WriterDuet alternative
Real-time collab plus history that names moments.
WriterDuet is built around live co-writing and offers AI-assisted proofreading through ScreenplayProof. Inkwell supports the same room workflow while adding agentic AI that analyzes or revises the structured draft in place, named save points, draft lines, and semantic changes to the shared project.
What WriterDuet does well
- • Established real-time collaboration for writers' rooms.
- • A browser editor; the desktop app is on its paid plans.
- • Fountain and FDX import/export workflows.
Why writers switch to Inkwell
- • Draft lines for parallel alternate versions — not just live editing.
- • Named save points you control — not only automatic history.
- • Connected production workflow with revision colors, locked pagination, A-pages, and delivery exports.
- • Integrated agentic AI — skills and Agent Mode work on the structured draft, with reviewable outputs kept in the project.
Capability spectrum
First-class fills the bar. Partial is half. Empty is a real gap — not a muted icon you have to decode.

Export PDF or FDX when production asks — not before.
Who should stay on WriterDuet?
Stay on WriterDuet if live co-writing, conventional revision history, and AI-assisted proofreading cover the room, and you do not need in-project agentic AI, named milestones, alternate draft lines, or connected production work.
Who should choose Inkwell instead?
Switch when the room needs in-project agentic AI, named table-read versions, alternate draft lines, reviewable changes, and production continuity alongside live collaboration.
Does Inkwell support real-time co-writing?
Yes — presence, comments, and shared projects. The collaboration guide covers invites and reads.
Can I import WriterDuet exports?
Use Fountain or FDX exports from WriterDuet and import via Plot's Import / Export menu.
Is WriterDuet free?
Within limits. WriterDuet's free plan holds three projects, collaborators can only read, and writing together and the desktop app are on its paid plans. Plot's free plan gives you the full editor and a monthly AI allotment.
Can I download WriterDuet?
WriterDuet's desktop app comes with its paid plans; the free plan writes in the browser. Plot runs in any browser with nothing to install, and imports the Final Draft or Fountain files WriterDuet exports.
