Collaboration
Google Docs
Google Docs is an online environment for editing and sharing documents, spreadsheets, presentations, forms, drawings, and tables. Google Docs documents can be public or private, or shared with anyone with a Google account, e-mailed, or downloaded in various formats, including conversions to PDF and other formats not identical to the original or to the proprietary format used at creation. Designated people with whom items are shared can be given permission to comment or edit the files, thus providing a quick way to collaborate on creating and editing documents and presentations.
Creation
Google Drive
Available as a web-based service and as an app for iOS, Mac, PC, and Android, Google Drive allows users to create, store, edit, and share files across all their devices. Online and offline file access available. Requires a Google account for use, but allows files from Drive to be shared with non-Google users. Drive allows users to upload, store, and share any type of file (e.g., JPEG, MP4, JS, INDD, AI). The majority can be previewed, and many can be edited within Drive. Some files (e.g., DOCX, XLSX, PPTX) can be converted into compatible file types for editing, commenting, and more. Drive is the platform for Google Sheets, Docs, Slides, and many other approved applications. Files saved in Drive sync to all other devices, with an activity monitor that can be useful for version control (see what edits have been made and when, and revert back to previous instances if needed). Offers both free and paid accounts, priced by data capacity: 15 GB (free), 100 GB ($1.99/month), 1 TB ($9.99/month), 10 TB ($99.99/month), 20 TB ($199.99/month), 30 TB ($299.99/month). Teams with more than five people can purchase unlimited storage for $10/user/month.
