The following review written by one of the Software Informer contributors applies to version 0.3
ViiKii Desktop Plug-in is a free plug-in that makes it possible to view YouTube videos with subtitles and captions in your own language. This plug-in is intended for www.viikii.net, a website where we can find many YouTube video with subtitles/captions added by contributors.
These contributors are people around the world who are fluent in two languages (or more): the language of the source video and the language of the subtitles/captions, moreover, they work for no money. It is possible to join this project, and add our subtitles/captions, and/or offer to correct the ones made by other users.
There are many languages available, and we have the possibility to have up to five active languages at a time. Some videos have subtitles in many languages while others have no subtitles at all. After we open a video, we can set to display the subtitles in any language they are available. The videos are classified by categories: countries, music, drama, movies, animations, etc. The highest number of videos are under the drama category, which has more than 850 dramas from all over the world.
This plug-in is delivered free of charge.
