Audience
For language learners who want translation nearby without giving up the experience of reading a complete book.
Parallel text reading is useful because it keeps meaning close to the source text. BilingualText applies that idea to full EPUBs so learners can compare grammar and sentence flow inside chapters, not only in short examples.
Dictionary lookup is useful, but it can fragment the reading experience. A parallel text EPUB gives you enough context to keep moving and revisit difficult passages later.
The format is especially useful for Spanish, French, Japanese, or English because those language pairs have plenty of EPUB reading material.
