A personal wiki is wiki software that allows individual users to organize information on their desktop or mobile computing devices in a manner similar to community wikis, but without collaborative software or multiple users. Personal wiki software can be broadly divided into two categories: Multi-user applications with personal editions (such as MoinMoin or TWiki), installed for standalone use and inaccessible to outside users, which may require additional software such as a web server, database management system and/or WAMP/LAMP bundle Applications designed for single users, not dependent on a database engine or web server Some personal wikis are public, but password-protected, and run on dedicated web servers or are hosted by third parties. Multi-user wiki software Multi-user wiki applications with personal editions include: MoinMoin desktop edition (written in Python) TWiki for Windows Personal and Certified TWiki (both written in Perl) MediaWiki (powers Wikipedia and many other wikis, written in PHP) DokuWiki on a Stick (written in PHP), which utilizes plain text files (and thus does not need a database like MediaWiki) and a syntax similar to MediaWiki Single-user wiki software There are also wiki applications designed for personal use, apps for mobile use, and apps for use from USB flash drives. They often include more features than traditional wikis, including: Dynamic tree views of the wiki Drag-and-drop support for images, text and video, mathematics Use of OLE or Linkback to allow wikis to act as relational superstructures for multiple desktop-type documents Multimedia embedding, with links to internal aspects of movies, soundtracks, notes and comments Macros and macro scripting Notable examples include: ConnectedText, a commercial Windows-based personal wiki system that includes full-text searches, a visual link tree, a customizable interface, image and file control, CSS-based page display, HTML and HTML Help exporting, and plug-ins Gnote, a port of Tomboy to C++ (although not all plug-ins have been ported) MyInfo, a Windows-based free form personal information manager that includes wiki-style linking between notes, full-text search, different views of the note list, and web-site export Obsidian is a knowledge base and note-taking software application that operates on Markdown files. org-mode, an Emacs mode that can create documents that are interlinked, converted to HTML, and automatically uploaded to a web server TiddlyWiki, a highly customizable personal wiki written in HTML and JavaScript; it is provided as a single HTML file or multiple Node-js files, features many tools and plugins, and has been in active development
