Kolophon

A writing app for novelists

Write your best story.
All the way to the end.

Kolophon is a writing desk built on a craft system. Your plan, your pages, your world and your revision live in one place — and it shows you what every scene is doing, so you always know what to work on next.

For Mac, iPad and iPhone. One email when it’s ready — nothing else.

Kolophon on the Mac: a chapter of The Great Gatsby in the centre, the book's acts and scenes in the sidebar, and the inspector showing the scene's pacing, point of view and threads.

The middle

Novels aren’t abandoned for want of sentences. They’re abandoned in the middle.

Somewhere past the first act the shape slips away. A question you promised the reader goes unanswered. Three scenes in a row move at the same speed. The plot lives in one app, the people in another, the notes in a third. A word processor can’t see any of it. It only knows words.

“I think you are right in feeling a certain slight sagging in chapters six and seven, and I don’t know how to suggest a remedy.”
Maxwell Perkins to F. Scott Fitzgerald, 20 November 1924, on The Great Gatsby

Even Gatsby sagged. Fitzgerald found the cure in the proofs. Kolophon helps you find yours while you’re still writing — and The Great Gatsby is the sample book it opens with.

Only in Kolophon

A writing app that reads your structure, not just your words.

Other writing apps hold your scenes. Kolophon knows what each one is for — and tells you when the page isn’t doing it.

“Your plan has a stake and the page hasn’t.”

Planned, read, and the difference

Say what a scene is for, then write it. Kolophon holds the two side by side at every level, from the story to the beat, and tells you in a sentence where they part.

“Mostly real-time, slow-motion at the couch.”

Dials read off your prose

How much page the time gets, whose eyes we’re behind, what the sentences are made of, how much is shown and how much told — read straight from your paragraphs, by rule, as you type.

“Raised here · what the room holds up.”

The reader’s threads

Every question you plant is a thread the reader carries. Mark where each is raised and answered, and Kolophon weighs them across the book — so the ones left hanging can’t hide.

“Wave 2 · Scene shape.”

Six waves, each asking only what it owes

Plan, zero draft, scene shape, structure, line edit, copyedit. Each pass shows only its own checks, so a first draft is never judged like a final one — and you always know which pass you’re on.

“Who the page names, against who you planned.”

Names on the page

Kolophon reads which characters and places your prose actually names, and shows you where that disagrees with your plan for the scene — the guest who never arrives, the room you forgot you left.

“Was · now.”

Notes that remember

A note keeps what the reader knew at that point in the book when you wrote it. Come back months later and see what has changed since — not just the words, the story around them.

A look around

The desk, as you’ll use it.

See the shape

What you planned, what’s on the page, and the difference.

Every scene has a want, a turn and an outcome. Plan it, write it, and the inspector shows where the two part company: the stake your plan promised that the page never delivers, the question raised and never answered.

  • Pacing, point of view, showing and telling — read straight off your prose, in plain words
  • The reader’s threads: what each scene raises, holds and answers
  • Six waves from first plan to copyedit, so you know which pass you’re on
The inspector beside a Gatsby scene: bands for compression, proximity and medium, and the threads the reader is carrying.

Every level of the book

From the whole story to a single paragraph, one keystroke apart.

Your book is one structure — story, acts, scenes, beats — and you move up and down it with the compass, or across it from the prose to the cards to the plan. Move a scene and the book moves with it.

  • The same book as prose, as cards on a board, and as a plan
  • Scenes you cut are kept off the narrative, never thrown away
  • People, places and events beside the manuscript, each knowing the scenes they’re in
The compass open at the page's corner: story, act, scene, beat and block above it; prose, cards and plan beside it.

Notes where they belong

Select the words. Leave a note. It stays on those words.

Highlight a phrase and say what’s wrong with it. The note sits in the margin beside the line, in a colour that means what you decide, and it finds its words again even after you’ve rewritten around them.

  • Reading mode: the prose alone, for reading back like a reader
  • Your prose width, your note colours, your setup for reading and for writing

Revision you can finish

Every note becomes a task, pinned to its scene.

Notes, findings and loose ideas land in an Inbox. Turn them into tasks, link them to the scene, the character or the thread they’re about, and plan your week with Today and Upcoming — a task manager in the spirit of Things, built for a book.

  • Inbox, Today, Upcoming, Anytime, Someday and a Logbook
  • A writing pace that tells you the words a day your deadline needs
  • Focus sessions and a year of writing days — and no streaks to break

The writers who went before

Every great novel hit the same walls.

Anthony Trollope · the daily draft

He wrote “with my watch before me,” requiring of himself “250 words every quarter of an hour,” three hours each morning before he went to work at the Post Office.

In Kolophon: focus sessions, and a pace set by your deadline.

Charles Dickens · the structure

He planned each monthly part on a folded sheet: questions to himself on the left, what he actually wrote on the right — answered later, often in a different ink.

In Kolophon: what you planned, what’s on the page, and the difference.

Jane Austen · the revision

She finished Persuasion, thought its ending “tame and flat,” and wrote two new chapters. The cancelled draft survives at the British Library.

In Kolophon: every version kept. Nothing is ever deleted.

Your work

Your book stays yours.

On your device

Kolophon’s assistant runs on Apple Intelligence, on your own device. Your manuscript is never uploaded, and never used to train anything.

It reads. You write.

It can read a scene back to you, ask what it’s for, and tidy your punctuation. The sentences are yours — and you can switch it off for a whole book.

Nothing is ever deleted

Every change is a step you can take back. A deleted scene goes to the Trash, not away, and any moment of the last week is one click from being the present again.

Real books out

Your story lives in open files on your own disk, and exports as EPUB, Word, PDF and Markdown, set by templates you can make your own.

One desk

Everything a novel needs, in one place.

Most novels are kept across half a dozen apps that know nothing about each other — about $530 of them in the first year.

Made for the Mac, the iPad and the iPhone

Native, quiet, and fast — with nothing between you and the page.

Kolophon is built with Apple’s own frameworks, so it feels like the rest of your Mac: the keyboard for everything, ⌘K to go anywhere, a reading mode and a writing mode, each with its own setup. Write and plan on the Mac and iPad. Capture ideas and read back on the iPhone.

Questions

Before you ask.

When can I use it?

Kolophon is in development. Leave your email and you’ll get one message, when it’s ready — no newsletter, no drip campaign.

Which devices does it run on?

The Mac and the iPad for writing and planning; the iPhone for capturing ideas, reading back and working through your tasks. One purchase covers all three.

How much will it cost?

One purchase, no subscription. The price will be on this page before launch.

I’m entering a contest that bans AI. Can I use Kolophon?

Kolophon’s assistant doesn’t write your story, and you can switch it off entirely — for a whole project or a single manuscript. Everything else in the app works without it.

Do I need Apple Intelligence?

No. The assistant is the only part that uses it; the writing, the structure, the world, the tasks and the export all work on any supported device.

How do I get help, or tell you something?

Write to us from the support page. A person reads every message.

What happens to my files?

They live on your own disk as open files, not in a database you can’t see into, and they export as EPUB, Word, PDF and Markdown whenever you like.
