Lucidpress is a slick new service from the same team that developed Lucidchart. Lucidpress is a slick tool for collaboratively creating multimedia documents.
If you watch the video below you'll notice that Lucidpress has some similarities to Google Documents. In fact, you can use your Google Account to sign into Lucidpress and you can use items stored in your Google Drive account in your Lucidpress documents. Lucidpress has commenting and sharing features that are similar to Google Drive too. What makes Lucidpress different from Google Documents is the selection of layouts and the layout customizations available to you. I look at Lucidpress as being the best of Apple's Pages and the best of Google Documents combined into one slick service.
