About this dictionary

Encyclopedic Dictionary is a complete offline reference built around a database of over 66,000 entries. It is installed together with the app — no account, no subscription and no connection required.

One app for looking words up, listening to them, collecting them and learning them.

AI assistant

  • Ask AI about any word: definition & context, synonyms, pronunciation guide, example sentences
  • Word not in the dictionary? Find it with AI and add it to your own database
  • AI can write the description for the words you add yourself
  • Keep any AI answer as the word description or save it as a note

The dictionary, fully offline

  • 66,000 entries, 100% offline
  • Instant results as you type
  • Search filters: starts with, ends with
  • Voice search — just say the word
  • Search the text you copied to the clipboard
  • Alphabet index for fast browsing
  • Random word button
  • Add your own words and edit existing entries

Keep your words in order

  • Favourites — save a word with one tap
  • Bookmarks — colour-coded folders for your own topics
  • Notes — attach your own note to any word
  • History — every word you looked up, sorted by date, name or view count
  • Multi-select mode: export, listen to, bookmark or delete many words at once
  • Export your word lists to a text file and share them

Practise and memorise

  • Flashcards — the classic way to memorise new vocabulary
  • Quiz — multiple choice test on your own words
  • Listening — hear the word and choose the right answer
  • Word game — guess the hidden word in 4 to 7 letters, with statistics and win streaks
  • Build your own training sets: pick the source, the number of words, the order and the difficulty
  • Start a training session straight from your favourites, bookmarks or history
  • See what you got right and repeat only the words you missed

Pronunciation (text to speech)

  • Listen to the word and to its full description
  • Clear pronunciation for every entry
  • The built-in player reads whole word lists at 0.5x, 1x or 2x speed
  • Playback continues with the screen off

Backup and sync

  • Back up your favourites, bookmarks, notes, history and your own words
  • Save to the cloud with your Google account, to a local file, or to Dropbox
  • Restore everything on a new device in seconds

Daily word notifications

  • Receive a word as a notification during the day
  • Choose the time, the weekdays and the source: random, favourites, bookmarks or history

Learn from the home screen

  • Word of the day widget
  • Word list widget
  • Training widget — learn without even opening the app

Set it up your way

  • Dark mode and automatic night mode
  • Adjustable text size and interface colour
  • Show, hide and reorder the tabs — keep only what you use
  • Interface available in English, Русский, Español, Italiano, Deutsch, Français, Türkçe, Azərbaycan, Українська
  • Select text in any other app to search it here or add it to your dictionary
  • Full tablet and landscape support

It works as Encyclopedic Dictionary, as an offline reference without internet, as a vocabulary builder and as a word learning app.

This is an offline dictionary — the database is kept on your device, so it needs some storage space.
