CtrlMovie Creator is the macOS screenwriting application for interactive films. Write the script as a storyboard of segments that branch where the audience decides — screenplay text, decisions and the logic behind them all live in one document.

Creator brings together what interactive writing usually scatters across a screenwriting program, flowcharts and spreadsheets: the screenplay, the branching structure, the story logic, read-throughs, reader feedback and revisions.
Each episode is a canvas. Segments hold screenplay text in the standard elements — scene heading, action, character, parenthetical, dialogue, transition and shot — and arrows show where the story goes next. Return and Tab move between elements the way screenwriters expect.
Variables record what the audience chose; conditions let the story react to it later. Set a variable when a segment starts, offer a decision only while its condition is true, or let a conditional branch point route the story without asking anyone.
The reader turns the storyboard into one continuous screenplay that stops at every decision. Make a choice, change your mind at an earlier one, and keep each walkthrough as a named path. The reader follows your edits while you write.
Validation lists what would stop a read-through — a decision without an arrow, an episode without a start, a condition that cannot be read — and a double-click takes you to the object. Analyze then plays the script through 100 times with random decisions and reports how long it runs.
Script Share invites readers by email to read a version of the script in their web browser, decision by decision. The script file itself is never handed out. The notes and paths readers choose to share come back into Creator and are marked right on the canvas.
The Sounding Board is an AI assistant in the sidebar. It knows how a CtrlMovie script is built and reads the one you have open. Ask it about the story, have it draft or rework scenes, or let it build structure for you — segments, decisions, branch points and variables.
Creator tracks where the script stands, from the first draft through the coloured production revisions to the continuity script. Lock a version when it goes out, keep scene and segment numbers stable, and pass the script on in the formats a production expects.
Everything it takes to write a branching film happens in one window and one document.
Create a project, add episodes and choose the script layout and language.
Write the screenplay segment by segment, or drag scenes in from a Final Draft file.
Give segments decisions and a default action, and draw arrows to where each one leads.
Use variables, conditions and branch points so that earlier choices have consequences later.
Read the script in the reader, validate it and analyze its running times.
Send a version to readers, work through their notes, then lock, export and print.
Creator is a document-based macOS app. Every save keeps a backup, scripts can be saved with a password, and Quick Look previews a script right in the Finder.
