60-second proof tour

Premise to export, with control and cost points visible.

Inspect samples
01

Premise

A concrete seed idea becomes source material, not prompt confetti that vanishes after one chat turn.

Control

Writer supplies, edits, or rejects the premise before machinery starts.

No paid generation is required to read this public demo.

02

Planning board

FictionOS turns the idea into a causal map: architecture, characters, POV, stakes, memory, and chapter plans.

Control

Writer reviews the spine before chapter prose starts.

Planning uses the connected OpenRouter key when run in-app.

03

Voice profile

Voice Studio can compare generic output against profiled author voice so style is not a mood board.

Control

Writer uploads, tests, refines, attaches, pauses, or deletes the profile.

Voice rebuild/test calls use BYOK and are visible before use.

04

Chapter draft

Chapter writing runs through the registry-driven production pipeline, not a blank chat box with amnesia.

Control

Writer chooses tier, mode, chapter count, direction notes, and when to stop.

Chapter cost varies by model, length, retries, cache, and revision work.

05

Quality finding

Programmatic checks look for repetition, explainy prose, cliches, rhythm collapse, and regression drift.

Control

Writer can accept, rewrite, inspect, or export instead of being trapped in auto-polish.

Programmatic enforcers are designed to avoid extra model calls.

06

Revision patch

Review produces auditable targets with approval, rejection, quote, and history rails before finished prose moves.

Control

Writer can run audit-only, guided revision, or controlled automation with a veto.

Revision should quote before mutating finished prose.

07

Export

Work leaves as manuscript, DOCX, TXT, EPUB, analysis, architecture, or JSON backup.

Control

Writer keeps portable copies and can delete projects.

Export is not an LLM spend event.

FictionOS should be judged by artifacts, not slogans: a plan you can inspect, a voice you can test, chapters you can read, revision targets you can approve, and exports you can keep. The author keeps taste, voice, veto power, and final judgment.

She found him in the mirror before she found him in the room, and that was the way it had always been with Cal. He was nursing a whisky he wasn’t drinking. When his eyes lifted to hers in the glass he did not pretend he had not been looking, and that, she thought, was the trouble with him. He never gave her the small mercy of pretending.

Chapter One
The Last Job

Frank had been retired thirty-one years when his daughter knocked on the door. He knew it was her before he opened it—not because he’d been expecting her, but because nobody else came up the back stairs.

She set a manila folder on the kitchen table the way you set down something that might bite. She didn’t sit. He didn’t offer.

She found him in the mirror behind the bar before she found him in the room. He was nursing a whisky he wasn’t drinking, watching the door the way a man watches the weather. When his eyes lifted to hers in the glass, he didn’t pretend he hadn’t been looking. That, she thought, was the trouble with Cal Renwick. He never gave her the small mercy of pretending.

Her heart pounded as their eyes met across the crowded ballroom. She felt a wave of butterflies. He was the most handsome man she had ever seen.

What we protect on every page.

The point isn’t that an AI can write your book. It’s that the system has to keep earning your taste, your voice, and your veto — or you stop it.

01

Voice fidelity

Voice Studio turns representative samples into a reusable profile: rhythm, prohibitions, exemplar passages, and things your prose should avoid. Use Hear It before trusting it on a serious project.

a letter from the founder

The toast was on purpose. The cardigan was the problem.

Christian LeDeBlis
Roubaix, March 2025

The fourth novel I tried to write opens on a Tuesday in November, in a kitchen in Roubaix, with a woman named Édith burning toast on purpose. I have rewritten that scene one hundred and eleven times. I know what she is wearing. I know which of her two husbands is upstairs. I know what the dog is called. I have not been able to make it sound the way it sounds in my head for nine years.

The first three novels are in a banker’s box in my mother’s attic. The third one sold ninety-one copies. I know exactly who bought twelve of them. Two are my aunts.

I built FictionOS because the gap between what a sentence sounds like in your head and what it sounds like on the page is the whole job, and the whole job almost killed the only thing I have ever wanted to do. It is not a chatbot. It is the editor I could not afford, the agent who would not return my emails, and the part of myself that knows what Édith is wearing when my hands are too tired to find the words for the cardigan.

I am still working on the fourth novel. It will be done when it is done. Until then, this is the workshop I wish someone had handed me the night I started — and the burnt toast on the counter when I sat back down.
