Why Offbook is the stronger choice

The full script on a big screen

Rehearse in a laptop or desktop browser, Mac or Windows, and see the whole scene while you work. Then listen to your scenes on your phone anywhere, with your own lines spoken, skipped, or left as silent gaps.

Full plays, not only sides

One scene holds up to 50 pages, and the page picker splits up to 150 pages into scenes, so a full-length play fits.

Choose how exact you need to be

Strict mode keeps you close to the script, Lenient mode forgives paraphrasing with a 0-100 slider, and Manual mode lets you move on yourself with Enter or by saying “next line.”

A coach that has read your scene

Ask Genie about your character’s motivation, the scene, or how to read a line. Highlight text for an answer about that exact moment.

Rehearse with your cast

Share a scene by email invitation on any paid plan, or by public link on Pro and Premium. Castmates with a free account can practice a scene you share with them.
