How it works

Scene 01

Drop in your sides

Paste the scene or add a PDF or TXT. Sidesly finds the characters, splits the dialogue and mutes stage directions.

Choose who you play. Every other character gets a reader voice, and you can fix any line the parser got wrong.

Scene 03

Say your lines

The reader speaks the cue, listens for you, and moves on when you pause. Tap "I'm done" any time to hand it over yourself.

Watch a read-through

The reader speaks. You answer. It listens.

Field notes

How memorize lines fits your prep

A cognitive approach to memorizing lines

Staring silently at printed sides engages only visual memory, which often crumbles under audition pressure. To truly memorize lines, actors must hear cue triggers and speak responses out loud. Sidesly turns passive script reading into active auditory rehearsal. By vocalizing incoming cues and pausing for your spoken line, the system cements acoustic anchors in your memory so lines flow naturally when the red record light turns on.

Accelerating your line rehearsal workflow

Whether you have twenty pages of episodic television sides or a tight two-hander scene, repetition is the foundation of confidence. You can loop specific scenes, drill troublesome dialogue beats, or transition directly into full self tape reader run-throughs once the lines stick. If you are preparing solo performance pieces, you can also transition your cues into monologue practice to polish cadence without cue dependency.

Complementing your acting community

Working with human scene partners is the heart of dramatic art. Sidesly is designed as a tireless study partner for the grueling early phases of learning lines, saving your friends and coaches for artistic notes and chemistry adjustments. Think of Sidesly as an acoustic flashcard partner: it handles the repetitive drill work so your live sessions with human partners remain fresh and creatively stimulating.

Step-by-step cue drill guide

Import your sides via text or PDF file. Our parser isolates your character from the dialogue while muting stage directions. Choose whether you want full text visibility or blurred lines to test your recall. As the AI vocalizes your partner's cue, deliver your response out loud; our speech detection verifies your completion before advancing, providing a tactile, hands-free drill experience through our dedicated line reader for actors.

FAQ

Questions actors ask

Why is speaking lines out loud better than reading silently?

Auditory and muscular memory reinforce each other. Speaking lines out loud trains the mouth, vocal cords, and breath control to automatically produce words under high audition stress.

Can I hide my character's lines while drilling?

Yes. Sidesly provides a recall mode where you can blur or obscure your upcoming lines, forcing your brain to retrieve words purely from hearing your partner's cue.

Does Sidesly support scene loops for difficult pages?

Yes. You can select any scene or range of lines and loop them continuously until the dialogue feels like second nature.

How long does it take to get off-book with Sidesly?

Most actors report cutting memorization time in half because active cue-and-response drilling eliminates the downtime of flipping pages or waiting on someone else's schedule.
