Switch between dark Obsidian Atelier mode and warm Paper reading mode for final proofing, then export Print-Ready PDF (6×9, 5.5×8.5, A5, A4 with margins, running headers, TOC, and bleed), Reflowable EPUB 3.0, Microsoft Word (.docx), and Validated JATS XML—retaining 100% of your royalties ($0 Starter Studio; $14.99/mo Creator with 600 credits).

Every exported file comes with optional 30-day cloud download links emailed automatically to your co-authors, beta readers, corporate stakeholders, or direct buyers—giving solo creators and multi-author publishing teams an end-to-end production pipeline on desktop, tablet, and mobile phone.
