GEUL · 글결

Stop transcribing. What Munu says is already in your manuscript.

Geul is a long-form writing studio where the conversation itself becomes 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 ordinary AI tools, the chatbot 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.

Just talk — dump the story in your head…
Braindump — talk once, structure lands everywhere.

Plot board

Chapters

Characters

World wiki

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.

MUNU (文友)

Not a chatbot — a companion inside the manuscript.

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.

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.
