The Ziokai app presents English in audio and video, with extensive explanations of the language that can be accessed at any time.
As a student of English, you get to watch and listen to real natural language, and you can stop and look at the explanation whenever you want more information about what you are hearing.
In the notes, you get a transcript and a translation of all the language explanations of the language heard there, including notes about grammar and the meanings of words.
The notes all refer to the Ziokai Manual of English, a comprehensive reference book for English learners, which is also always accessible to you.
The pages under this menu title have some samples of the explanations of selected topics of English.
Some of these notes on this demo site include the notes for Italian students of English.
