How it works

Three simple steps to a vocabulary that sticks.

Save any word you come across while reading.

2

Understand

See a clear definition and an example sentence instantly.

3

Remember

Review at increasing intervals so each word stays with you.

Backed by science

Built on spaced repetition — the proven memory technique popularised by tools like Anki — to move words into your long-term memory instead of cramming and forgetting.

“The limits of my language mean the limits of my world.”
— Ludwig Wittgenstein
