  • PaperlessMe

    PaperlessMe is an HTML5 web app that allows teachers and conference presenters who use PowerPoint presentations to turn their slides into digital “handouts.” Students access the lectures on their laptop computers, iPads and Android tablets, where they can add their own notes and save the files as PDF documents.

    How does paperlessMe work?

    Teachers and conference presenters load their PowerPoint presentations into paperlessMe and enter the day and time of the class or conference session. A unique URL is created for the presentation, which students and conference attendees log onto in class or afterward.
