Stentor Download

Write it. [pause 0.5] Hear it in your voice.

Stentor turns your scripts into voiceovers in your own voice, with AI that runs entirely on your Mac. Moods, pauses and sounds are part of what you write, and every word is checked before you hear it.

For Macs with Apple silicon (M1 or newer).

Local AI. Your Mac does the work.

The voice, the word check and the clean-up all run on your Mac's own chip, with open models you download once. No cloud in between, no per-minute pricing, and nothing uploaded while it voices.

0
Bytes sent to a server when it voices. Your scripts and recordings stay on your Mac.
Offline
After the first download, voicing works with no internet connection at all.
No meter
No credits and nothing counting. Voice the same script as often as you like.
Open
Open models with open licences: Chatterbox, Whisper and Maya2.

The editor is the studio.

Everything happens in one place: you write the script, mark how it should sound, voice it, check it, fix it and export it.

3 Mac settings that feel brand newVoice it again

[happy] Hey everyone, welcome back to the channel! [pause 0.5] Today I'm showing you three settings that make your Mac feel brand new.

[surprised] And here's the one nobody talks about. @sur

Pick the voice, the model and the delivery.

The side panel holds everything about how it's read. The model list follows the script's language, so you only see models that can speak it.

  • On your Mac: Chatterbox Turbo for speed and every symbol, Standard for stronger emotion.
  • ElevenLabs, if you want it: their models, with your own key and credits.
  • Delivery: how lively each take is, pauses between sentences and paragraphs, loudness.

Any language, found for you

The script's language is detected as you write. A script can even mix languages; each sentence is voiced in its own.

Translate a whole script

Your assistant writes it in another language, for speaking, as a new script. Symbols, names and brands stay.

Every version kept

Each round of editing is saved. Compare an older version, or bring it back.

Export for your video editor

WAV or MP3 levelled for YouTube, SRT captions timed to your voice, word timings for animations, and the script.

Your voice, with consent

Clone your voice in about two minutes. You say a consent line with a fresh code each time, and Stentor checks it's really you.

Hear it as you read it

Words light up as they're spoken. Change the playback speed, or click any word to start there.

Runs on your Mac. Connects to what you already use.

The voicing is open models on your Mac: download what you need once, in the app, and it works offline after that. Connect your own accounts when you want more. Stentor never resells anything or stands in between.

Your scripts and your voice stay yours.

It runs on your Mac

Voicing, the word check and clean-up happen on your Mac, offline. The optional tools only see what you send them: Enhance sends the script's text to your assistant, ElevenLabs the text it voices.

No voice without consent

Cloning starts with a live consent line and a new code each time, then a check that the voice matches the person saying it.

Your tools, your accounts

Claude Code, Codex and ElevenLabs are optional and use your own plan or key, kept in your Mac's Keychain.

Questions

Still wondering about something? There's more in Help, or write to support@getstentor.com.

Is there a cost per voiceover?

Not on your Mac: voice the same script as often as you like. ElevenLabs, Claude and ChatGPT plans are your own, and billed by them.

Do my scripts and recordings leave my Mac?

No. Voicing happens on your Mac, and your scripts, recordings, voices and voiceovers are stored there. Text only leaves when you choose: to Anthropic or OpenAI when you use Enhance, Fix how it's said or Translate with your own plan, and to ElevenLabs when you voice with an ElevenLabs voice. Privacy

Does it work offline?

Yes, once the voice models are downloaded. Only the writing assistants and ElevenLabs need the internet.

Whose voice can I clone?

Your own, or the voice of someone who is with you and says the consent line themselves. Each consent line has a fresh code, and Stentor checks it's the same voice that then reads the text.

Which languages can it speak?

English with the basic setup. Add Chatterbox Multilingual for Spanish, Arabic, French, German and 17 more, or Maya2 for Hindi, Tamil and 9 more Indian languages. A script can mix languages: each sentence is voiced in its own. ElevenLabs voices speak more.

Do I need Claude or ChatGPT?

No. They power Enhance, Fix how it's said and Translate, with your own plan. Writing, voicing, checking every word and exporting all work without them.

Can I use my voiceovers in monetised videos?

Yes, they're yours, within the terms (above all: only voices you have consent for) and the licences of the models you use.
