Integrated AI and a shared, versioned project beyond the local file.
Slugline keeps Apple-native writing lean. Choose Inkwell for integrated AI that can analyze or revise the structured screenplay, or for the browser project around it: collaborators, named save points, draft lines, semantic changes, and production handoffs.
Capability spectrum
First-class fills the bar. Partial is half. Empty is a real gap — not a muted icon you have to decode.
Named versions I can return to
Version control
Live Compare places two files side by side and marks what changed. Inkwell does not stop at a one-off comparison: named save points, semantic diffs, and parallel draft lines make version history part of the project.
Live co-writing
Real-time collaboration
Locked production drafts
Production revision colours
Reviewable AI in the draft
AI skill passes
Fountain-native writing

Browser-first for the room
Browser workspace
Slugline is Apple-only; Inkwell's full editor runs in any modern browser.
Not in this matrix: One-time or free start. Those jobs were not scored.
First-hour path
Switching is a file you can name, not a weekend of retyping.
FDX or Fountain from the draft you mean to keep.
Create the shared project before anyone rewrites.
Read the summary. Warnings are decisions, not noise.
A save point is the rollback if the first pass fails.
Export PDF or FDX when production asks — not before.
Stay on Slugline if you want a lean Apple-native Fountain editor, work mostly alone, and Live Compare plus file exports cover your version workflow.
Switch for integrated AI, or when the work needs shared access, named milestones, alternate draft lines, semantic changes, and connected production states.
Yes. A Slugline screenplay is Fountain text, so save or share the .fountain file and import it into Plot. FDX also works when that is the handoff you already created.
Live Compare checks the open Slugline screenplay against another Fountain file. Inkwell save points are immutable moments inside the project, so you can name a table-read draft, compare it later, restore it, or open a draft line without maintaining the second file yourself.
Yes. PDF and Fountain export are available on every Inkwell plan; FDX export is available on Writer and above for desktop and production handoffs.
