Co-writer

Meet Co-writer.

A collaborator who has read every page. Co-writer knows your characters, places and scenes, talks through what a moment needs, and changes nothing until you say so.

Dalia and the photograph
Marcus is finally bringing back the photograph he hid from Dalia. I want this to hurt, but neither of them should say what they’re feeling. How would you play it?
Read Scene 1, Dalia and Marcus

I’d let Dalia give herself away before Marcus does.

Right now she names the photograph the moment she opens the door. If she starts tidying the counter instead of looking at him, we know she has been waiting for this too. Then she only needs one small line.

Voice

Conversation first.

Co-writer talks like another writer in the room. It asks what you’re going for, offers a way to play it, and explains why before it ever proposes a change.

Approval

You decide what changes.

Every proposal shows exactly what would change on the page. Choose how much Co-writer asks first, and change your mind whenever you like.

Co-writer proposes the new lines for Scene 1 and waits. Nothing on the page changes until you press Accept.

Context

It has read the whole film.

Conversations belong to a project, so Co-writer starts with the context: the prose, the pages, who everyone is, where everything happens and what you plan to shoot.

Full project context is included with Writer and Max.

StoryThe prose, as you write it.
ScriptEvery scene, cue and line.
Characters & PlacesWho people are and where things happen.
WhiteboardThe looks and references you’ve gathered.
ProductionScenes, shots and takes.
ConversationsWhat you’ve already talked through, kept with the project.
Where it lives

Beside the page, or the whole screen.

Keep Co-writer in the sidebar while you write, or give the conversation the whole screen when you’re working something out. Every conversation is kept with its project.
