Your AI-Powered
Writing Studio.
Brainstorm with it. Draft with it. Edit with it. One rule never changes: nothing is final until you approve it.
Under construction — doors open soon.
Flow one · you write, it edits
She was walking slowly acrosscrossed the very quietsilent room, feeling extremely nervous.rehearsing her lie.
Marcus didn't look up from the ledger. That was the thing about her brother — he could make ignoring you feel like a verdict.
Every cut is a proposal. Accept, reject, or rewrite it — line by line.
An editor that proposes.
An author who disposes.
A full editorial team — one writer in charge. Six ways to put it to work:
Break it down
Split a big project into pieces — chapters, scenes, sections. Each piece gets its own AI conversation that still knows the whole.
The interview
The AI asks the questions; you talk. It keeps digging until the idea is sharp — then your answers become the outline.
It writes the first pass
Hand it the outline and the AI drafts the pages. You leave comments; it redrafts to answer them — as many rounds as it takes.
It marks up your pages
The AI goes through what you wrote like an editor — every suggested change a tracked redline you accept, reject, or rewrite.
Honest notes
A straight read of your pages: what works, what doesn't, and why — feedback only, without changing a single word.
It learns how you sound
Show it pages you've written. From then on, its drafts and edits sound like you on a good day — not like an AI on any day.
Flow two · it drafts, you direct
The house was very old and it had been empty for a long timeDM: too wordy — cut this in half, and Sarah felt afraid as she walked up to the front doorDM: show the fear, don’t name it.
The house had stood empty for thirty years. Sarah’s hand shook on the gate latch.
It drafts. You leave notes. It listens. The same trade, in the other direction.
Editors with training —
not just a model.
Out of the box, AI gives you book-report notes. Every Quillotine editor runs a named, opinionated editorial method — built by a working writer, tuned on real manuscripts. Pick your editor; run the pass.
The Line Surgeon
Hunts limp verbs, filtered action, and dialogue where everyone agrees. Demands tension on every page — and shows the cut that gets it.
The Architect
Maps your chapters against story structure that has held up for a century. Finds the sag in the middle before your readers do.
The First Reader
Reads like your toughest fan: where they lean in, where they skim, where they put the book down. No cheerleading — that's the point.
The Ghost
Learns exactly how you sound, then guards it — flagging every line where the AI, or a tired you, drifted off-voice.
The Proofer
Commas, continuity, timeline slips — and the character whose eyes quietly changed color in chapter nine.
More on the way
New editors join the staff over time — and every one of them works the same way: proposals only. You keep the final say.
Your words are never hostage.
Plain files, forever
Under the hood your book is plain Markdown — no proprietary format, no lock-in, nothing you can't open in any editor on earth.
Export everything, always

A note from Dave
I didn’t build this to sell it.
I’m a writer. Six novels. One work of nonfiction. And as AI got good — really good — my writing flow kept evolving, but my software wasn’t keeping up. I was living in two windows: my manuscript in one, an AI chat in the other, copying and pasting between them like it was 2003.
So I built the tool I wanted. One place where the AI could read my chapters, mark up my pages like an editor, take my notes like an assistant — and never, ever get the last word on my book.
I’ve used it daily since. And at some point I looked at it and thought: wait — can I really hoard this?
Quillotine is me deciding I can’t.
— Dave Mason
