HOW TO USE THE INTERFACE
​
​
​
​
​
​
​
​
​
​
​
​
​
​
​
​
​
​
To get started, create a name for your profile. If you like, you can add a profile picture!
​
​
​
​
​
​
​
​
The first screen you’ll see is the Library page. You should click the icon in the middle of the page to add your first file. Scroll-io only supports .txt files at this time. If you have the wrong kind of file, like a .docx, .epub, .mobi, or something else, you can always use an online file converter. We recommend Cloud Convert.
​
​
​
​
​
​
​
​

Once you’ve added a file to your Library, you can open it. This is where the real magic happens!
THE WORD LIST
​
​
​
​
​
​
​
​
​
​
​
​​
​
​
​
​
On the left, you’ll see the word list. It displays every word used in the file, as well as how often each word appears in the document. You can use it to see how common each word is, so you can better decide which words are most important for you to learn.
​
​
​
​
​
​
​
​
​
​
​
​
​
You can choose to show All words, only words that you know, or only words that you don’t know. In this example, the user hasn’t marked any words as “known” yet, so nothing shows up in the Known list.
​
​
​
​
​
​
​
​
You can click “Word” or “Instances” to sort the word list alphabetically, or by frequency. Here, you can see that the most frequent word in the book is “the.”
HOW DO I TELL THE PROGRAM WHICH WORDS I’VE LEARNED
There are a few different ways you can mark words as “known” or “unknown.”
​
​
​
​
​
​
​
​
​
​
​
​
​​
​
​
You can click the checkbox next to any word in the Word List.
​
​
​
​
​
​
​
​
​
​
​
​
​
You can left-click on words in the text display.
You can right-click and drag to mark large sections of text all at once.
​
You can use the check box at the top of the Word List to mark everything in the document as “known” or “unknown” at once. Be patient, this may take a while, especially with large documents.
​
​
​
​
​
​
​
​
​
​
You can see a breakdown of important numbers and statistics in this box at the bottom of the screen. “Total words” tells you how many words are in the document, while “Unique words” tells you how many different words are in the document. For example, in the screenshot above, the word “prince” shows up 1,960 times. The “total words” section counts that as 1,960 words, while the “unique words” section only counts it as one.
“Total words” is more useful for comparing the length of different documents, while “unique words” is more useful for comparing the complexity of different documents.
​
​
​
​
​
​
​
​
​
​
You can use the Library page to directly compare the length and difficulty of different documents, so you can more easily choose what is easiest for your reading level. In this example, the reader already knows all of the words in The Witches. The easiest choice for them to read next is probably going to be Harry Potter, because it has the fewest unknown words.
