AI scene partner app:
run lines alone, get every line scored
MasteringTheatre is a mobile app for actors (Android and iOS). It reads the other characters' lines out loud, listens to yours, gives each line a % score and shows a colour-coded word-by-word review at the end. It does not film you and never interrupts you mid-scene.
How it works
Three steps to turn your phone into a rehearsal partner.
Import your script
Paste your scene, import a file, or take a photo. The AI automatically detects characters.
Pick your role
Select the character you play. Other roles are performed by AI with distinct voices.
Rehearse!
The AI gives you the cue, listens to your line, gives you a score after every line and a word-by-word review at the end of the session.
