Aidic: AI Vocabulary Builder

Aidic turns every word you meet into one you keep. Look it up, let AI explain it properly, and the app schedules exactly when you should see it again.

Smart word lookup
Type any word and get a full explanation: pronunciation (IPA), meanings in your own language, collocations, synonyms, natural example sentences and common mistakes. Every word you save goes straight into your library.

Spaced repetition that adapts to you
Reviews follow the SM-2 algorithm. Words you know well come back less often; words you struggle with come back sooner. A short daily session keeps your whole vocabulary fresh.

Quizzes in several formats
Fill in the blank, translate, pick the right meaning and build your own sentence. Questions are made from your own words and their real collocations and examples.

Stories, reading and podcasts from your words
Ask the AI for a short story, a reading passage or a podcast episode built around the words you are learning, so you meet them again in context.

Listen hands-free
Turn your word list into an audio playlist and keep learning on a walk or a commute, with quick, normal and deep listening modes.

See how words connect
A word graph links each word to its synonyms, collocations and easily confused neighbours. Confusion sets help you finally tell similar words apart.

Stay motivated
Daily goals, streaks, XP, levels, a growing vocabulary forest, more than twenty achievements, a weekly report and a home-screen widget.

Learn in your language
The app and its explanations are available in 26 languages, and you choose the language you are studying.

AI access
Sign in with Google to use AI managed by the app, with no setup. Advanced users can instead connect their own OpenAI, Anthropic or Google AI key.

Plans
A new account starts with a free trial of the managed AI. Aidic Pro is available as a monthly or yearly subscription, or as a one-time lifetime purchase, each with its own monthly AI allowance shown in the app. Subscriptions renew automatically until you cancel them in Google Play subscriptions. Everything you have saved stays on your device whatever plan you are on.

Privacy
Your words, reviews and progress are stored on your device. When you use an AI feature, the text of that request (and the audio, for voice features) is sent to the AI provider that answers it: OpenAI, Anthropic or Google. Sign-in, purchase verification and app integrity checks use Google Firebase. No advertising.
