As a student, one thing that is really hard is when you need direct help for example on homework, classwork, etc. Sometimes a teacher can't always get back to you and help you when you really need help. With a help assistant (the name doesn't have to be flashy. CanvasBot, HelperBot, AssistantBot, those are just suggestions.) it would make it much easier! Honestly i think this idea is brilliant and deserves a chance. Heres two examples one by text and one with a picture of what it should look like.
1) CanvasBot: Hello! I'm CanvasBot! How would you like my assistance?
User: Hi CanvasBot. I need help with homework
CanvasBot: What kind of homework do you need assistance with?
