Planned for the cut
Scene time estimates and authored board durations help you judge rhythm before you shoot or generate a frame.
NATIVE FILMMAKING WORKSPACE FOR MAC · EARLY ACCESS BETA
ScreenplayOS™
From first beat
to first cut.
ScreenplayOS keeps the edit in mind from the very first beat. Outline, write, break down shots, board, and play a timed animatic in one connected project, then export timing guides for the tools your team already uses.
Free to write. Works offline. No account required.
THE GAP
Most tools stop at the script.
Writing apps end at a PDF. Boards live in another app, timing lives in a spreadsheet, and the editor starts from scratch. When AI can generate a shot in minutes, the bottleneck isn't making images. It's keeping story, timing, and intent connected all the way to the cut.
ONE PROJECT · FIVE VIEWS
One project. Every stage connected.
01Outline
Shape the story in beats and see estimated runtime as you plan.
02Script
Write in screenplay format; review each scene’s estimated screen time in Outline.
03Shot
Break scenes into shots linked to their source script elements.
04Boards
Build board frames from linked shots and set their durations.
05Edit
Play timed boards. Export a timed sequence that opens in Premiere Pro or Final Cut Pro, ready for real footage and sound.
Scene identity carries through every view. The export contains timing placeholders, not media.
WHY IT'S DIFFERENT
Plan with the cut in mind.
Hands off, doesn't lock in
ScreenplayOS prepares timing guides for other tools. The current exports contain placeholders, so footage and sound remain in your editor.
Your work stays yours
Projects live on your Mac. Writing, outlining, and supported exports need no account or internet. AI is optional, invoked by you, with your provider key in the macOS Keychain. When you use AI, you choose the service and see exactly what is sent before anything leaves your Mac.
WHO IT'S FOR
Built for the new production team.
For writers, directors, and producers making film, series, and animation, especially small teams working with AI-assisted pipelines, where one person may write the scene, plan the coverage, and cut the sequence.
COMING NEXT
What we're building next
- Continuity bible: characters, locations and style carried into every generation, so faces and places hold across shots
- Generation into shots: images, video and temp voice made with the AI services you choose, landing directly in each shot's timeline slot
- Consent built in: likeness and voice generation for real performers requires a recorded consent
- Temp voice, music, and effects lanes in the animatic
- Takes for generated or filmed clips within each shot
- Handoff to DaVinci Resolve, Premiere Pro, and Final Cut Pro, with edits returning as reviewable changes
