VocabAI: AI Vocabulary Builder

Master vocabulary with VocabAI – a gamified language learning app that turns flashcards, quizzes, and spaced repetition into a daily habit.

VocabAI 2.0 is the vocabulary app that actually makes words stick — with AI-powered flashcards, four mini-games, spaced repetition science, and a daily Brain Score that shows your real progress.

Whether you're preparing for IELTS, TOEFL, or GRE, learning Spanish, French, German, Dutch, Italian, or Farsi for life, or simply building a stronger vocabulary every day, VocabAI adapts to your level and keeps you coming back.

HOW IT WORKS
Swipe through your daily word feed. Each card gives you the word, its translation, example sentences, pronunciation, grammar context, synonyms, and real-life idioms. Mark, it learned, skip it, or quiz yourself — all in one flow. The AI learns from every tap.

LEARN SMARTER, NOT HARDER
• Daily word feed based on your language, level (A1–C2), and topics you care about (Travel, Business, Daily Life, and more).
• Flashcard flow: see the word, reveal the meaning, mark learned or skip, then reinforce it with quick inline quizzes.
• Practice sessions: 10‑question multiple‑choice drills using only words from your learned pool, with XP for correct answers and bonuses for perfect or fast runs.
• Spaced repetition: a simplified SM‑2 algorithm schedules each review so words reappear just before you forget them, adapting to your performance over time.

BUILT FOR REAL-WORLD LANGUAGE USE
• Multi‑language support so you can build vocabulary in English, German, French, Spanish, Italian, Dutch, or Persian (Farsi).
• Example sentences and grammar context help you understand how each word is used in natural speech and writing.
• Optional AI‑generated examples and synonyms give you nuanced meanings and related vocabulary to expand your range.
• Day mode lets you revisit any previous day and quickly browse what you learned.

STAY MOTIVATED WITH STREAKS AND XP
• Streaks: your  user_streaks  progress updates automatically on activity and rewards you for coming back every day.
• XP system: earn points for every action—learning cards, answering quizzes, completing practice sessions, and playing with speed bonuses.
• Streak multipliers boost all XP (up to 2x for long streaks), helping committed learners unlock levels faster.
• Track your daily progress at a glance with streak and XP in the top bar so you always know how you’re doing.

PERSONALIZED TO HOW YOU LEARN
• Custom & Public Collections: Group words your way! Create your own custom collections to save specific words for later study, or explore public word collections curated for quick learning
• Choose your learning language and level, then refine it further with topic selection (e.g., Travel, Work, Food, Exams).
• Multiple languages so you can navigate the app comfortably while learning another language.

PRACTICE, REMEMBER, AND REVIEW ON YOUR SCHEDULE
• Word loading pipeline prioritizes words due for review, then introduces new ones in small daily batches so you never feel overwhelmed.
• Offline‑friendly: words for the day are cached on your device so you can keep learning even with a poor connection.
• Dedicated practice screen for focused quiz sessions when you want a quick, intense review.
• Optional notifications and reminders to keep your streak alive without being intrusive.
