Frequently asked questions
How is this different from flashcard apps?
You learn words where they live: inside stories, with the translation one glance away. Your flashcards are made from words you chose while reading, and each one keeps its original sentence, so you review meaning in context instead of isolated words.
Which levels are there?
Every story is labeled with a CEFR level, from A1 (beginner) upward. The library currently covers A1 to C1, and AI stories can be generated at any level.
Is it free?
Yes. A free account includes 4 stories a day from the library, the side-by-side reader (tap any word to hear it), the dictionary, your Vocabulary Bank and reviews, plus 3 AI stories or imported texts a month. Paralelo Plus, with unlimited stories, more AI stories and the audio player that reads whole stories aloud, is in development.
Which languages can I learn?
Spanish and English, in both directions. More languages are planned; you can vote for the next one on this page.
Does it work offline?
Not yet. The web app needs an internet connection. Offline reading is planned for the mobile app.
How is my data used?
Only to run your account: your saved words, reviews and reading progress. We don’t sell personal data or show ads. When you ask for an AI story, only your request goes to the AI provider, never your name or email. The Privacy Policy has the details. Privacy Policy
