Consider an online collaboration tool that lets employees work together in real-time, creating and editing documents regardless of their location. Users can easily create teams who work together in one single workspace by inviting colleagues via e-mail. Once the invitation is accepted, all of those in the team can begin uploading and editing documents and also assigning each other tasks. It allows co-workers to see each other's changes to documents in real-time, as they are being typed. The tool keeps track of all the changes made and keeps the original documents available, which is one of its most useful features. There are also a smart phone application for both Android and iOS phones. It has a highly intuitive easy-to-use interface, so those who have never used an online collaboration tool before will be able to quickly figure out how to make the best of all the features provided within 1 hour of using the application. Its free account lets users store up to 100 MB in files, so it is plenty for those who work mainly with word processor documents.
