Read with lines hidden
Your character's lines are blanked out; everyone else's stay visible as cues. Tap a hidden line to check yourself, and keep moving.

Four ways to get a script in
Whatever form your script arrived in — a photocopied stack from the director, a PDF in your inbox, or a Word file passed round the group chat — it can go straight into OffBook.
- — Camera scan. Photograph the pages and OffBook lifts the text off them.
- — PDF. Import the file the production sent you, as it is.
- — Word or plain text. DOCX and TXT both come straight in.
- — Typed by hand. For a monologue or a single scene, sometimes it's quickest.
Camera and document imports use Google's Gemini AI to read the pages and lay them out as dialogue — that gives the most accurate result, and it means the content of that import is sent to Google. Plain text and manual entry never leave your device. It's all set out in the privacy policy.

02 — Rehearse
Three ways to run a scene
Because learning lines on the sofa and running them the night before opening are not the same job.
Say them out loud
Speak your line and OffBook listens, checking what you said against what's written. Rehearsing aloud is what makes it stick.
Work a single scene
Don't run the whole play to fix one exchange. Pick the scene that's wobbling and drill just that until it's solid.
On voice recognition: on Android this goes through Google's speech recognition service; on iOS it uses Apple's Speech framework, which works on-device when you're offline where your device supports it. OffBook never keeps the audio — it's checked in the moment and gone.
Where you stand today
Confidence by scene
03 — Track
A number instead of a feeling
Every run you do is scored and kept. Over a week that turns into a picture of which scenes are safe and which one is quietly going to catch you out at the tech run.
It changes how you use your rehearsal time. Twenty minutes on the scene at 38% is worth more than an hour on the one you've already got.
Confidence scoring and the full statistics history are Pro features, with a free trial so you can see them working before you buy.
04 — Organise & share
One app for every show you're in
Productions
Each show kept separately, with its own script, scenes and cast.
Characters
Tell OffBook who you're playing and it knows which lines to hide.
Session history
Every run you've done, kept so you can see the trend rather than the last go.
Shareable files
Export a prepared script as an .offbook file and send it to the rest of the cast.
Practical bits
The things people ask before downloading
Does it work offline?
Mostly, yes. Storing scripts, hiding lines and running scenes all work with no connection at all. AI script import and camera scanning need the internet for the best results, and fall back to on-device text extraction when you're offline. Voice recognition depends on your platform — see the note above.
Is it on both iOS and Android?
Yes — OffBook is on the App Store and Google Play, and the feature set is the same on both. A few things are handled differently underneath, mainly speech recognition, because each platform provides its own.
Do my scripts sync between devices?
Not currently. Script and rehearsal data is stored locally on each device. Your Pro unlock does follow your Apple ID or Google account across devices, and you can move a script yourself by exporting it as an .offbook file.
What does it cost?
The app is free to download and the core rehearsal features are free to use. Pro is a one-off purchase — not a subscription — and there's a free trial of the Pro features first. See what's in Pro.
Try it on your own script
It takes about a minute to import a scene and start running it.
