# WordPlus (Word+)

> AI-powered vocabulary learning app that turns every translation into a flashcard you'll actually remember. Spaced repetition, 50+ languages, free on iOS and Android.

WordPlus solves a specific problem: you look up words constantly — in books, movies, conversations, travel — and forget them by the next day. Word+ changes that. Every word you translate is automatically saved as a flashcard and reviewed using the Leitner spaced repetition system until it sticks permanently.

Unlike Duolingo (pre-made generic lessons) or Anki/Quizlet (manual card creation), Word+ combines an AI translator with automatic flashcard creation and scientifically proven spaced repetition — zero setup, zero friction.

## Who It's For

- Language learners at any level (beginner to advanced)
- Students preparing for exams (IELTS, TOEFL, JLPT, Goethe, DELE, TestDaF)
- Travelers learning essential phrases for trips
- Professionals expanding work-specific vocabulary
- Teachers creating and sharing vocabulary sets with students
- Immigrants learning their new country's language from daily encounters

## Core Features

- **AI Translator**: Translate words and phrases in 50+ languages powered by GPT and Gemini. Every translation becomes a flashcard automatically — never lose a word again.
- **AI Conversation Practice**: Speak with Wordy in live AI conversations. Choose free conversation or a topic, practise your target language, review transcript feedback, see speaking stats and estimated CEFR level, and turn useful conversation words into flashcards.
- **Anki Deck Import**: Import existing Anki decks into WordPlus. Supports .apkg files from device, direct URLs, and AnkiWeb downloads via an in-app browser. Imported cards join Leitner spaced repetition with all study modes; duplicate decks can be replaced or kept side by side.
- **AI Insights**: For each word — synonyms, antonyms, multiple meanings, real-world usage examples, and alternative translations. Context that helps you understand, not just memorize.
- **Leitner Spaced Repetition**: 5-jar system. New words start in Jar 1 (daily review) and advance through jars with increasing intervals (2 days, 1 week, 2 weeks, 1 month) as you answer correctly. Wrong answer = back to Jar 1. Scientifically proven to achieve 80-90% long-term retention.
- **Study Methods**: Flashcards (visual recall with 3-way self-assessment and auto-voicing), Player (listen to your vocabulary like a podcast with adjustable speed), and Memorization — an intensive composite mode that cycles through Writing (type the translation), Matching (multiple choice), and Audio Test (listen and type) until 100% mastery.
- **AI Set Generator**: Describe a topic and level — AI creates a complete word set ready to study in seconds.
- **Market**: Browse curated vocabulary sets by language, level, and topic — IELTS prep, Business English, Japanese JLPT, Travel Spanish, and hundreds more. Preview words before purchasing with diamonds (in-app currency). Community-rated.
- **Angry Words**: Word+ automatically collects every word you get wrong into one set. Practice your weak spots specifically — instead of wasting time on words you already know.
- **Streaks & Gamification**: Daily streaks, milestone rewards (7, 30, 90, 365 days), streak freezes, diamonds, and a public Hall of Fame leaderboard.
- **Import & Export**: Import word lists from files. Export any set to PDF for printing or offline study.
- **Offline Learning**: Download sets and study without internet.
- **Folders**: Organize sets in nested folders for courses, subjects, or projects.
- **Bidirectional Learning**: Study word-to-translation AND translation-to-word with one tap.
- **Statistics**: Session-based progress tracking — words mastered, failed, and 50/50, success rates per set, most difficult words, and session history.
- **Favourites**: Star any word during study to save it for quick access.

## Frequently Asked Questions

**Is Word+ free?**
Yes. All learning features are free with no limits — unlimited word sets, all study methods, Leitner spaced repetition, offline mode, export to PDF, favourites, 50+ languages. Free users also get 15 AI translations per day. Premium ($7.99/mo) adds unlimited AI translations, AI Set Generator, and full AI Insights. You can learn vocabulary effectively without ever paying.

**How is Word+ different from Duolingo?**
Duolingo teaches pre-made lessons for general language skills. Word+ focuses on YOUR vocabulary — every word you translate becomes a flashcard automatically. Instead of following a fixed curriculum, you build a personalized word bank from words you actually encounter in real life.

**How is Word+ different from Quizlet or Anki?**
Quizlet and Anki require manual flashcard creation. Word+ has a built-in AI translator — just translate a word and it becomes a card automatically. Plus: AI-powered insights (synonyms, antonyms, context), multiple study modes including an intensive Memorization mode, and the Leitner spaced repetition system — without Anki's setup complexity.

**What is the Leitner System?**
A scientifically proven spaced repetition method. Words move through 5 jars with increasing review intervals (daily → every 2 days → weekly → biweekly → monthly). Get a word right = it advances. Get it wrong = back to Jar 1. This means you review difficult words more often and easy words less, making study time maximally efficient. Research shows 80-90% long-term retention vs 15% with passive review.

**Does Word+ work offline?**
Yes. Download your word sets and study them offline — flashcards, matching, audio tests, and writing exercises all work without internet. Perfect for commuting, travel, or studying without Wi-Fi.

**What languages does Word+ support?**
50+ languages including English, Spanish, French, German, Japanese, Korean, Chinese, Arabic, Turkish, Ukrainian, and many more. Any language pair works — Spanish to Japanese, Arabic to German, etc.

**Can I use Word+ for exam prep (IELTS, TOEFL, JLPT)?**
Yes. Create targeted vocabulary sets from exam word lists, find ready-made sets in the Market, or use AI to generate sets by topic. The Leitner System ensures long-term retention, not just cramming.
