Google Docs

Google Docs is a Web-based word processor, spreadsheet, and presentation application. It allows users to create and edit documents online while collaborating in real-time with other users.
Documents, spreadsheets, and presentations can be created within the application itself, imported through the web interface, or sent via email. They can also be saved to the user's computer in a variety of formats. Open documents are automatically saved to prevent data loss, and documents can be tagged and archived for organizational purposes.
