Collaborative real-time editor

A collaborative real-time editor is a type of collaborative software or web application which enables real-time collaborative editing, simultaneous editing, or live editing of the same digital document, computer file or cloud-stored data – such as an online spreadsheet, word processing document, database or presentation – at the same time by different users on different computers or mobile devices, with automatic and nearly instantaneous merging of their edits. Real-time collaborative editing can occur online in web applications such as Microsoft Office on the web (formerly Office Online) – which supports online (web-based) simultaneous editing (which Microsoft refers to as "Co-Authoring") of Word documents, Excel spreadsheets, PowerPoint and other Microsoft Office documents stored on Office.
