Lucidpress is a wonderful new tool for creating free multimedia collaborative documents. This reminds me of a bit of Google Doc's and Richard Byrne put it best when he said, " look at Lucidpress as being the best of Apple's Pages and the best of Google Documents combined into one slick service."
The way this works is by creating a document and then having a real-time chat going on to collaborate. There are other nice features such as commenting and setting permissions on who can and can't view/edit. Also, this works in a browser so can be used on any device.
I highly recommend checking out Lucidpress by clicking here!!!
