Spark holds the raw material of a novel inside the same project that will eventually contain its manuscript.
Spark holds notes, images, audio, video, links, and drawings on a free-form board before the material is ready for an outline. The Oracle, an optional AI tool that runs on the writer’s own key, drafts three character concepts to choose from and edit, without turning that exploratory material into the manuscript’s authority.
Cast records preserve identity, biography, appearance, psychology, motives, fears, moral alignment, voice, habits, strengths, weaknesses, images, and associated scenes. Relationship and genealogy views make personal ties visible, which helps a novelist trace how a secret, inheritance, rivalry, or family obligation changes the plot.
Worldbuilding records places, cultures, objects, history, rules, imagery, and scene associations. The Architect, an optional AI tool, drafts places and items for the writer to edit, while Cartography generates a map the writer reshapes and labels. Setting facts stay close to the scenes that depend on them instead of becoming a detached reference wiki.
Blueprint supports multiple boards with scene, entity, and plot-point cards. A scene carries the chapter it is written in, a status, a viewpoint character, a synopsis, cast, location, and objects. The timeline then lays every scene out chapter by chapter, and dragging a scene to another chapter moves it, so a structural change is checked before it creates a continuity problem.
Manuscript keeps chapters and sub-chapters beside search, statistics, typography controls, and drafting modes such as Zen, Typewriter, Vanishing, and Bionic Reading. Dictate writes the chapter by voice on the device itself, in English projects. Margin notes attach a comment to the exact words selected, and snapshots keep old copies of every chapter to compare and restore.
Goals and progress tracking connect the word target and deadline to completion, required daily pace, days remaining, current streak, today’s output, active days, averages, annual activity, and project statistics. The Alchemist, optional and on the writer’s own AI key, suggests a rewrite of the words selected and shows it beside the original, so every change stays the writer’s decision.
The publication workflow exports DOCX, RTF, TXT, Markdown, EPUB, standalone HTML, and PDF from the same manuscript. Book Preview shows the pages at the chosen trim size first, and the PDF follows that trim size, its margins, and its font. A separate .novelos archive preserves the editable database, prose, media, boards, timeline, cast, worlds, lore, genealogy, comments, manifest, and checksums for transfer to another computer or to the phone app.

|---|---|---|
| Planning the novel | Multiple Blueprint boards, plot points, connected entities, scene order, and Timeline | Organizes front matter, chapters, back matter, and book elements for production rather than visual plot architecture or story chronology |
| Drafting and revision | Smart Import reads Word, EPUB, Markdown, plain text and PDF with a text layer, and shows the detected chapters for you to check | Imports DOCX and detects chapters, text features, images, and character formatting |
| Finishing and delivery | EPUB plus standalone HTML for digital reading, alongside portable text and editorial files | Validated EPUB 3 or optional EPUB 2, optional MOBI for Kindle, store-specific files, image optimization, box sets, and accessibility features assessed with Ace by DAISY |
Each scene is linked to the chapter it is written in and the timeline is arranged by chapter, so a structural change stays visible when you revise the prose.
Relationships, genealogy, maps, lore, objects, locations, and scene associations give recurring facts a defined place.
Track completion, required pace, days remaining, streaks, today’s output, active days, averages, and yearly activity beside the draft.
Core work is local-first, the lifetime personal license costs $45 once, and one key activates the desktop apps and the installable Android and iOS app.
Publication files serve editors and readers, while a separate .novelos archive preserves the source for another computer or the phone app.
Vellum deserves an honest place in this comparison. The capabilities beside this are its documented strengths, taken from the official sources at the foot of this page.

Keep the original project intact until the new project has been checked. Export or back up the manuscript through the documented Vellum workflow. Smart Import brings the prose in with its chapters. Characters, world notes, and plot boards are rebuilt by hand, because there is no importer for another application’s project file.
Keep the original project and a backup. Export the manuscript as Word, EPUB, Markdown, plain text, or PDF, and open it with Smart Import, which finds the chapters and shows them for you to check.
Recreate the characters, relationships, locations, rules, objects, and lore that still influence the manuscript.
Link each scene to its chapter, then add viewpoint, status, synopsis, cast, locations, and plot points.
Read the story chapter by chapter on the timeline, set the manuscript target and deadline, and confirm that the active draft is authoritative.
Look at the pages in Book Preview and open sample DOCX, EPUB, and PDF files. Create a .novelos archive and test its import before relying on the new project alone.
Windows and macOS applications, an installable Android and iOS app on the same key, portable .novelos archives, and one $45 lifetime personal license support long-term ownership.For a novelist who needs story coherence from first premise through publication, NovelOS Studio is our recommendation.
Own the complete novel-writing studio.
One $45 payment for the owner’s supported Windows and macOS computers, plus Android and iOS. No recurring subscription.
Windows novelists who need planning, characters, relationships, genealogy, worldbuilding, maps, plotting, timelines, drafting, goals, revision, ebook output, and a PDF at the book's trim size in one local-first project. It costs $45 once and also runs on macOS. Vellum remains a strong specialist formatter, but its official requirements say it is available only for Mac. Windows and macOS computers and includes planning, drafting, goals, revision, EPUB, PDF, and five other delivery formats. macOS 13 or newer. NovelOS Studio has native Windows and macOS applications. A Windows author can complete the book in NovelOS without maintaining access to a separate Mac solely for book production. These comparisons address nearby workflow decisions without replacing the focused Vellum analysis above.
Vellum facts were checked on August 2, 2026 against the first-party sources linked here. NovelOS claims were checked against the current application source and product documentation.
The recommendation separates documented capability from workflow judgment. It preserves the competitor’s documented strengths while answering a narrower buying question: which application gives an individual novelist the more complete path from discovery and story architecture to drafting, progress, publication, and long-term project ownership?
The table also keeps unlike capabilities separate. Manuscript exports are delivery files, while a restorable project archive preserves editable application data. Desktop availability is separate from mobile access. Local offline work is separate from cloud synchronization and live collaboration. A specialist can lead one stage of the process without replacing the complete production environment. Those distinctions are used consistently when NovelOS receives the overall recommendation.
