Use case
A reader who has a TXT, Markdown, or EPUB book with no edition in their language needs the whole book turned into a readable translated file that keeps the original formatting.
Pasting passages into web translators and reassembling by hand, using cloud EPUB translation services that require uploading the whole book, waiting for an official edition, or paying a human translator.
Pasting passages into web translators and reassembling the file by hand is slow and breaks formatting; cloud whole-book translation requires uploading the entire file, raising privacy and copyright concerns; official editions are slow or costly.
xOcto's call
Demand is evidenced
Book translation is shifting from pasted paragraphs to whole-file delivery, with local processing adding a privacy angle; enter through a specific readership — web novels, light novels, paper preprints — and sell finished translations, not another generic tool.
Reason to use it
Why users would choose it
Inferred: it ingests the whole book locally and outputs a translation that keeps the original formatting, removing the multi-step split-translate-reassemble work and the upload step; readers who care about keeping their library private and need a readable translation quickly would choose it when they obtain a book with no existing edition. Fluency still requires the reader's own pass, and no retention or repeat-use evidence exists yet.
Where the easy answer breaks down
The tension worth following
An English validation note will follow from the public evidence.
