Turn vocabulary learning into a fun daily habit! VocabNinja is the free flashcard app designed for kids and students who want to master new words across any language. THREE WAYS TO LEARN Choose the mode that works best for you: - Multiple Choice – pick the correct translation from several options. Great for quick warm-ups. - Writing – type the answer yourself to strengthen recall and spelling. - Flashcards – flip cards and rate yourself. Classic and effective. Practice in both directions (A→B, B→A, or mixed) and focus on due cards with the smart filter. SMART REVIEW SCHEDULING VocabNinja uses a proven spaced repetition system based on the Leitner method. Words you know well come back less often. Words you struggle with appear more frequently. Five review levels ensure every word gets exactly the right amount of practice — no wasted time, no forgotten vocab. ORGANIZE YOUR WAY Set up as many languages as you need and structure your vocabulary in folders and boxes. Whether it is English, French, Spanish, or Mandarin — VocabNinja adapts to your school curriculum or personal goals. STAY MOTIVATED - Daily and weekly goals – set targets for vocab and lessons. - Streaks – build a learning streak and keep it going every day. - Achievements – unlock badges like "First 100", "7-Day Streak", "Perfectionist", and more. - Error rounds – missed words automatically repeat until you get them right. LISTEN AND LEARN Tap the speaker icon to hear any word pronounced out loud. Text-to-speech supports dozens of languages so you can train your ear while studying. BUILT FOR KIDS AND FAMILIES VocabNinja is simple enough for young learners and powerful enough for older students. A friendly onboarding lets kids set up their profile, choose a language, and start learning in under a minute. Optional demo data with 50 ready-made vocab items helps beginners dive in immediately. BACKUP AND TRANSFER Export your entire collection — languages, folders, boxes, vocab, and progress — to a backup file. Import it on another device or keep it as a safety copy. AVAILABLE IN YOUR LANGUAGE The app itself is localized in English, German, French, Italian, Portuguese, Polish, Chinese (Simplified), and Serbian. COMPLETELY FREE No subscriptions.

Just take a photo of any textbook page, language-app screenshot, or handwritten notes, and VocabNinja's AI import extracts the word pairs for you. Review, tweak, and drop them straight into the box of your choice — your next learning session is ready in seconds. Bring Your Own AI — Now with Three Providers Pick the AI service that works best for you, and switch any time: - OpenAI (ChatGPT) — GPT-5, GPT-5 mini, GPT-5 nano, or any model ID you like. - Claude (Anthropic) — Opus, Sonnet, and Haiku. - Microsoft Azure — connect your own Azure OpenAI / AI Foundry endpoint. Your API key is stored securely on-device and is only ever sent to the provider you chose. A clean settings card shows which provider is active, with one-tap switch, change, and delete. The model list now loads live from your provider, so new models appear automatically — or just type a custom model name yourself. Clearer When Something Goes Wrong No more cryptic "network error." If a setup or import ever fails, a new Details view tells you exactly what happened — an invalid key, an exhausted quota, or a connection problem — so you know precisely what to fix. Smoother Import Flow After a successful capture, you're taken right back to your box with a confirmation. And if you haven't set up a provider yet, the "Open Settings" shortcut now takes you straight there. Polish & Fixes - Reliable XP tracking — every correct answer counts toward your progress, every time. - Country flags display correctly across all supported languages. - Umlauts and special characters render properly everywhere in the app. - The filter pill on the Learning page now behaves as expected.
