NoteGuide is a squared notebook you write in by hand, with a stylus or a finger, and someone who reads back what you wrote. Write as you would on paper: notes or exercises, in any subject. Then you have two buttons. • Check reads the sheet back and marks the mistakes where they are, in red. It works for calculations and for facts too: if you wrote a wrong date in your notes, it tells you. • Hint tells you where to start again when you are stuck, without giving you the solution. You can also import a PDF (handouts, homework, notes taken with another app) and have it checked like any other page. If the exercise is longer than one page, select several sheets and it checks them together. Your notebooks stay on your device. When you ask for a check, the image of the sheet is sent to the model and then deleted: nothing stays on our server. Each check uses a little credit: some may be offered for free, the rest is bought in the app. Writing, drawing, pasting photos and exporting to PDF cost nothing and work offline too. NoteGuide speaks English, Italian, Spanish, Portuguese, French, German, Dutch, Polish, Turkish, Indonesian, Japanese, Korean and Chinese.
