Membra: Vocabulary Builder

Add the word you just saw. Then actually remember it. And if you want, challenge a friend to a duel.

Membra doesn’t force you to study from a ready-made word list. Add the words you hear in a show, see in an article, or write down in class. Membra brings them back when you’re starting to forget them.

NO LIMITS ON LEARNING

No energy. No lives. No daily lesson limits. Add as many words as you want, review as much as you want, and play as many duels as you want.

YOUR PERSONAL DICTIONARY

Type in a word and Membra detects the language, translates it, and places it on the correct side.

Each language pair has its own dictionary. Your English dictionary stays separate from your German one, and you can switch between them in a single gesture.

REVIEW BEFORE YOU FORGET

Membra uses spaced repetition to bring words back when you’re starting to forget them.

It doesn’t just ask whether you “knew” the answer. How quickly you respond, whether you use a hint, and the mistakes you make all affect when that word comes back.

There are four review modes: flashcards, multiple choice, typing, and mixed. If you have nothing due that day, you can keep going with free practice.

REAL-TIME WORD DUELS

Compete against another player in live 1v1 vocabulary battles.

When you attack, you choose the word your opponent has to answer. But don’t make it too easy — a fast answer can turn the advantage back against you. The match continues until a tower falls.

Can’t find an opponent? 11 different training opponents are waiting for you, each with their own personality, speed, and way of talking trash.

See a useful word during a match? Add it to your dictionary with one tap when the match ends.

EXAM PREP

Get a 600-word pack for YDS and YÖKDİL, IELTS Academic vocabulary, and English word packs from A1 to C2.

They’re all free and can be added to your dictionary with one tap.

BUILD THE HABIT

Daily streaks, streak freezes, daily and weekly missions, ranks, monthly leagues, and leaderboards.

Add friends, nudge them, send words, and compete for a higher spot.

LANGUAGES

Membra is available in English, Turkish, German, French, and Spanish.

You can also create your own personal dictionaries between these languages.

ONE HONEST NOTE

Membra is not a language course.

Instead of taking you through a fixed curriculum from A1 onward, it’s designed to help you collect the words you come across in real life and actually remember them.

If you want to learn your own words and stop forgetting them, you’re in the right place.
