Mooon one-steps Japanese document processing

Japanese document tooling has been a persistent pain point for learners and researchers, and Mooon's end-to-end automation is a credible stab at making the whole stack disappear.

• –Vertical-to-horizontal layout conversion is genuinely hard — Japanese novels and academic papers use right-to-left, multi-column layouts that break most generic OCR pipelines
• –The self-built million-entry vocabulary database for furigana annotation suggests real domain investment, not just a wrapper around a generic NLP API
• –Bilingual side-by-side view plus TTS audiobook generation means users can read, study, and listen in one tool — strong stickiness for the language-learner segment
• –Manga speech bubble extraction is a nice differentiator that most document tools skip entirely
• –At ¥35/month Pro, it's priced for hobbyists and students — the market it's most likely to convert
