Sidesly

Sidesly is an AI line reader for film, television, and theatre actors preparing auditions and self-tapes. Upload PDF or TXT sides, choose your role, and rehearse out loud while AI reads the other characters. Responsive cue detection listens for natural pauses and advances the scene. Practice with five modes: Self Tape Reader, Memorize Lines, Cold Read Practice, Monologue Practice, and Teleprompter for Actors. It runs in desktop and mobile browsers with no app to install. Scripts stay private and are not used to train models. The limited free trial includes 1 script and 5 minutes of audio generation, with no credit card required; paid plans are available. Sidesly is a rehearsal backup when nobody is available to read, not a replacement for human scene partners.
