Step 1
Build your story foundation
Start with the premise, project type, tone, voice, world rules and story bible. Add only the structure your project actually needs.
The Writing Operating System For Serious Authors
The world's most advanced writing OS for authors building complex stories or detailed non-fiction
Folian is a private desktop writing workspace for novelists, screenplay writers and long-form non-fiction authors who need more than a blank document.
It gives serious writing projects a place to hold the manuscript, story bible, canon, research, decisions, structure and optional AI support together, so the work can grow in complexity without losing its shape.
Use Folian to draft your manuscript, organise the world around it, protect the truth of the project and move from idea to revision with more control.
Built for novels, series, fantasy worlds, screenplays, long-form non-fiction, memoirs and complex story projects.
The problem
Most writing apps were not built for projects that become this complicated
A serious writing project is never just a document.
A novel, screenplay or detailed non-fiction book gathers weight as it develops. Chapters move. Scenes change. Characters deepen. Research expands. World rules become more precise. Earlier decisions start to matter in ways the writer may not have expected at the beginning.
The problem is that most writing workflows are not built to hold that complexity. The manuscript sits in one place, notes in another, research across tabs and documents, character details in scattered files and AI suggestions buried in old chat threads. Over time, the project becomes harder to trust because the truth of the work is no longer held in one coherent system.
That is when canon drifts, revision choices get forgotten, character details change and research becomes difficult to find at the moment it is needed.
Folian is built for this part of the writing process. It gives authors a private writing OS where the manuscript, story bible, canon, decisions, research and optional AI support each have a clear place to live.
Writing OS
A book needs more than a place to type
A blank page is useful, but it is only one part of the work. A notes app can collect fragments, a folder can hold files and a chatbot can generate text, but serious long-form writing needs something more connected. It needs a system that can hold the manuscript alongside the research, story bible, canon, characters, structure, style rules, revision thinking and decisions that shaped the project.
Folian is built for the layer underneath the manuscript, the part of the process that keeps the work coherent while it grows.
For a short piece, loose notes and a prompt may be enough. For a novel, screenplay, memoir or detailed non-fiction project, the system around the manuscript becomes part of the craft. It helps the writer remember what has already been decided, what is still open, what belongs to the story and what should be left behind.
Folian connects the manuscript to the wider project, so authors can plan, draft, revise, research and use optional AI support with more context and more control.
AI is optional
A writing OS first. AI when you want it.
Folian is not built on the assumption that AI should replace the author. It is a private desktop writing OS for planning, drafting, story bible, canon, research, decisions, revision and manuscript control. You can use Folian without AI at all, as a serious writing system for structuring a novel, managing a screenplay, organising long-form non-fiction, building a story bible, tracking canon, saving research and keeping a complex project together.
If you choose to use AI, Folian is designed to make it more useful by giving it better project context. Instead of asking a model to work from a blank prompt or a disconnected chat thread, you can bring your own preferred AI provider, connect your own API key and decide where AI belongs in your workflow.
The author remains in control of the work. Folian gives the project structure. AI is optional support.
The promise
Write with more structure without handing over control
Folian helps authors move from idea to draft to revision without losing the choices that shaped the work.
It is not a one-click novel generator, and it is not a machine that takes the book away from the writer. Folian is a writing OS for authors who want stronger project memory, clearer structure and better control over the full manuscript.
Use Folian to draft scenes, organise chapters, build a story bible, manage research, protect canon, save decisions, revise with more confidence and export clean project materials when the work is ready.
If you choose to use AI, it works inside the structure of the project. It can support drafting, critique, research, continuity checks, chapter planning and revision, but the writer decides what becomes manuscript, what becomes canon, what becomes a saved decision and what gets discarded.
- Draft scenes with project context close at hand.
- Organise characters, locations, lore, research and world rules in one structured workspace.
- Keep canon stable across long manuscripts, screenplays, non-fiction projects and series.
- Save options, questions, editorial concerns and chosen directions in Decisions.
- Use optional AI support without silent rewrites or hidden retcons.
- Export clean manuscript, canon, research and handoff files when the work is ready.
How it works
From story idea to final manuscript, keep the project coherent.
Step 2
Draft with your canon nearby
Write chapters and scenes while keeping characters, locations, worldbuilding and story rules visible and consistent.
