ViDic
Read full descriptionHide full description
ViDic turns vocabulary learning into something you actually remember โ because you learn with your eyes, not just your ears. Most people forget new words within a day. ViDic fixes that with a simple idea: pair every word with an image, and your memory does the rest. WHY ViDic WORKS โข Image-first learning Every word comes with a picture that captures its meaning at a glance. No more translating in your head โ you just see it and know it. โข The 1-3-5 study method Backed by the forgetting curve, ViDic automatically brings words back to you on day 1, day 3, and day 5 โ right when you're about to forget them. That's what makes new words stick for good. โข Daily study words Every word you look up is organized by the day you learned it, so you can review exactly what you studied and when. โข AI conversation tutor Practice speaking with an AI tutor that builds real conversations around the words you just learned โ not flashcard drills, actual dialogue. โข Image quiz Test yourself by matching words to images under a timer โ a fast, fun way to check what's really sticking. โข Your own wordbook Save words into folders, track what you've mastered and what still needs review, and build a personal vocabulary library over time. โข Learn in your language Full support for 15 interface languages, so you can study any target language in the language you're most comfortable with. Whether you're studying for travel, work, an exam, or just for fun, ViDic makes vocabulary something you actually remember โ not just something you looked up once. Download ViDic and start remembering with your eyes.
