Erm I dont know german or anything but..
In english I can express my love for this software quite well.
For those learning the japanese language, sooner or later they'll have to run in to something terrible called kanji, which is basically chinese characters in the japanese language, but with japanese meaning.
It's extremely difficult, and looking up one character can take a mind-numbingly long time if one is trying to simply read and understand a passage of text.
Best used to play visual novels, when combined with AGTH, Atlas v14, and maybe one good solid year of studying japanese, the furigana inserter can basically increase one's capability in understanding what he/she reads to almost fluent. Of course he / she will not read at the speed of a fluent speaker, but he / she will be able to understand at the level of a fluent speaker.
This software is more useful than textbooks or college classes if one holds interest in japanese eroge/visual novels, since you can learn the language while reading an entertaining story.
If you are learning japanese you should download this software right away.
