WikiTaxi enables you to read, search, and browse Wikipedia offline. No Internet connection is needed, all pages are stored in a WikiTaxi database. Because Wikipedia is constantly growing, WikiTaxi uses compression to make sure that the database stays reasonably small. The huge English Wikipedia easily fits on a 8 GB memory stick.
WikiTaxi is multilingual, which means that you can use it for Wikipedias from different languages (see screenshots). It also works well with the dictionary and quotation Wikis, if you like. You can also save multiple Wikis to disk and use all of them with WikiTaxi.
WikiTaxi is up to date. It works with the original Wikipedia database dumps, which are updated regularly every few weeks or so. If you feel that your offline Wikipedia is getting too old, you can go online to download a more recent version or just copy it from a friend.
