01 / WRITE

Keep the words moving.

Screenplay elements and keyboard shortcuts that follow your writing rhythm.

02 / FIND

Know your way around.

Scenes, characters and locations, connected to the page you’re working on.

03 / FORMAT

Industry-standard formatting, automatically.

Move from scene headings to action, character cues, dialogue and transitions without taking your hands off the keyboard. SceneMason applies the screenplay formatting as you write.

04 / KEEP

Your screenplay stays yours.

Write locally, work offline and keep your screenplay off the cloud. Automatic backups and recovery copies quietly protect the draft in the background.

01 / The writing

Stay in
the scene.

Move from a scene heading to action, a character cue, then dialogue. SceneMason handles the element formatting while you work out what happens next.

SceneMason remembers your characters and locations and suggests them as you type. INT./EXT., DAY/NIGHT, transitions and character suffixes are all available directly from the keyboard.

Built-in offline English spellcheck highlights potential mistakes and offers suggestions while you write. Your screenplay stays on your computer.

03 / WORKSPACE

Choose how you write.

F11

Focus Writing

Hide the Navigator and writing bar. Keep editing, with the screenplay in front of you.

Ctrl + Shift + R

Read Mode

Step into fullscreen, read-only mode. Escape returns you to Draft and your previous window.

Light or dark. Optional typewriter scrolling. Your writing environment.

04 / Your work, kept close

Your screenplay belongs
on your computer.

Write offline. Save locally. A cloud writing platform doesn’t have to sit between you and your draft.

A file you can keep.

Choose where your .sm screenplay lives. Open it again from Recent, and keep writing on your computer.

Your work never gets locked away.

If your subscription ends, your existing screenplays remain yours. You can still open them, read them and export them to PDF.

Safety in the background.

Atomic saves, rotating local backups and quiet recovery copies help protect the work between drafts.

A screenplay you can share.

Export a PDF with page numbers and an optional watermark when it’s time for someone else to read.

Your screenplay content stays local. An internet connection is required for initial activation and periodic subscription verification; normal writing works offline between checks.

Frequently asked questions.

Visit support
Does SceneMason work offline?

Yes. SceneMason is offline-first. Initial activation requires an internet connection, and SceneMason periodically verifies your subscription. You can write offline for up to five days after the last successful verification.

Where are my screenplays stored?

SceneMason saves local .sm files in the folder you choose on your computer. Local recovery copies and backups provide additional protection; they don’t replace your manual saves.

Does SceneMason upload my screenplay?

SceneMason’s writing workflow keeps screenplay content on your computer and does not require cloud screenplay storage. License verification communicates with Lemon Squeezy separately and does not send your screenplay content.

What happens if my subscription ends?

On a previously activated installation, you can still open, read and navigate existing screenplays and export them to PDF. Editing and creating screenplays require an active subscription. The same read/export mode applies if online verification is overdue.

How many devices can I use?

The Monthly plan supports 1 device. The Annual plan supports 2 devices. Both include the same screenplay-writing tools.

Can I cancel, and are updates included?

You can cancel your recurring subscription. Both plans include the complete application and all updates. Choose based on billing and device count. Billing details are available at checkout.

SceneMason can check for new versions and securely download updates when you choose to install them. Downloading and installing an update always requires your approval.

Which platforms are supported?

The initial release is a native Windows desktop application. No macOS or mobile version is being offered.
