Audience
For readers who use English books as source material for Spanish, French, Japanese, or bilingual family reading.
Many learners already own English EPUBs or use public-domain English literature. BilingualText lets you create a target-language study edition while preserving the English source for comparison.
When English is the original, the translation can become a way to compare phrasing, tone, and sentence structure in Spanish, French, Japanese, or another target language.
English-to-target-language translation can help families, tutors, and independent learners create accessible reading material for private study.
