Frame Bench is a nice service for sharing PDFs, images, videos, and other files with colleagues and students. Within Frame Bench you can create multiple workspaces to share files with different contact groups. When you upload a file to a workspace everyone who has access to that workspace can see it. In the workspace you can mark-up the file with drawing tools and text comments. If you’re working at the same time you can use the chat features to host live discussions about the files you have shared in your workspace.

Applications for Education
Frame Bench could be a great tool for teachers of graphic design to use to give feedback to their students. Students could use Frame Bench to give each other feedback and collaborate on the creation of a visual project.

Frame Bench offers a variety of plans. The free plan allows you to share up to 30 files at a time.
