NovelOS is a writing studio for serious novelists, made by NovelOS Studio. It keeps the manuscript, characters, timeline, world notes and research in one app instead of spreading them across separate tools. The site describes it as a complete environment for writing a novel, from ideation to revision and export.
The "OS" in the name is shorthand for a single workspace. NovelOS installs on Windows or macOS and runs like any other app, with a phone app for iOS and Android that installs from the browser. It is bought once and stores work locally.
How does NovelOS work?
NovelOS is local-first. Your projects are ordinary files on your own disk, the app runs without an account, and the desktop version works with no internet connection, including narration and export. Nothing is synced unless you export a project archive yourself, and manuscripts are never uploaded for processing.
Optional AI features work differently. You supply a Gemini or OpenAI API key and pay that provider directly. The site says this leaves NovelOS with no margin on your usage and no reason to route your writing through its servers.
Key features of NovelOS
The Manuscript editor handles chapters and sub-chapters with a searchable table of contents. Vanishing Mode hides the line you just typed, Bionic Reading speeds revision passes, and margin notes attach comments to exact words. Snapshots let you compare a chapter with an earlier version, and dictation and read-aloud run on your own computer.
Planning tools include the Blueprint plot canvas with a timeline, character dossiers with family trees, and a world module for places, lore, rules and maps. Smart Import accepts Word, EPUB or PDF drafts, Book Preview shows printed pages, and export covers seven formats plus MP3 or WAV audiobooks.
Key Features
Manuscript editor — Write in chapters and sub-chapters with a searchable table of contents, Bionic Reading for revision passes, and Vanishing Mode, which hides the line you just typed.
Write by voice and read aloud — Dictation runs on your own computer in English projects and adds punctuation. Read aloud narrates a chapter and highlights each word as it is spoken.
Blueprint plot canvas and timeline — Scene cards carry synopsis, cast and setting. A timeline lays scenes out along story days, and moving a scene updates the sequence.
Character profiles and family trees — Each character has a dossier with role, age, era and pronouns, a Soul tab for wants and fears, a Web tab for linked scenes, and a drag-and-drop family tree.
Places, lore and maps — Store places, lore, world rules and dated events as searchable records. Describe a map in words and place names and landmarks on it.
The Oracle, The Architect and The Alchemist — Optional AI drafts three character or place options to choose from, and The Alchemist rewrites only selected words with a reason. It runs on your own Gemini or OpenAI key.
Margin notes and snapshots — Leave comments on exact words, list all notes in reading order, and compare chapter snapshots against the current text.
Smart Import and seven export formats — Import drafts from Word, EPUB or PDF with detected chapters shown first. Export to Word, RTF, plain text, Markdown, EPUB, HTML or PDF.
Book Preview and audiobook export — Preview chapters as facing printed pages with drop capitals and page numbers. Export an audiobook as MP3 or WAV, one track per chapter.
Daily pace and research board — Set a goal and deadline to see words needed per day. Spark Ideas Bank collects notes, images and links.
