Cloud-native writing, with versions the room can name.
Arc Studio Pro is a cloud editor built around clean outlining and live comments. Choose Inkwell for integrated agentic AI, named save points, alternate draft lines, semantic changes, and production history on the same structured screenplay.
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
Named save points (immutable snapshots)
Arc keeps revision history; Inkwell adds named save points you control.
Live co-writing
Real-time collaboration
Both support live co-writing; Inkwell layers save points and draft lines underneath.
Locked production drafts
Production workflows (locked scripts, revision colors, A-pages)
Inkwell connects locked drafts, WGA revision colors, A-pages, breakdowns, and production exports; Arc focuses on script revision comparison.
Reviewable AI in the draft
Agentic AI skill passes
Arc offers AI assistance; Inkwell runs reviewable skill passes that edit the draft in place.
Fountain-native writing
Fountain native
Inkwell is Fountain-native; Arc focuses on its own structured editor experience.
One-time or free start
Free tier
Inkwell has a permanent Free plan with the full editor. Arc's free tier is a limited script count on a subscription ladder.
Browser-first for the room
Web-based, cross-platform
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 Arc Studio Pro if you want a familiar page-first cloud editor, the outline board is the main job, and you rarely need named restore points or production lock.
Switch when the room is already fighting history — which beat-board version is canonical, which comment landed on which draft — and you want versions, diffs, and AI on structured screenplay data.
Yes. Start in the full Plot editor with a monthly AI allotment. Writer adds complete version control and FDX export; Pro adds production tools; Team adds room-scale collaboration.
Export FDX or Fountain from Arc, then import from Plot's Import / Export menu. Name a save point before you rewrite so the imported pages stay a restore point.
Not yet. Plot's connected Beat Board is planned; today, outline extraction, draft lines, and scene-aware changes keep structural work tied to the screenplay instead of a second board that can drift.
