Design ships with curated theme presets, trade fiction, literary, romance, commercial, pulp/SFF, memoir, poetry. Each preset bundles a body face, display face, margins, leading, drop-cap style, header/footer treatment, and a scene-break ornament that fits the shelf.

Switch presets in one click; the manuscript reflows live. Tune any of them by opening the panel and changing individual settings, body size, indent depth, justified vs ragged-right, hyphenation, widow/orphan control. Save the result as a custom preset for your next book.

The ornaments library covers scene breaks, chapter-opening flourishes, and decorative dingbats: dingbat dingbats, simple horizontal rules, fleurons, asterisms, and a few illustrated options. You can also upload an SVG of your own, handy for a series mark.

Pick once and the ornament applies across the manuscript in any preset you switch to.

Front matter (title page, copyright, dedication, epigraph, contents) and back matter (acknowledgements, also-by, author bio, request-a-review page) are auto-built from project metadata you've already filled in.

Edit any section by clicking into it. The typography for each section is preset-aware, copyright pages use small caps in the literary preset, mass-market type in the pulp preset, and so on.

Thread ships a basic-quality PDF export, enough to read on paper or send to a beta reader. Spool and up unlock print-ready PDF: trim-size templates (5×8, 5.25×8, 5.5×8.5, 6×9, 7×10, custom), bleed if the cover has any, embedded fonts, and a final pre-flight pass that checks resolution and color space on any inline images.

Files export named cleanly: ProjectName-Interior-trim-date.pdf so a print-on-demand workflow doesn't get confused about which version is current.

Reflowable EPUB 3.2 with semantic markup (chapter, section, footnote roles), an embedded cover, and a generated nav.xhtml. Validated against epubcheck on export, if anything fails you'll see the failing rule with a link to the chapter or section that triggered it.

Available on Spool, Loom, and Tapestry. Inline images are downsampled appropriately for ereaders; full-resolution masters stay in the Media gallery for print.
