Qipit is a free online tool that allows you to copy documents, whiteboards and handwritten notes with your camera phone or digital camera to store, fax, email or publish. Just take a picture of a document with your camera phone and send the picture from your phone or via email to firstname.lastname@example.org. You’ll receive a link to the online PDF copy of your document, all for free. I have other ways to share my whiteboard slides and notes, but this would be a great tool for students.
