The vocabulary builder that keeps every word you meet
Save unfamiliar words from articles, YouTube videos and PDFs, or bring in your old lists. Each word in your vocabulary builder keeps its translation, the example from the source and your current level of knowledge. Over 50 languages available.
Your vocabulary lives on the site. The extension only collects the words.
From an unfamiliar word to one you know with confidence
Everything you learn is kept in your personal vocabulary on the site: each word has a translation, an example, audio, and a knowledge level.
- 01
Add words the way that suits you
Select them on any website, in YouTube subtitles, or in a PDF, and the extension saves the word with its sentence. Type them in, import a CSV, generate topic collections with AI, or copy ready-made ones from the library.
- 02
Sort them into collections
Create collections by language, topic, difficulty, or source. Pin the ones you are working on, and filter out the words you have not learned yet.
- 03
Practice them in eight training modes
Every mode is available for any of your collections. A word’s knowledge level changes with your results or by hand, and statistics show your streak and how many words you have learned.
Collections
A vocabulary app organized the way you learn
Group words by topic, level, or source. Filter them by knowledge level, move them between collections, and pin the ones you are learning now. Progress is visible for every collection, so it is easy to pick what to review next.
Knowledge levels
Spend your time on the words you don’t know yet
Every word sits on a five-step scale from New to Known. Practice moves it, or set the level yourself, even for a whole collection at once. Filter or sort by level, and the progress bar shows how many words you know.
AI collections
Vocabulary for your goal, not someone else’s
Tell AI what you need: “IELTS writing” or “Japanese for a job interview.” Pick the level, set the number of words, and get a ready collection with translations and examples.
