A screenwriting tool built for writers.
Industry-standard formatting, offline-first, and nothing in your way.
Built for the craft
Every scene heading, action line, and dialogue block exactly where it belongs.
Bring in FDX, DOCX, or plain text. Your existing work comes with you.
Share the way producers expect. One-click exports in every format that matters.
Branch freely. Snapshot any version and come back to it anytime. No version anxiety.
Your data lives on your device, not in the cloud. Works offline. Always yours.
No dashboards. No onboarding tours. No friction. Just sit down and write.
OpenSlug stores everything locally on your device. No account. No server. No subscription. Your work is never uploaded anywhere unless you choose to share it.
Stored on your device
Scripts live in your browser's local storage — no cloud sync, no data collection.
Works completely offline
No internet? No problem. Open the app and keep writing anywhere.
Private by default
We never see your writing. Zero telemetry. Zero tracking.
Familiar from day one
FADE IN:
INT. SMALL APARTMENT - NIGHT
A cluttered desk. Coffee mug. Half-crumpled notes.
JOHN (40s) opens a blank document. The cursor blinks. Outside, the world demands attention. In here...
...there is nothing but the page.
He exhales, cracks his knuckles, and starts typing.
JOHN
Let's do this
He begins to type. The words come slowly, then all at once. Like a faucet turned on full blast, the story just pours out.
JOHN (CONT'D)
(muttering, surprised)
Okay… yeah. This is actually working.
He keeps going. The cursor never stops moving.
The page is no longer blank. It is full of possibility.
FADE TO:
No sign-up. No tutorial. No friction.
Just open it and start writing.
