- 3
Save what you can’t solve
Snap a photo of any question, crop it, add your answer and a note — it waits in your notebook.

Question Notebook
The question you skipped today is the one on tomorrow’s exam
Every student has those questions: the ones you mean to ask about later and then forget. The Question Notebook keeps them safe until you have really solved them.
- Take a photo, crop it and save it in seconds
- Add the options, your answer, the correct answer and a note
- Filter by subject, grade and source
- Mark each one “Couldn’t solve”, “Will review” or “Solved”
- Scan a book’s barcode to add questions from any book
Friends
Stuck? Ask a friend — right on the question
Find classmates by name or username, send them the exact question you are stuck on and chat about it one-to-one. Share a photo of your solution in the same thread.
For teachers
Homework you can actually follow
Approved teachers open classes, invite students, post announcements and assign homework with a source, page range and due date. Students tap “I did it”; teachers mark it “Complete”, “Incomplete” or “Not done”.
For parents
See your child’s study day — without nagging
Link to your child’s account with a code or a request. See homework, teacher feedback and anything late, day by day, and get a notification when something new arrives.
