AI Vocabulary Builder

AI Vocabulary Builder helps you learn languages with personalized, AI-powered vocabulary lists and practical language tools.

AI Vocabulary Builder is free to download. Optional Pro and Premium auto-renewable subscriptions are available as in-app purchases.

SET YOUR LEARNING PROFILE (advanced levels and extra translation languages may require a subscription)
Choose the language you’re learning, the languages you already know, and your CEFR level. The app uses your profile so lists and tools match your goals.

GENERATE VOCABULARY LISTS (subscription may be required for extended AI use)
Describe a topic—travel, work, food, or anything else—and let AI create a vocabulary list tailored to you. Open a list to browse definitions, translations, phonetics, and example sentences.

STUDY WITH LEARNING CARDS
Flip cards to test yourself. Swipe right if you know a word, or left to see it again. Build confidence through focused practice.

GROW YOUR LISTS (AI expansion may require a subscription)
Expand a list with AI when you want more words, or add terms yourself whenever you need extra practice.

LANGUAGE TOOLS (may require a subscription)
• Idioms — explain an idiom or discover idioms for a topic or situation
• Name etymology — explore the origin and meaning of a name, broken into parts with translations
• False friends — spot words that look familiar across languages but mean something different
• Cognates — find related words in languages you know, and watch out for false cognates
• Pronunciation — get phonetic spelling, tips, and rhyming words

Built for learners who want more than a dictionary. Available in many app languages on iPhone and iPad.

SUBSCRIPTIONS AND IN-APP PURCHASES
Free access includes creating vocabulary lists manually, studying with learning cards, and limited use of AI features. Extended or unlimited access to AI vocabulary generation, AI list expansion, language tools (idioms, name etymology, false friends, cognates, pronunciation), advanced CEFR levels, additional translation languages, select language packs, multiple learning profiles, and backup export/import may require a Pro or Premium subscription (in-app purchase).

Payment is charged to your Apple ID account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel subscriptions in Apple ID Account Settings.
