Sidesly is an AI line reader for film, television and theatre actors preparing auditions, self-tapes, cold reads and monologues. Upload PDF or TXT sides up to 20 pages, choose your role, and run lines aloud with responsive AI cue partners that listen and advance when you pause. Five modes cover Self Tape Reader, Memorize Lines, Cold Read Practice, Monologue Practice and Teleprompter for Actors. It works in a mobile or desktop browser without installing an app. Scripts stay private and are not used to train models. Free trial, with paid monthly and annual plans.
Actors need to run lines out loud even when nobody is available to read with them. Sidesly provides a responsive rehearsal backup for audition sides and self-tapes, without replacing human scene partners or chemistry reads.
