Master English Vocabulary with AI

Add words, learn meanings, practice with exercise and master vocabulary faster.

“Flashcard apps teach you definitions. But knowing a definition isn’t knowing a word.”

Synonyms feel interchangeable

You learned "happy" and "glad" mean the same thing — but they don't. Not exactly.

Wrong word, wrong context

You know the word, but you use it in awkward or incorrect situations.

Can't use words naturally

You recognize vocabulary in reading but struggle to produce it in speech or writing.

Real depth for every word, phrase, and idiom

Definitions in English plus your native language. Multiple meanings, real example sentences, and translation toggles you control per item.

1 / 5

Meaning Memorization

A Meaning Memorization exercise asking 'What does this word mean?' for the word 'ephemeral' with its IPA pronunciation and a free-text response box.
2 / 5

Nuance Learning

3 / 5

Right Word Selection

A Right Sentence Selection exercise: 'Which sentence best demonstrates the use of ephemeral?' with three options A/B/C — only one is a natural use.
