Kami is a neat service that makes it easy to annotate and comment on PDFs. The folks at Kami describe their service as a digital pen and paper. That is an accurate description of what the core of the service provides. The core function of Kami provides you with a place to draw, highlight, and type on a PDF. You can share your PDFs in Kami and write notes in the margins for others to see and they can do the same.
Create a free account to start using Kami. Once you have created your account you can import PDFs into Kami from your Google Drive or you can import them from your desktop. Kami can be integrated with Google Classroom to make it easy to share annotated PDFs with your students and for them to share with you.
Kami’s core service for drawing, commenting, and annotating PDFs is free for all users. Kami does offer the option to upgrade to a premium account. The premium version includes options for adding voice comments and video comments to your PDFs. The premium version also supports conversion and use of Word documents.
Applications for Education
Kami could be used by students to annotate historical documents that have been scanned and saved as PDFs. For example, many of the featured daily documents from the U.S. National Archives are PDFs.
