We never train AI on your scripts
Offbook does not use your scripts, scenes, or lines to train AI models.

Your scripts live in your own library. Other Offbook users see a scene only if you share it, and you can stop sharing at any time.
We never sell your scripts
We do not sell your scripts or your personal information, and we never publish your script text or titles.
Encrypted in transit and at rest
Your scripts travel over encrypted connections and are stored encrypted by our cloud providers.

Offbook is transforming how actors prepare for their roles, enabling faster memorization and deeper character work across theater and film.
“This saved my finals. I was running lines on this app at 2AM so I could practice my three scenes as many times as I needed.”
Drama Student • Fordham University
“My new line-learning process is simple, get my sides, pop them into Offbook, drill. No more bugging my friends to read for me.”
Film & TV Actor • Los Angeles
“You can clearly see in the quality of the application that it was built by actors who know what they're doing. Very detailed and useful. I really like it.”
Stage Performer • New York City
“I like that Offbook never gets frustrated when I need to repeat sections over and over. I can actually focus on my delivery.”
Film & TV Actor • Chicago
“Started using this for my conservatory work. I really like the chat feature where I can validate my script analysis and get a second opinion.”
Theater Graduate • DePaul University
“Got sides last minute while I was traveling. I didn't have anyone to run with, so I rehearsed on the app in my hotel room. By the end, I felt ready to tape.”

Questions actors ask
About line learning apps, AI scene partners, and how Offbook works.
What is a line learning app?
A line learning app helps you memorize a script by running it with you. Offbook is a line learning app for actors: upload your script, choose your role, and AI voices read every other character. Offbook listens through your microphone, plays the next cue when you finish your line, and lets you hide your lines step by step until you are off book.
How do I choose a learn lines app?
Check four things. Does it start from the script you already have? Does it wait for you to finish your line, or play on a timer? Can it take your lines away in stages? Where can you use it? Offbook reads a PDF, a photo of the pages, or a text file, listens for your line, and has hidden lines and first-letter cues. Our guide to the best line learning apps compares the main options side by side.
Is Offbook a rehearsal app for actors?
Yes. Offbook is a rehearsal app for actors who want to run scenes out loud without waiting for a partner to be free. Beyond running lines, you can change the playback speed of any line, add pauses, loop the scene, read from a teleprompter that highlights each word as you say it, and ask Genie, the script assistant, about motivation and subtext. On a paid plan you can also share a scene with a castmate.
What is an AI scene partner?
It is software that reads the other characters’ lines aloud and waits for yours, so you can rehearse a scene alone. In Offbook, AI voices read every role except yours. If you need a moment, it waits; if you go up, say “next line” or press Enter to move on. Here is how our AI scene partner works.
Is there a free line reader I can try first?
Yes. Our free run lines online tool lets you rehearse classic scenes in Offbook’s voices and waits for your line. Our free line memorizer turns your lines into first-letter cues. Neither needs an account. When you want AI voices, script upload, and a reader that listens for you, use the Offbook line reader app. Every plan starts with a 7-day free trial.
Does Offbook work on a phone?
Yes. Rehearse on your laptop with the full script on a big screen, and listen to your scenes on your phone anywhere. Rehearsing out loud with cues works in a laptop or desktop browser, Mac or Windows. An iPhone app is coming soon.
What does Offbook cost after the free trial?
Every plan starts with a 7-day free trial, and a card is required. After the trial, Starter is $9.99/mo, Pro is $14.99/mo, and Premium is $29.99/mo. Annual billing starts at $7.99/mo, and students and educators get 50% off with a valid .edu email.
