Never be off book again. LineRunner turns any script into a live rehearsal with AI scene partners — every other character is read aloud in a distinct voice while you run your lines. REHEARSE ANY SCRIPT • Browse the free Script Library of classic public-domain plays and add them to your Repertoire • Or upload your own script as a PDF — LineRunner parses it into characters, scenes, and lines automatically • You see the parsed result (title, cast size, line count) before you pay anything AI SCENE PARTNERS • 13 distinct, natural voices play every character except yours • Voices are auto-matched to each role using cues from the script itself • Tap to hear your own line whenever you need a refresher PRACTICE LIKE AN ACTOR • Step through scenes at your own pace — the app waits for you • Reveal your next line word by word, or all at once • Start rehearsal from any line in the script • Your place and progress are saved automatically SIMPLE PRICING • The Script Library is free • Uploading your own script is a one-time $2.99 purchase per script — charged only after the parse succeeds • No subscription. No account. No ads. Made for actors, drama students, directors, and anyone who has to learn lines. Questions or feedback: support@linerunner.app
