Kiwix

Kiwix is a useful program which allows you to surf the online database for text, while keeping you in an offline environment. You can read content without having an Internet connection, for instance.

The interface of the application is clean and intuitive, so navigating through its features shouldn't be too much of a hassle. You can download a wide range of databases provided by Kiwix, which contain dictionaries, encyclopedias, books and other readable text; they are available in multiple languages.

Downloading an item can take a while, since its size can be pretty consistent. Afterward, the database is stored to a library from where you can easily access its contents. Kiwix's features allow you to use a search function, sort items (by size, date, author or publisher), zoom in and out of a document, switch to full screen mode, and invert the colors.

From the 'Tools' menu, you can select an IP port to listen to, pick a random article, check an article's integrity, as well as purge history. Kiwix may also be set to remember tabs and to stop downloading remote catalogs. It is possible to save pages to the HTM, HTML, TXT, TEXT or PDF format.

The program supports multiple languages and skins for the UI (along with keyboard shortcuts), includes user documentation, and needs a low amount of system resources to work properly. No error dialogs have popped up during our testing. Less experienced users may quickly discover how to work with this app, thanks to its overall simplicity.
