Stop transcribing. What Munu says is already in your manuscript.
A long-form writing studio, geul turns the conversation itself into structure — plus a deep-focus editor, a nine-tool bubble menu, and one-click publishing. Local-first: your words live on your device before anywhere else.
BRAINDUMP
The conversation becomes the manuscript's structure.
With most chat tools, the assistant talks and you do the labor — copying its plot into one app, pasting characters into another. In geul you brainstorm with Munu once, and the plan lands in the plot board, chapters, characters, and world wiki by itself — you just review each card and check it off.
Plot board
Chapters
Characters
World wiki
Pour it out
Tell Munu the story living in your head — messy is fine. "A failed swordsman meets a talking tiger, and I want a betrayal in the middle…" No order, no format.
Munu sorts it into five drafts
One pass becomes five drafts in their right places: synopsis, characters, world wiki, plot board, and a chapter list — each as cards you can read at a glance.
You check only what you like
Nothing lands without your check. Keep the tiger, cross out the betrayal — only approved cards enter the manuscript, and everything stays editable afterwards.
Why it matters: the hardest page of a novel is the empty first one. A braindump means you never face it — you start from a filled room, not a blank screen. And because the plan lives in the plot board and chapters (not in a chat log that scrolls away), the structure remembers your plan while you write against it.
BUBBLE MENU
Nine revision tools, floating on the sentence.
Select once — swap a word, shift the tone, rewrite, expand, condense, deepen description, show don't tell, continue the scene, or just ask. Every result lands back exactly where you selected.
The sea swallowed the last light, and the boy said nothing.
One word not landing? Get a handful of sharper alternatives.
EDITOR
An editor built for the long haul.
Typewriter scroll
The line you're writing stays anchored mid-screen, like paper rolling under a typewriter.
Focus mode
Everything but the manuscript fades out. Just you, the rice paper, and the sentence.
Adjustable page width
Narrow column for prose rhythm, wide for revision passes — set the measure you think in.
Find & replace (⌘F)
Full-manuscript search with replace — rename a character across forty chapters in one pass.
Auto-correction (IME-safe)
Smart quotes, dashes, and your own substitution rules — built to never fight CJK input methods.
Repetition map
See the words and phrases you lean on too often, mapped across the whole manuscript.
Writing timer
A draggable session timer that tracks minutes and characters — small rituals keep long books moving.
Bring an old draft in
Import a TXT, Markdown, or DOCX file — geul guesses the genre and proposes a chapter split, and you confirm before anything is written.
The writing calendar
A quiet grid of grass, one square per day you wrote — no streak alarms, just a season taking shape behind you.
A bookshelf on your home screen
Your manuscripts, spines out, sitting on your home screen — a glance at the shelf you're building.
MUNU (文友)
Not a chatbot — a companion inside the manuscript.
Why it matters: a chat tool forgets your chapter 3 by chapter 12 — so you re-explain, paste context, and still get a hero acting out of character. Munu lives inside the manuscript: it keeps a rolling recap of where the story stands, searches your own chapters before answering, and shows which chapter each answer leans on. "Continue writing" starts from where you actually stopped — not from amnesia.
Four modes
Chat, write, plan, revise — Munu shifts stance with your work, from brainstorming to line edits.
Knows your manuscript
Munu answers with your chapters, characters, and world wiki in mind — not as a blank chatbot.
Three thinking depths
Fast, Balanced, Deep — pick how hard Munu thinks, not which model runs. Switch mid-sentence.
Per-manuscript style
Each manuscript keeps its own voice settings — everything Munu writes follows that grain, without exception.
Plan, then act
When a task spans many steps, Munu drafts a plan first. You approve it, then it runs — and if anything feels wrong, one card undoes the whole thing at once.
The polish pass
A separate touch that only tunes the rhythm of what you just wrote — no new events, no new characters, and the length stays exactly where it was.
Knows when a scene is done
If the last beat already tied things off, Munu won't pad the same scene — Munu skips ahead in time and steps into the next phase instead.
A library of voices
Feed Munu a writing sample and Munu extracts the voice behind it — down to the habits in how your sentences end — then saves it to reuse on any manuscript.
Two or three ways to say it
Pro plan · Balanced+For a pivotal line, Munu can lay out two or three prose candidates side by side — pick the one that sounds most like you.
The Changsin-dong Story
Novella / mid-length
1. A Familiar Crack
I looked out the window one last time before drawing the curtains. At the end of the alley, the empty houses awaiting demolition hung open like a black gaping mouth.
And in that darkness, something seemed to be looking back at me.

Annotations & chapter locks

Sweep the manuscript for cast and world
