Run lines out loud. Any hour.

Learning lines in your head is the slowest way to do it. You know the scene until the moment someone says the cue at a speed you did not expect, and it evaporates. Lines live in your mouth and your ears, which means running them out loud, on cue, over and over.

That normally needs a person. This is the version that does not.

Drop the sides in exactly as they came

Audition sides arrive as a PDF with casting's marks all over them: START and END brackets, FYI sections that are context only, scribbles in the margin, sometimes a watermark across the middle. Subtext reads the document as it is, lifts out the marked scenes, works out who says what, and hands you a rehearsal. No retyping, no setup screen, no pasting lines into a form.

It works on a full script too, which matters the day the whole thing lands.

A voice that acts, not a robot reading

Every other character is read by a voice that performs the line. It rages, it breaks, it whispers, it lands the sarcasm. That matters more than it sounds: you cannot rehearse a reaction to a flat line, because there is nothing to react to.

You can cast the parts yourself if you have a picture of the character in your head, or let it cast them and press play.

It listens while you talk

You say your line out loud and it waits for you, then comes back in on cue. Fumble a word and the scene does not stop. Paraphrase and it follows. That is the whole point of running lines with someone: the scene keeps moving, and you learn where the pressure is.

Off book, a word at a time

When you are ready to stop reading, your lines hide. Get stuck and it reveals one word, then the next, so you are recalling rather than reading. Run the same scene until the prompts stop coming.

Then leave the pages behind entirely: press play on a full table read and hear the whole thing performed on the drive in, or lock the script in rehearse mode and take it to the room.

When you want a person instead

Sometimes you do not want to drill, you want to play the scene with someone. Text a friend a link and they record their side in their browser, once. Their real voice then reads opposite you in every run and on every take, without either of you scheduling anything.

Then know what you are actually saying

Being off book is the floor, not the ceiling. The next question is what the scene is about, what your character wants, and what happened before the page starts. That is script analysis, and it is in the same app.

Questions actors ask

Can I run lines without another person?

Yes. Subtext reads every other part out loud, performed, and listens while you say yours. It is built for rehearsing alone at whatever hour you are free.

Does it work with audition sides, not just full scripts?

Yes, and sides are the common case. It reads casting's START and END marks, skips FYI sections that are context only, and copes with scribbles and watermarks.

Will it help me memorize, or does it just read at me?

It drills you. Your lines can hide completely so you are recalling rather than reading, with one word revealed at a time when you are stuck, and you can run the same scene as many times as it takes.

Can I hear the whole script performed?

Yes. A table read plays the entire script with every character voiced, and it keeps playing with the phone locked, so you can listen on a jog or on the drive in.

What do I need to run it?

An iPhone or an iPad, on iOS 17 or later. Scripts and notes sync between your own devices.
