A scene partner that never gets tired and catches every flub. Load a script, pick your character, and run lines out loud -- it listens, flags mistakes, and rewinds to the trouble spots. Free, no signup, and we never receive your audio.

Line Runner runs in your browser. We never receive your audio, and your scripts stay on your device unless you choose to share a run. Here is exactly what happens to each kind of data:
Line Runner Pro (optional, paid) asks you to sign in with Google so your purchase follows you between devices. We store your email and what you bought. Stripe handles the payment, and we never see your card.
Sharing a run (Pro, optional) is the one time a script leaves this browser. When you tap Share, we save a copy of just the scenes in that run, plus how it went, so your coach or director can open the link. Nothing else from your library goes with it. Anyone with the link can read it, so send it only to people you trust. Links stop working after 30 days, and you can delete one sooner from Shared runs. Deleting removes the copy from our server.
None of this is sold, and under their API terms the AI providers do not use this text to train their models. Browser voices and tap mode use no outside services at all.
