SubEthaEdit is a tool that allows several people to take notes simultaneously in the same document. While it doesn’t work in every situation, it can be a surprisingly good way to capture everyone’s point of view quickly and without interrupting the flow of the meeting.
The example above shows SubEthaEdit being used to write a program with multiple people contributing at the same time. Each person’s changes show up in their color and you can see the changes they are making in real time.
SubEthaEdit is designed to create plain text files, so you can’t do any fancy formatting, but for large groups of people, this helps keep the documents consistent. The newest version allows you to save out a file as HTML with tooltips that tell you who wrote each part of the document.
SubEthaEdit is free for non-commercial use, so you can try it out for free. It only runs on OS X. You can find more information on the product website.
