The program scans every new
dump for over 30 languages and creates a list of articles with errors.
For a few Wikipedias, the program scans newly revised articles daily, to create a new list for users, omitting already-corrected articles.
A specific interface –
here for the English project – facilitates correcting problems detected by the program in the following three levels of ranking priorities errors. It helps keep the error lists updated in near real time by providing some statistics on corrections made recently.

An
analysis is also performed by
WikiCleanerBot twice a month on the dumps for some of the errors, including some additional errors compared to the
project interface.
