Creation of bilingual books
We have developed an original algorithm for aligning literary works and translations at sub-sentence level. Large texts can be aligned and corrected in a relatively short time. To our knowledge, no other technology provides a comparable performance.
In the first step both texts are aligned automatically, ambiguous alignments are marked. The quality is already very good at this stage. After that, we examine the problem areas in the alignment editor, correct them and amend the translations where necessary.
Supported devices and programs
The books are available in multiple formats and can be read on tablets, smartphones, e-readers and PCs.
Interactive ePub files
Browser reading app
Our reading app works on your tablet, PC and smartphone if your device has a fully functional web browser and its screen size allows for comfortable reading of longer texts. Opera Mini is not supported.
An active internet connection is required for logging in and opening the ebook. After the browser has finished downloading the ebook, it can be read offline until the browser window is closed.
Kindle and other e-readers
Download the mobi (Kindle) or ePub (other devices) file to your computer. Connect the e-reader to your computer using a USB cable. Copy the downloaded file to the books folder on your reader. The exact folder name depends on the e-reader model. On the Kindle, the folder is named documents. If you want to read the ebook in the Kindle App on your Android device, the folder name is Kindle. For other devices, please google for sideload your_device_name.
Сlick or tap on the underlined cross-references to toggle between the bilingual version and the original. The ePub files work well on most e-readers.
