How often do you use a dictionary while watching a movie, reading a book or a web article in a foreign language? Probably often. Do you recall all those words or phrases which you used a dictionary for in 1 week? Probably not. You can use many applications: dictionaries, translators, memory cards and so on to build your vocabulary. Anyway it would require some manual work to recognize different word forms, phrases and idioms. Shlang makes things easier for you, all what you need is in one place - focus on unknown words before reading/watching: Words and Phrases - mark words or phrases you already know, they will be in your vocabulary and do not bother you next time; - let Shlang know about your language (English only atm) level and Shlang will be able to not show easy (for your level personally) words; - work with unknown words or phrases: - see definitions; - see examples; - translate to any language you want/know; - if still not sure you get familiar with a word or a phrase, mark the one "to repeat" so next time you face the one Shlang will help you to recall; - repeat any of the words or phrases from your vocabulary. Media - search for movie/TV subtitles - (soon) search for books - open (with Share) - web articles, - YouTube video with subtitles, - (soon) YouTube song with lyrics. - paste any text into Shlang. Languages - advanced support for English: grouping related words, phrase verbs, (soon) idioms; - support for 180+ languages: word extraction, translation; - auto detection of text language: useful for web articles when the language is not predefined like in movies or books.
