar and a working vocabulary. ReadPlusOne is built for the gap between graded readers and real books, so complete beginners will find even the easiest stories tough going.
How does the app know what I already know?
A short quiz sets your starting vocabulary, and every word you tap or read past updates it from there.
What if the placement quiz gets my level wrong?
Every draft is checked against your vocabulary before it reaches you, and rejected if too much of it sits past your level. The system also keeps calibrating as you read: over your first stories, words you read without tapping are quietly marked as known, so a placement that came out too high or too low corrects itself quickly.
Is this only for Spanish?
Spanish is available now. More languages are planned once the model is tuned for them.
