Your outline is the book, not a document about the book

Outlining tends to happen in one app and drafting in another, and the gap between them is where outlines go to die. Writer Studio is free, offline novel outlining software in which the outline is the manuscript: the parts, chapters, and scenes you plan are the same parts, chapters, and scenes you write into, inside one desktop app for macOS, Windows, and Linux. Everything is stored as plain files on your own computer — no subscription, no trial clock, and no account required to write. Plan as loosely or as tightly as you like; nothing you sketch has to be retyped later.

Start from a story structure instead of a blank page

A new book does not have to open on an empty scene. When you create one, Writer Studio offers a start structure: a blank scene, a chapter with a first scene, or a gallery of recognized story-structure frameworks and design methods — 3-Act, Save the Cat, Hero's Journey, the Snowflake Method, 5-Act, Story Circle, and 7-Point — alongside genre starting shapes. Pick one and the app creates ordinary parts, chapters, and scenes with editable titles for each beat or step. Nothing is locked: rename a beat, delete one the book has no use for, or add your own alongside it. A template is a starting shape rather than a contract — which is the point, since an outline that has to stay faithful to its framework stops being useful the moment the book disagrees with it. If you are still choosing, our guide to story structures compares the frameworks, with longer walkthroughs of the three-act structure and the Save the Cat beat sheet.

Outline in the same tree you write in

The Explorer shows your book as a tree — book, optional parts or acts, optional chapters, scenes — and that tree is both the outline and the manuscript. Only the scene is required, so an outline can be a flat list of twenty scene titles today and grow containers next month. Drag a scene into a different chapter and the prose travels with it; there is no second document to keep in step. Click a chapter or a part to read its scenes as one continuous, read-only preview — a fast way to test whether an act actually holds. Every item shows its own word count, so you can see which chapter is quietly running to twice the length of its neighbors. Outlining can also run backward: split a draft you already have into scenes with Extract to Scene, then group them once the shape is clear. The manuscript structure reference covers the tree in full.

Give every scene a job before you write it

An outline of bare titles tells you nothing on the morning you have to write scene 34. Every scene carries a Properties panel beside the text: a synopsis, a status — Outline, Draft, Revision, Final — plus goal, conflict, and outcome, POV type and POV character, location, emotional tone, the cast present, the plotlines the scene carries, tags, and private author notes the AI never sees. Fill in what helps and leave the rest empty; a scene needs none of it to be written. The tree shows each scene's status and can be filtered by it, so "show me everything still at Outline" is a click rather than a reread. Chapters and parts carry their own fields — a part has theme and conflict — and status belongs to scenes alone. The scene properties reference lists every field.

Follow each subplot as its own thread

The part of a novel-length outline most likely to come apart is not the main plot. It is the subplot that goes quiet for a long stretch and then arrives wanting a payoff it never earned. Writer Studio models a plotline as an ordered thread of scenes with its own status: Introduced, Developed, Paused, Resolved. A single scene can belong to several threads at once, so the romance and the investigation advance at their own speeds without either dropping out of view. Membership order follows the manuscript, so moving a scene in the structure moves it in every thread it belongs to — there is no second ordering to maintain. Reading a thread's scene list end to end shows the shape of that subplot alone. What the app will not do is check the story for you: there is no automatic continuity checker. See plotlines for how threads are built.

Outline offline, on your own machine, for free

The core workspace is free: no subscription, no trial clock, no account gate. Your outline, manuscript, and Book Wiki are stored as plain Markdown and JSON files in a folder you choose, readable in any text editor, and the writing experience works fully offline — on a plane, on a train, with the router unplugged. An account is needed only for optional extras such as sharing a draft with a reader. AI is off by default; when you turn it on, the app states plainly where your text would go and lets you switch provider — your own key for a cloud model, a local model through Ollama so nothing leaves the machine, or the managed Authr AI service, which needs no key but does need an Authr Plus subscription. The assistant proposes and you confirm: nothing it drafts reaches the manuscript until you accept it. Research and cut scenes live in Notes, whose words stay out of your counts and your export. Writer Studio is in alpha and under active development.

Novel outlining software that fits how you actually plan

The tree, scene properties, plotlines, and notes are general tools rather than one prescribed method, so the same workspace suits very different planners:

• You plan every beat before you draft — build the beat sheet as real scenes and fill them in order; the Save the Cat beat sheet walks through one such shape.
• You plan by the protagonist's journey — outline the turns first and hang scenes off them; see the hero's journey.
• You outline after the draft — import or write freely, then extract scenes and group them into chapters, the approach in how to organize a novel.

The outline still has to be yours. But it does not have to live in a second file that quietly stops matching the book — download Writer Studio and outline inside the manuscript itself.
