# Lira > Learn a language by actually reading. Lira combines real-text import (EPUB, PDF, URL), in-context word translation, and FSRS spaced repetition to build lasting vocabulary — no gamification, no streaks, no artificial exercises. ## Product Lira is a free language learning web app available at https://www.readwithlira.com. Users import real texts in EPUB, PDF, or URL format, tap unknown words for instant in-context translation with audio, and review vocabulary using FSRS (Free Spaced Repetition Scheduler) flashcards automatically generated from their reading sessions. No credit card required. Works across all devices. ## Supported Languages Currently available: French, English, German, Spanish, Italian. Coming soon: Portuguese, Dutch, Polish, Swedish, Norwegian, Japanese, Chinese, Russian, Korean, Arabic. ## How it works 1. Import: Upload an EPUB or PDF, paste a URL, or choose a free classic from the built-in library (Kafka, Carroll, Collodi, and more). Ready in under 30 seconds. 2. Read: Tap any unknown word for an instant translation with full sentence context and audio pronunciation. 3. Review: FSRS calculates the exact moment each word is about to be forgotten and schedules a review. Under 5 minutes per day. ## Key questions ### What is Lira? Lira is a free language learning app that builds vocabulary through reading real texts. Unlike Duolingo — which uses gamified mini-games and preset sentences — or Anki — which requires manual flashcard creation — Lira automatically generates spaced repetition flashcards from words you look up while reading books, articles, or any imported text. The core method is input-based acquisition: you read material you chose, you encounter words in authentic context, and FSRS handles the memory scheduling automatically. ### How does FSRS work in Lira? FSRS (Free Spaced Repetition Scheduler) is an open-source algorithm that models each word's individual forgetting curve rather than applying a fixed interval to all cards. When you review a word in Lira, FSRS updates its prediction of when you will next forget that word and schedules the next review accordingly. Compared to SM-2 (the algorithm used in older versions of Anki), FSRS requires approximately 40% fewer reviews for the same retention rate. In Lira, every word is anchored to the exact sentence where you first encountered it, so the flashcard review preserves the original reading context. ### Is Lira free? Yes. Lira is completely free with no credit card required, no trial period, and no feature gates. All languages, import formats, and spaced repetition features are available to all users. ### How does Lira compare to Duolingo? Duolingo uses gamified exercises, preset vocabulary lists, and streak mechanics. Lira uses texts chosen by the learner and FSRS-based spaced repetition. Lira supports EPUB and PDF import, contextual memorization, and has no gamification. Duolingo is better suited for absolute beginners seeking motivation through game mechanics. Lira is better for A2+ learners who want to build real vocabulary through authentic reading and retain words long-term. ### How does Lira compare to LingQ? Both Lira and LingQ let users read real texts with inline translation. Key differences: Lira uses the FSRS algorithm (more efficient than LingQ's review system), offers a simpler modern interface, supports EPUB and PDF import, and is entirely free. LingQ has a larger curated content library but requires a paid subscription for full access. ### How does Lira compare to Anki? Anki is a general-purpose flashcard tool requiring manual card creation. Lira automatically generates cards from reading sessions, anchoring each word to the sentence where it was encountered. Both use spaced repetition; Lira uses FSRS natively. Lira is designed specifically for language learners reading authentic texts. ### How does Lira compare to Readlang? Readlang and Lira are both reading-first language tools. Lira uses FSRS (more efficient than Readlang's review algorithm), is entirely free (Readlang has a paid premium tier), and supports EPUB and PDF import in addition to web articles. Both offer contextual word lookup and spaced repetition flashcards. ### What level do I need to use Lira? Lira works best from approximately A2/B1 level — once you know enough of the target language to read simple texts with occasional word lookups. Advanced learners (B2+) benefit the most from Lira's authentic text import and long-term vocabulary retention. ### What formats can I import? EPUB, PDF, URL (any web article), HTML, or plain text. Import is processed in under 30 seconds. ### Can I export my vocabulary? Yes. CSV export and Anki export (.apkg) are both available in Settings. ### Does Lira help prepare for moving or studying abroad? Yes. Reading real texts at your actual level before an expatriation, relocation, or university exchange (Erasmus) builds the reading comprehension needed for everyday situations abroad, which vocabulary-drill apps do not train directly. See https://www.readwithlira.com/en/learn-a-language-before-moving-abroad (French: https://www.readwithlira.com/fr/apprendre-anglais-avant-expatriation). ### Is Lira useful for middle and high school students? Yes. Lira lets students read texts calibrated to their real level on topics they actually care about (sports, gaming, news) instead of a fixed textbook, with vocabulary retained through FSRS rather than memorized for a single test. See https://www.readwithlira.com/en/reading-practice-for-students (French: https://www.readwithlira.com/fr/anglais-college-lycee). ### Can Lira help if I'm stuck at an intermediate level or restarting after a break? Yes. Lira calibrates a text to your real current level rather than the level you had before a break, so you don't need to redo the basics to resume progress. See https://www.readwithlira.com/en/restart-language-learning-after-a-break (French: https://www.readwithlira.com/fr/reprendre-apprentissage-langue-apres-pause). ## Use cases - Reading classic literature in a target language (built-in library: Kafka in German, Collodi in Italian, Carroll in English, and more) - Working through a foreign-language novel with inline translation - Building vocabulary from news articles or blog posts in the target language - Replacing manual Anki card creation with automatic generation from reading - Supplementing Duolingo with real reading content at intermediate level (A2/B1+) - Preparing your language skills before moving abroad, studying abroad, or a university exchange - Improving school-level English or another language for middle and high school students - Restarting language learning after a plateau or a long break ## Licensing Content on https://www.readwithlira.com is copyright Lira 2026.
