What it does
Everything you need between casting and curtain-up
Built around the way actors actually learn lines — not the way software usually wants you to.
Hide your lines
Blank out your character's lines and cue yourself through the scene, revealing each one only when you've had a proper go at it.
Rehearse out loud
Speak your lines and have them checked against the script with voice recognition, so you're learning them the way you'll perform them.
Confidence scoring
Every run is scored, so you can see at a glance which scenes are solid and which ones still need another pass before you're in the room.
Productions & characters
Keep every show you're in side by side, each with its own cast list, scenes and the character you're actually playing.
Share with the cast
Send a prepared script to the rest of the company as an .offbook file, so nobody has to type the same scene twice.
How it works
Script in your hand to off book in three moves
Get the script in
Point your camera at the page, or import the PDF the director emailed you. OffBook reads it, splits it into lines, and asks which character is yours.
Run the scene
Your lines are hidden; everyone else's are there to cue you. Say yours aloud and OffBook checks them, or tap to reveal when you're stuck.
Watch it stick
Each run leaves a confidence score behind. Come back tomorrow, run it again, and see the line climb — that's the bit that tells you you're ready.
Confidence scoring
Stop guessing whether you know it
"I think I'm fine on Act Two" is not a plan. OffBook scores every rehearsal run and keeps the history, so the question stops being a feeling and starts being a number you can act on.
Weak scenes surface themselves. You spend your twenty minutes on the pages that actually need it, instead of running the opening you already nailed a week ago.

Confidence scoring and statistics are Pro features.
Yours, and only yours
An unreleased script is not our business
No account. No ads. No tracking. Your productions and rehearsal history live on your device.
No sign-up, ever
There's no account to make and no email to hand over. Open the app and start working.
Stored on your device
Scripts, characters, rehearsal history and confidence scores stay in local storage on your phone.
Honest about the exceptions
AI import and voice recognition do send content to Google or Apple to be processed. We spell out exactly what and when.
I built OffBook because I kept losing the pages of my script on the bus, and because no app I tried could tell me whether I actually knew Act Two or just felt like I did. Alex Brent — developer, and occasional am-dram cast member
