Roadmap

Not a port or an Electron wrapper — a genuine native Windows application built on the same Rust typography engine that powers the Mac version. GPU-accelerated live preview via wgpu, identical PDF and EPUB output, and full feature parity. Your manuscripts and themes work across both platforms without conversion.

Full EPUB 3.3 support with reflowable and fixed-layout options. Embedded fonts preserve your typography, accessibility metadata ensures compliance with distribution requirements, and media overlay support enables read-along audio. Export once and distribute to Apple Books, Kobo, Google Play, and every major ebook retailer.

Footnotes are placed at the bottom of each page with intelligent overflow — if a note is too long, it flows cleanly onto the next page. Endnotes are collected into an auto-generated section at the back of your book. Switch between footnotes and endnotes at any time without reformatting. Numbering updates automatically when you add, remove, or reorder notes.

Bazaar combines the convenience of in-app purchasing with the reliability of local asset ownership. Every bundle is verified, entitlement-protected, and built to work natively with Sappar's rendering pipeline. Launching with a hand-selected catalog of both free and paid ornament bundles managed by Sappar, then expanding into a trusted creator marketplace featuring approved independent designers and studios. A premium destination for the details that elevate a book.

Work on the same manuscript at the same time as your editor, co-author, or designer. See each other's changes in real time with presence indicators. Comment threads on specific paragraphs, tracked changes with accept/reject, and role-based permissions so you control who can edit, suggest, or view. Built for the author-editor workflow.

A visual editor for creating your own book themes from the ground up. Control margins, font pairings, chapter heading styles, ornament selections, spacing, and every typographic detail. Preview changes in real time, save themes to your library, and apply them across multiple projects. For publishers and designers who need a consistent house style.

Expanded hyphenation dictionaries covering 20+ languages for correct word breaks in any manuscript. Each dictionary is tuned for its language's rules — compound words in German, elision in French, syllable patterns in Spanish. Combined with the Knuth-Plass line-breaking algorithm, your paragraphs will be beautifully balanced regardless of language.

Insert images and figures that stay anchored to the right place in your text. Smart positioning avoids awkward page breaks, text wraps cleanly around images, and captions with automatic figure numbering update when you reorder. Supports high-resolution images for print and optimized versions for EPUB.

Every save creates a snapshot you can return to. Compare any two versions side by side to see exactly what changed, restore a previous version with one click, or branch from any point to explore a different direction without losing your current work. Your entire revision history stays with your project.

Pre-configured export profiles for Amazon KDP, IngramSpark, Lulu, and other print-on-demand services. Select your target, and Sappar automatically sets the correct trim size, bleed margins, color profile, and PDF specification. No more guessing at printer requirements — just pick your distributor and export a file that passes preflight on the first try.
