Free Apps That Read the Other Lines for Actors (2026)

The Short Answer

Yes, some apps read the other characters' lines back to you for free. Line Echo's free plan does it with AI voices, Script Rehearser and Scene Partner do it with your device's text-to-speech, and ActOnCue lets you run lines free in the browser. The catch is always in the limits, so the tables and notes below spell out exactly what each free plan includes.

Full disclosure: we build Line Echo. This is a vendor roundup, so read it as one. Every free plan below is described from the app's own site or store listing as of September 2026, with the limits stated plainly.

At a Glance

Prices and limits checked September 2026.

Line Echo - Free AI voices that read the other roles

Line Echo is a browser-based AI scene partner with a free plan, best for actors who want the other characters voiced with AI at no cost. The free Audition plan includes 2 active scripts, 3 uploads a month, 50 lines per script, and 150 new AI voice lines a month on standard voices, with unlimited replays of lines you've already heard and no credit card. It reads every character you are not playing, listens through your mic, and waits for you to finish. There is also a free scene library you can rehearse with no account at all.

Choose it if: you want AI voices reading the other roles for free and a partner that actually listens.

Skip it if: you need premium voices or heavy monthly volume; those are on the paid plans.

Script Rehearser - Free, using your device's voice

Script Rehearser is a free line-rehearsal app, best for actors who just want the script read aloud at no cost. It is free with optional in-app purchases, and it uses your device's built-in text-to-speech for the lines you have not recorded yourself. It imports PDF and plain text, and it advances after a timed gap for your line rather than listening for your cue.

Choose it if: you want a genuinely free reader and device text-to-speech is good enough.

Skip it if: you want premium AI voices or a tool that listens for your cue. Full comparison.

Scene Partner - Fully free on Android

Scene Partner (by sam.robison) is a free, Android-only line runner, best for actors who want zero cost and no subscription at all. It auto-casts a distinct text-to-speech voice per character from a .txt or .docx script. You move through the scene with Next Cue and Previous Cue buttons rather than speech recognition, and it is still in active development.

Choose it if: you are on Android and want a completely free TTS reader with no account.

Skip it if: you want it to listen and advance on its own, or to import PDFs.

Linus - Free trial, then paid

Linus is an actor-built AI scene partner, best for actors happy to pay after a taste. Its free option is a trial, not an ongoing free tier: a single one-page scene of up to 10 lines. Within that, it reads the other roles with AI voices, listens, and waits for you, and the paid Pro plan is $9.99/mo. Treat the free part as a demo rather than a way to rehearse indefinitely.

Choose it if: you want to try full AI scene-partner rehearsal before buying.

Skip it if: you need to rehearse real scenes for free past 10 lines. Full comparison.

ActOnCue - Free line running in the browser

ActOnCue is a browser-first AI line reader, best for actors who want to start free without a subscription. Line running is free and unlimited on the site; the paid part is AI character voices and self-tape sessions, billed from a $19.99 top-up credit pack rather than monthly. So the free start covers running lines, while the richest AI voices sit behind credits.

Choose it if: you want to run lines free in the browser and pay only for extras you use.

Skip it if: you want full AI voices at no cost; those draw from paid credits.

Slatable - Free tier, but the reader is Premium

Slatable is a self-tape and audition app with a free tier, best for actors who mainly want free self-tape recording. The free plan allows one audition a month. Its AI reader that plays the other lines, "SceneAudio AI," and its auto-reader that listens for the next line are Premium features ($9.99/mo), so the free tier does not read the other roles aloud.

Choose it if: you want free self-tape recording and audition tracking, with the reader as a later upgrade.

Skip it if: you want the free plan itself to read the other lines; that needs Premium, and Slatable is iPhone-only.

What Free Usually Leaves Out

Free plans are real, but read the edges before you rely on one.

• Premium voices. Line Echo's free plan uses standard voices; the natural premium voices are on paid plans. Slatable's AI reader is Premium only. Free often means a plainer voice.
• Line and usage caps. Line Echo's free plan is 50 lines per script and 150 new AI voice lines a month, and replaying lines you've already heard is free, which is plenty for an audition but not a full play. Scene Partner and Script Rehearser lean on device text-to-speech, which has no AI cost but a flatter delivery.
• Trials that end. Linus's free option is a 10-line trial, not an ongoing tier. A trial is a demo; a free tier is something you can keep using.

The honest rule: a free tier you can rehearse on indefinitely (Line Echo, Script Rehearser, Scene Partner) is worth more than a short trial, and device text-to-speech is free but flatter than AI voices.

Frequently Asked Questions

Is there a truly free app that reads the other lines? Yes. Line Echo's free plan reads them with AI voices, and Script Rehearser and Scene Partner read them with your device's text-to-speech at no cost. Line Echo's free scene library also works with no account.

What is the catch with free readers? Usually the voice or the volume. Free plans lean on standard or device voices rather than premium AI ones, and they cap how much you can rehearse each month. A trial like Linus's 10-line demo ends, while a free tier keeps working.

Do I have to install anything? No. Line Echo and ActOnCue run in the browser on any device, and Line Echo's free tools need no signup. Script Rehearser and Scene Partner are app downloads.
