Many teachers and students are using Google docs collaboratively. They allow us to highlight passages of writing and leave text comments in the margins which can be responded to and eventually, marked as resolved.

These text-based conversations are great, but students and teachers may prefer to leave audio comments. Audio commenting was possible before but only on a whole document basis. This has all changed now with a new Google Docs “Add On” called Kaizena.

Kaizena is a service that, once you allow access to your Drive, gives you the ability to:

• highlight a passage in a Google Doc
• leave a text comment, an audio comment, or attach a resource to the highlighted passage
