Obsidian is a notes app. But with the right setup, it becomes a genuine novel writing environment. Manuscript management, world-building, plot boards, character sheets, and if you want it, AI that can actually see your work.
It's free. It works offline. Your files are plain text markdown on your hard drive, not locked in a proprietary format or sitting on someone else's server. If Obsidian disappeared tomorrow, your files would still open in any text editor.
Here's what you need to turn it into a writing app.
The essentials: Longform plugin
The Longform plugin is what makes Obsidian work for novels. Without it, you're just writing notes. With it, you get:
- Manuscript structure. Organise your novel into parts, chapters, and scenes. Each scene is its own file.
- Drag-and-drop ordering. Reorder scenes and chapters by dragging them. Restructure your whole book in seconds.
- Compilation. Combine all your scenes into a single manuscript file. One click and your scattered scene files become a complete document.
It's the closest thing to Scrivener's binder and compiler in Obsidian. Free, community-built, and actively maintained.
Folder structure for a novel
A typical novel vault looks something like this:
One folder per chapter (or part). One file per scene. Longform handles the ordering and compilation. This is where you write.
Character sheets, locations, world-building, lore. Link to them from your manuscript with wiki-style links. Everything stays connected.
Outlines, beat sheets, timelines. Use the Kanban plugin for a visual plot board. Track scene status, subplot arcs, and pacing.
Research, brainstorming, deleted scenes, notes to yourself. The messy thinking that feeds the clean writing.
Useful plugins
All free, all optional. Install what you need:
Out of the box, Obsidian looks like a notes app. With custom CSS, your manuscript pages can look like a clean word processor. Wide margins, readable fonts, no toolbar clutter. The writing experience matters, and you can make it feel like home.
The AI advantage
This is where Obsidian pulls ahead of Scrivener, Word, and most other writing apps.
Your novel is plain text files in folders. Any AI that can read local files can see everything. Your characters, your plot, your manuscript, your world-building. Not pasted snippets. The whole thing.
That means an AI writing partner that actually knows your book. It can workshop your characters, draft scenes in your voice, check continuity across chapters, and stress-test your plot. Every session, without re-explaining anything.
Scrivener uses a proprietary format. Word uses .docx. Neither is easily readable by AI tools. Obsidian's plain text files are readable by all of them.
Obsidian vs Scrivener for novel writing
Binder, corkboard, powerful compiler. A mature, polished experience.
Folder-based scenes, drag-and-drop ordering, single-file compilation. Simpler compiler, but handles most needs.
$49 one-time.
Free.
Proprietary .scrivx format. Your files only open in Scrivener.
Plain text markdown. Opens in any text editor, forever.
None. Copy and paste to external AI tools.
Any AI that reads local files can see your entire vault.
No plugin system. What you see is what you get.
Hundreds of community plugins. Kanban, templates, graph view, custom CSS, and more.
Scrivener is still excellent if you don't need AI and want a polished, purpose-built writing app. Obsidian is the better choice if you want flexibility, plain text files, and AI integration.
The gap: setup
Obsidian is a blank canvas. It doesn't come set up for novel writing. You need to install plugins, build a folder structure, create templates for character sheets and scenes, and figure out how everything connects.
You can do all of this yourself. It's free and the community documentation is good. But it takes time, and if you want AI integration, you also need to configure voice rules, craft skills, and shortcut commands so the AI actually works as a writing partner rather than a generic chatbot.
That's the problem I solved for myself, and then turned into a product.
