A writing room for every shape of story.

Maru Writer gives every draft a place to breathe — from short stories to magnum opus novels, and everything in between.

Stay inside the writing

Maru Writer is built around a simple idea: the page should stay central. Not the dashboard. Not the sidebar. Not a maze of panels. The work gets the room, and the tools step forward only when they are useful.

Focus

A quieter writing surface

When you need to disappear into a scene, Maru clears the visual noise and lets the words hold the center of attention.

Range

Small pieces, enormous books

Use it for flash fiction, short stories, novellas, essays, messy drafts, revision passes, and sprawling novels with room to grow.

Keyboard

Fast hands, quiet mind

Maru is keyboard-centered without making you memorize everything on day one. Stay in rhythm, move through the work, and let the mouse become optional.

Trainer

Learn the commands as you write

The built-in command helper keeps shortcuts visible while you learn. When the muscle memory is there, turn it off and take the training wheels with it.

Markdown

Your words stay portable

Maru works with plain Markdown files, so the draft remains readable, movable, and yours outside the app.

PDF Export

Clean pages for the right length

Export clean Short Story or Novella+ PDFs, with manuscript headings stripped when useful, so writing structure does not have to become final-page clutter.

Anywhere

One license, all supported platforms

Continue where you left off* on your laptop, desktop, Linux box, MacBook, or cyberdeck.

*Requires your own file-sync setup, such as Dropbox, Syncthing, iCloud Drive, OneDrive, or similar. Maru Writer does not host your manuscripts.

Themes that feel like home.

A writing theme should do more than change colors. It should create an atmosphere you want to return to: a clean manuscript page, a green-screen terminal, a warm amber desk, or a bright little room with a personality of its own. Click any screenshot to view it fullscreen without leaving the page; click anywhere again to close.

Preview before it leaves the room

When the draft is ready to become pages, Maru gives you a focused PDF preview and export path without turning the writing room into a cluttered production suite. Choose the export path that fits the piece — short story or longer manuscript — and keep writing-only header titles out of the final pages when needed.

Built for every phase of the draft

Begin without ceremony

Open a file, start a scene, test a voice, chase a sentence. Maru keeps the first step light so momentum has somewhere to go.

Return without friction

Markers, headings, counts, and navigation help you find your way back into the work, whether you left yesterday or months ago.

Revise with the whole shape in mind

Move through chapters and passages without breaking the spell of the manuscript. The structure is there, but the page still feels like the page.

Finish cleanly

Preview and export Short Story or Novella+ PDFs when the work is ready to leave the room — without making the app feel like a publishing suite before you need one.

A writing room, not a productivity trap

Maru Writer is for writers who want atmosphere, speed, and restraint — with a keyboard-first workflow that can teach itself as you go. Keep the helper on while you learn the room, then hide it when the commands are in your hands. It helps you stay close to the work across the whole life of a piece: rough notes, first drafts, deep revisions, manuscript passes, and the final export.
