For Actors
AI Scene Partner for Actors
Last updated September 2026
Upload your sides, pick your role, and the AI reads every other character with emotion. It listens while you speak and waits for you, so you can run the whole scene with no reader in the room.
How it works
Upload your sides
Drop in a PDF or a photo of your script. Line Echo reads the characters, dialogue, and emotion automatically, including photographed and watermarked casting sides.
Pick your character
Choose who you are playing. The AI takes every other role and reads each line with the emotion the scene calls for.
Rehearse out loud
Say your lines. It listens, waits for your cue, and continues when you are done. Run the scene as many times as you need.
What it does well
It waits for your cue
It listens while you speak and continues when you finish, instead of running on a fixed timer. You practice cue-response, the reflex the audition actually tests.
Emotion-aware delivery
Every line is analyzed for sentiment, so an angry line sounds angry and a tender one sounds tender. You respond to real emotional cues, not a flat read.
Works in any browser
No app to install. It runs in the browser on desktop, iPhone, and Android, so you can rehearse on whatever device is in your hand.
Speech recognition on your device
The speech recognition that matches your words runs entirely on your device. What you say is never uploaded.
Where it falls short
An AI scene partner is not a human one. It will not improvise, and it will not give you the notes a coach or a live reader would: it cannot tell you a choice is not landing or surprise you with a reading that changes how you see the scene. Its reads are consistent, where a person's vary from take to take.
Think of it as the tool for the prep reps: memorizing, drilling your cues, and running the scene until it lives in your body. A live partner covers the rest. For the full picture, read how to rehearse lines with AI and where it falls short.

Frequently asked questions
Do I need a scene partner or a reader?
No. Line Echo is the AI scene partner. It voices every other character in your scene, listens while you say your lines, and waits for your cue, so you can rehearse the full scene alone.
What does the free plan include?
The Audition plan is free forever with 2 active scripts, 3 uploads a month, and up to 50 lines per script, using standard AI voices. The Working Actor plan at $19/mo unlocks unlimited scripts, more uploads, and premium voices.
Which browsers and devices work?
It runs in any modern browser on desktop, iPhone, and Android. There is nothing to install.
Does it record me?
No. The speech recognition that checks your lines runs on your device and what you say is never uploaded or stored.
Is my script private?
Your script is stored privately in your account. It is processed by our AI providers only to read the scene and generate the voices, and we never sell it or use it to train AI models.
