It listens to you, so you can listen to the scene. Line Run gives you your cue and waits for your response, so the words stick. Built for actors, by an actor.
Getting off book is the hardest part of the job. It usually happens in the living room: your script in one hand, the other covering your lines.
That's how I memorized for years, and it never came easily. I would read the other lines and recite mine, never really listening. The words didn't stick because I wasn't thinking the thoughts.
With Line Run, you hear the scene instead of reading it. It speaks the line before yours and listens while you respond, so you hear your cue and think your way into the reply. You're thinking the thoughts and connecting the dots, and this time the words stick.
RECORD IT, OR IMPORT IT
Record the other characters yourself, once. It's the more lifelike way: your own pacing, your own pauses, each part pitched up or down so they sound like different people.
Or let Line Run Pro do the work. Import your script and every other part gets a natural-sounding voice, made right on your phone.
One is more lifelike, the other is less effort. Either way, it sounds like a cast running the scene with you.
BUILT FOR ACTORS, BY AN ACTOR
Hi, I'm Kelly. I've been in this industry for over 25 years, and memorizing is still a challenge. I built Line Run so that we can get off book sooner, with confidence, and rehearsal can be about the acting.
SIMPLE TO START, DEEP WHEN YOU WANT IT
If you can press play, you can use Line Run. Open a scene and start talking. If you go blank, say "Line, please" and it prompts you. When you want more, it's all there: loop a tricky section, fine-tune the line text, mark it up with notes about motivation, hide the lines to suit your learning style.
PRIVATE BY DESIGN
There is no account and nothing to sign up for. There are no ads and your data will never be sold to anyone. Your recordings stay on your phone, and the generated voices are made there too, not in a data centre.
FREE FOREVER
Line Run is free forever, and it's a complete tool, not a trial. It has everything you need for an audition or a less demanding role: one script of up to three scenes, recorded in your own voice, with every way to rehearse.
LINE RUN PRO
Unlock everything in the app:
• Import your scripts, even scanned pages or sides
• Natural-sounding voices for every other character, generated automatically
• Unlimited scripts and scenes
I know how tough it is out there for actors to make ends meet, so I've priced this low to cover costs, not to profit. An annual subscription, with a free trial to start. Cancel anytime.
Generated voices need a one-time download of about 330 MB. On iPhone 11 and earlier, and the 2nd-generation iPhone SE, Line Run uses the phone's built-in voices instead.
