A Counterpart alternative on Mac or Windows

Why Offbook is the stronger choice

Works on Windows too

Offbook runs in a laptop or desktop browser, Mac or Windows, with the full script on a big screen. There is nothing to install.

Nothing to record

AI voices read every other character as soon as your script is uploaded. You choose a voice for each role, and you can change the speed of any line.

It follows your whole line

Offbook listens while you speak and plays the next cue when you finish. Strict mode keeps you close to the script, so small word changes do not turn into habits.

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.

Who Offbook is for

Offbook is the better pick for most actors. Choose Offbook over Counterpart if you:

Rehearse on a Windows laptop or any computer with a browser
Do not want to record the other parts yourself
Want the full script on a big screen while you rehearse

How Offbook works

Upload your script. Add a full script or audition sides as a PDF, photos of the pages, or pasted text. Offbook finds the characters for you.
Pick your role. Choose who you play. AI voices read every other character, and you can pick the voice for each role.
Rehearse or self-tape. Say your line out loud. Offbook hears you finish and plays the next cue.
