What you can read, watch and hear
Where does the content come from?
Some of it we make: guided lessons written to your level, multi-part series, and word collections. The rest is the real world. Daily news from actual publishers, podcast episodes, songs, books and anything you bring yourself.
Can I bring my own material?
Yes. Paste a link to an article or a YouTube video, upload a file, or paste raw text. It lands in your library and behaves like anything else: tappable, saveable, reviewable.
Which file types can I upload?
PDF, EPUB, plain text (.txt) and HTML (.html, .htm). EPUB is the one to prefer for books, since it keeps chapters and reflows properly at any type size.
Is anything I upload visible to other people?
No. Files you import are yours alone. Nobody else sees them and they don’t go into the shared library.
Is there audio?
Often. Podcasts come with their original audio, songs with the recording, and many lessons and series carry narration. Where a piece has audio, the sentence being spoken is highlighted as it goes, so your eyes and ears stay together. Dialogues are cast with a different voice per speaker.
How does the pronunciation above the characters work?
For Japanese you get furigana over kanji, for Mandarin pinyin over hanzi, and for Cantonese jyutping. It sits directly on top of the character rather than beside it. You can change its size, and you can have it disappear on words you’ve already learned, so the page gets cleaner as you improve.
Can I change how the text looks?
Yes. Type size, weight, line height and where the progress bar sits are all yours to set. Close a document mid-paragraph and it reopens exactly there.
