What are the software for translation on Mac? I want to translate a long text and I am looking for a software that shows the text and the translation I write at the same time, in two windows and with possibly a synchronization. Does it exist? Otherwise, what are the existing softwares and what do they do ?



PS: I want to translate a 250 page book... I am not looking for a software that does the translation, but for an nice interface where I can do the translation.
If you are asking about professional translation tools (rather than machine transation sites), there is a useful survey that includes some for Mac at

http://en.wikipedia.org/wiki/Computer-assisted_translation

Also can ask on the list devoted to Mac pro translators

(Relying on machine translation inevitably involves substantial risks of potentially embarassing errors, I recommend that the results should always be edited by a pro or native speaker)
