Our verdict on Slugline

Slugline is screenwriting software for writers who prefer plain-text drafting with automatic screenplay formatting. It supports Fountain files and converts typed content into industry-standard screenplay structure, while also providing scene synopses, notes, omitted text and screenplay pagination. The product is available on Mac, iPhone and iPad, making it a fit for Apple users who want a focused writing environment across those devices.

Its strongest area is the combination of drafting and story organization. The integrated outline navigator supports drag-and-drop reordering, while the Timeline view helps writers examine story structure and pacing. Live Compare provides revision tracking, and Final Draft FDX import and export supports exchange with Final Draft workflows. PDF and industry-standard print output cover common screenplay delivery needs. iCloud and Dropbox synchronization support file access across supported devices and services.

Pricing is split between the Apple apps. Slugline 2 for Mac is free through page six, then requires a one-time $49.99 USD unlock; the Mac plan includes unlimited writing, Live Compare, Timeline, drag-and-drop outlining and FDX export. The separate iPhone and iPad app provides automatic formatting, integrated outlining, iCloud and Dropbox sync, and print and PDF output. Choose Slugline if you want Fountain support, revision tools and a minimal Apple-based workflow. Writers who need broader platform coverage or a collaboration-centered product should consider alternatives built around those needs.

I've used Slugline myself and this is my honest opinion — nobody paid or asked me to write it.
