Slugline

What Slugline is

Slugline is screenplay-writing software for iOS and macOS that formats a screenplay as you type. It uses Fountain, a free, open text-based format, and Slugline 2 can produce paper and PDF screenplays with industry-standard formatting and pagination. The Mac version includes Dark Mode, a drag-and-drop Outline Navigator, and a Timeline for viewing structure and pacing. Live Compare checks the current screenplay against another document and marks changed text with asterisks. Slugline can open and export Final Draft files, including dual dialogue and notes, and supports Fountain, Final Draft FDX, and PDF exports. On iPhone and iPad, users can write and edit screenplays and create print and PDF output without the Mac app. Mac and mobile editions can share files through iCloud or Dropbox. Slugline deliberately does not offer controls for screenplay margins or most formatting settings. A Mac plan is listed at $49.99, paid once, with writing through page six before the unlock; another Mac plan is listed at $49.99 a month.

Slugline suits screenwriters who want automatic formatting and outlining across Mac, iPhone, or iPad. Its limited layout controls may suit writers who prefer not to manage margins and most formatting settings.

Limits

The Mac edition is free through page six; $49.99, paid once unlocks Unlimited Writing and FDX export. The listed Mac Unlimited Writing plan is $49.99 a month.
