Vocab Feed is a free AI vocabulary app designed to help you learn new words online — fast. It uses artificial intelligence to generate unique vocabulary flashcards with a TikTok-style swipe interface, helping you build vocabulary effectively in over 30 languages. Whether you want to learn German vocabulary, master Spanish words, or expand your Japanese word bank, Vocab Feed adapts to your level and goals.
Vocabulary cards are generated in real time by a large language model. Unlike traditional flashcard apps that rely on pre-made word lists, Vocab Feed creates fresh, unique content every session. Each card includes the target word, its English translation, native-quality pronunciation audio, natural example sentences showing the word in context, a CEFR difficulty level from A1 (beginner) to C2 (mastery), and helpful usage notes.
The learning interface is simple and intuitive. You swipe up to see the next vocabulary card, tap the heart button to save favorites for later review, and tap the skip button on words you already know. Skipped words are permanently remembered — they will never appear again, so your feed stays fresh and challenging.
What makes Vocab Feed different from other vocabulary apps is its AI backbone. The app connects to a cloud-based language model that generates vocabulary cards on demand. This means you are never limited to a fixed database of words. The AI tracks every word you have already seen in your current session and combines that with your permanently skipped words to ensure zero repetition. The result is an infinite stream of new vocabulary tailored to your chosen language and difficulty level.
Each vocabulary card is more than just a word and translation. The AI provides contextual example sentences that show how native speakers actually use the word, pronunciation guidance, frequency hints telling you how common the word is, and topic tags that organize vocabulary by themes like food, travel, business, or emotions.
Vocab Feed supports vocabulary learning in over 30 languages. The most popular options include German, Spanish, French, Italian, Portuguese, Japanese, Korean, and Chinese. But the app also covers less common languages like Azerbaijani, Croatian, Slovak, Malay, Hebrew, Finnish, and many more. You can switch your target language anytime in the settings — no need to create a new account or start over.
Every language uses the same powerful AI engine, so you get the same high-quality vocabulary cards regardless of which language you choose. Cards include script-appropriate content: Cyrillic for Russian and Ukrainian, Devanagari for Hindi, kanji and hiragana for Japanese, Hangul for Korean, and traditional or simplified characters for Chinese.
Every card is generated fresh by AI. No static word lists — your vocabulary content is always new and never repetitive.
Full-screen cards you swipe through vertically. Fast, engaging, and designed to make vocabulary practice feel effortless.
Hear every word spoken with high-quality text-to-speech audio. Build listening and pronunciation skills from your first session.
Choose from A1 (beginner) through C2 (mastery). The AI generates vocabulary matched to your proficiency so you learn at the right pace.
Heart words you want to review later. Skip words you already know and they permanently disappear from your feed.
