why Ivy Dictionary

Look it up, then keep it

A dictionary, word books, reviews and a reader in one app — and none of it needs the internet.

Select a word, see its meaning

Select English in any app and look it up on the spot. On the computer, press a shortcut and a card appears at the top of the screen; Esc closes it.

Definitions that make sense

Chinese definitions of common words revised one by one, plus English definitions, examples, synonyms, antonyms and phrases. Misspellings are forgiven, and "went" takes you to "go".

British and American, side by side

Both phonetic spellings, and audio for the 20,000 most common words.

Word books that remember where

Saving a word keeps the sentence and where it came from; "back to the text" opens the place you were reading.

Reviews that fit your memory

Daily reviews scheduled by FSRS, so words you know come up less and less.

Read and look up as you go

Paste or open an English text and tap any word. Words above your level are marked in advance, and you can add them all to a word book at once.
