Web app for taking notes during courses/labs

Goal: To develop a web app that allows students to take notes during courses/labs

Description

The application must allow students to organise their notes by classes they attend and individual study activities. The platform is based on a Single Page Application architecture. It will be accessible on a desktop, mobile or tablet browser (depending on user preferences)(preferably to be responsive). The note editor should be easy to use so that the student can take notes during the class. It will implement a markdown sistem to allow simple text formatting.

Minimal functionalities: As a student I want to be able to login with my institutional account (@stud.ase.ro) to manage my notes.
As a student I want to be able to view, add, edit and delete notes so that I can better organize information (CRUD operations)
As a student I want the option to add attachments (images, documents) to the notes I take so that I can have more details about the subject
As a student I want to be able to organize notes based on classes, date, labels (tags) and keywords so that I can retrieve information easily (see oneNote)
As a student I want to be able to share notes with other colleagues (in-chat feature)
As a student I want to be able to integrate content from other sources and take notes (like for example while I listen to a youtube video, i read a book on kindle, attending an online conference)
As a student I want to be able to organize a study group. I can invite multiple colleagues that will share notes within the group (google docs)
