What is PaperShala?

PaperShala is a free web-based application for reading, annotating, and collaborating on documents. It allows users to upload their own PDFs, Microsoft Office documents, and images, or search PaperShala's content library to find publicly available documents to annotate.

Once documents are uploaded or selected in PaperShala, users can highlight passages of text, add text boxes with comments or notes, draw shapes and diagrams, insert images, and more.
