A personal wiki is a wiki maintained primarily for personal use. Personal wikis allow people to organize information on their desktop or mobile computing devices in a manner similar to community wikis.
Single-user application of multi-user wikis
Most community wikis are designed for concurrent use by multiple users. However, most of these are installable for standalone use as well. This may require installing additional software, for example a web server, a database management system, or a WAMP/LAMP software bundle. Nevertheless, this does not mean the wiki must be accessible to outside users.
Some individuals use password protected wikis running either on their own webservers or hosted by third parties. This has the advantage that the personal space can be accessed from any web browser, at home, at work, on a PDA, at an internet cafe etc. Edits made on one machine are immediately accessible on the others.
Multi-user wikis with personal editions
- MoinMoin has MoinMoin Desktop Edition - It is written in Python. It is for Windows, Linux and Mac users.
- TWiki has TWiki for Windows Personal and Certified TWiki - Written in Perl. Both support Windows users.
- DokuWiki works on plain text files and thus needs no database. Its syntax is similar to the one used by MediaWiki and makes sure the data files remain readable outside the wiki. It's written in PHP and is multi-platform.
Wikis designed for personal use
There are also wikis specifically designed for personal use. Their feature set often differs from traditional wikis; examples are:
- Dynamic tree views of the wiki (These are useful because wikis built for personal usage are often small.)
- Drag and drop support for images, text and video, mathematics
- Use of OLE and Linkback to allow wikis to act as relational superstructures for multiple desktop type documents
- Multimedia embedding, in particular wiki can link to internal aspects of movies and sound tracks and stores notes / comments
- Macros and macros constructors. Also often support for alien macros so the wiki can act as a multi scripting macro system
- Built in sharing (a built in lite easy to configure server)
- Much faster handling