Step 3
Use AI with context and boundaries
Ask for drafting help, revision support, story options, continuity checks or editorial critique. Folian uses the project context you choose.
Step 4
Save what matters
Turn useful AI output into manuscript text, Decisions, chapter memory, canon entries or revision notes. Nothing important has to vanish into chat history.
Step 5
Revise and export
Use editing workflows, snapshots and export tools to move from rough draft to polished manuscript or handoff file.
Features
Built for the realities of serious creative work.
Folian is designed for the full shape of a long-form writing project: manuscript, story bible, canon, planning, revision, research, decisions and optional AI support.
Story bible and canon management
Keep characters, locations, world rules, history, lore, timelines and reveal-sensitive truth in one structured workspace, so the book has a memory before, during and after the draft.
Novel writing software for complex manuscripts
Organise chapters, scenes, revision notes and manuscript structure without turning the work into a mess of files, folders, chat threads and forgotten notes.
AI writing support for authors
Draft, revise, analyse and critique with AI that can work from your project context instead of a blank prompt, while the writer stays in control of what belongs on the page.
Chapter and scene planning
Create chapter briefs, scene goals, reveal boundaries, pacing notes and revision targets before drafting, so every part of the manuscript has a clear job.
Continuity-aware workflows
Give AI access to relevant canon, chapter memory, character notes, style guidance and open decisions when the task needs it, so support is grounded in the actual book.
Research conducted with the help of AI
Use AI to streamline research, summarise useful findings and save relevant notes directly into Folian, so research becomes part of the project memory instead of disappearing into scattered tabs and documents.
Decisions workspace
Save options, questions, editorial concerns, rejected paths and chosen directions, so your reasoning stays visible and the book does not lose the thinking behind the draft.
Editing and revision support
Use critique, rewrite suggestions, tracked editorial thinking and safer revision workflows before applying changes to the manuscript.
Bring your own AI API keys
AI in Folian is completely optional. Use Folian as a powerful writing OS on its own, or connect your preferred AI provider with your own API key to enhance research, planning, drafting and revision workflows.
Private desktop writing app
The first tester build stores projects locally on your computer and works without cloud sign-in, so your manuscript and project files stay on your machine.
Export tools
Take your work out of Folian as manuscript bundles, document-shaped outputs, canon files, project backups and handoff materials.
Style profiles and voice guidance
Capture the tone, rhythm, point of view, sentence movement and writing preferences that define the book, so AI support has clearer guidance and does not flatten the author's voice.
AI control
AI writing help without losing authorship.
Many AI writing tools treat the chat as the workspace.
Folian treats AI as one part of the writing system.
AI output appears for review before it touches the manuscript. You can apply it, refine it, save it as a decision, turn it into canon or reject it. The assistant should support the book, not quietly rewrite the truth behind it.
- Choose the source scope for AI tasks
- Use AI for drafting, revision, analysis and critique
- Review AI proposals before applying them
- Keep canon changes visible and intentional
- Save useful ideas into Decisions
- Preserve style with project prose rules and style guidance
- Use AI only when it helps
The goal is not to generate more text.
The goal is to help writers make better decisions and protect the story as it grows.
Story bible software
Keep your story bible connected to the manuscript.
A story bible is only useful if it stays close to the writing.
Folian keeps canon, characters, locations, worldbuilding, lore, timelines, relationships and reveal rules connected to the manuscript and chapter structure.
If a scene creates durable truth, you can promote it into Canon. If an idea is still uncertain, save it into Decisions. If a chapter needs to remember a chosen direction, keep it in chapter memory.
Your story bible becomes a working part of the writing process, not a separate document you forget to update.
Private desktop writing app
Built for private, local writing.
The first Folian tester build is a local desktop writing app for a single writer using one Windows computer.
Your projects are stored locally on your machine. You can create, edit, save, reopen, back up and export projects without cloud infrastructure.
AI is optional. If you use it, you add your own API key. If you do not, Folian still works as a structured writing workspace.
- Local desktop app for Windows testing
- Projects stored locally on your computer
- No cloud sign-in required for the tester build
- Backup and export tools included
- AI works only after you add your own API key
- Writing workspace works without AI
