NOVA Text Aligner is a tool designed to make manual text alignment as easy and simple as possible. It doesn't use any automatic paragraph or sentence alignment algorithms. Why? Because there are things where a human can not be replaced and parallel text editing is such a thing.
There are automated paragraph/sentence alignment tools but there is one thing that they all have in common - they are not 100% accurate (and they can not be due to the nature of the task they are supposed to do). So this means that in the end you'll have to go trough the whole text yourself and check it and correct it. Than why not eliminate the middleman and go manually from the beginning?
NOVA Text Aligner provides you with all editing features that are needed to quickly align texts on paragraph/sentence level. At all times you have full control of the process. Once you have your work done you can export parallel text in a variety of formats including popular Ebook readers formats such as EPUB and MOBI (Kindle). Also professionals will appreciate possibility to read/save TMX (translation memory exchange) files.
It can be used not only to align existing texts but as an editor to do tranlation work from scratch. Just load original language text and you can start translating and have it properly aligned from the begining.
Though designed for professional translators in mind one great way of using it is to create parallel text for your students if you happen to be a language teacher. Or for yourself if you are a foreign language student... With plenty of texts freely available on the Internet it is very easy to create whole parallel books of classics such as Chekhov or Conan Doyle. Or...why not put movie subtitles side by side (original and translation) and have an excellent learning tool!
