Your AI-Powered
Writing Studio.
Brainstorm with it. Draft with it. Edit with it. Quillotine puts a frontier AI to work across everything you write — under one house rule: nothing touches your pages until you approve it.
Doors open soon. Founding cohort limited to 100 writers — founder pricing, locked for life.
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.
Other AI tools write over you. Quillotine works the way real editors have worked for a century — in the margins, in red, waiting for your verdict.
Bring the manuscript
Import your draft — or push a project straight in from a Claude or ChatGPT conversation. Chapters, scenes, and notes become a living binder.
Send in the editor
A frontier-class AI reads like a developmental editor, line-edits like a copyeditor, and marks every proposed change as a tracked redline — with its reasoning attached.
You have the final say
Approve, reject, or rewrite each change with one keystroke. Nothing lands on your page without your hand on it. That's the whole point.
A full editorial team,
one writer in charge.
Break it down
Turn a messy project into structured sub-documents — each with its own AI conversation that knows its place in the whole.
Get grilled
The AI interviews you until the idea is sharp. You're the source; it's the extractor. The transcript becomes your brief.
Draft from brief
Generation only from a brief you approved — so the machine writes from your thinking, never its defaults.
The edit pass
The signature move: tracked-change proposals across a chapter or the whole book, each one waiting on your verdict.
Honest notes
A hands-off developmental read that tells you what's broken and why — and never touches the text.
Your voice, kept
Trained on pages you've written, so every proposal sounds like you on a good day — not like an AI on any day.
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
One click downloads your entire project. Cancel any time and walk away with every word. We'd rather earn next month.
