Stentor

Terms of use

Last updated 5 November 2026

These terms cover the Stentor app and this website, made by Stentor ("we"). By using them, you agree to these terms. They're written to be read; if anything is unclear, ask us at [email protected].

1. Voices: only with consent

Stentor can make a voice that sounds like a real person. That carries responsibility, so these rules matter most:

  • Clone only your own voice, or the voice of someone who is present, says the consent line themselves and agrees to it.
  • Don't use a voice to pretend to be someone, to mislead people about who is speaking, or to make someone appear to say something they didn't.
  • Don't use it for fraud, scams, harassment, defamation, or anything illegal, including deceiving people in elections or getting past voice-based security.
  • If your work could be mistaken for a real person speaking, say that it's AI-made where your platform or the law asks you to (for example, YouTube's disclosure for realistic altered content).

The app asks for a recorded consent line with a fresh code, and checks that the line was said. These checks help, but you're responsible for how you use any voice.

2. What you make is yours

Your scripts, recordings and voiceovers belong to you. You can use your voiceovers commercially, for example in monetised videos, as long as you follow these terms, the licences of the models you used, and the terms of any service you connected (like ElevenLabs). We don't claim any rights over what you make.

Voiceovers made with Chatterbox models carry an inaudible watermark added by the model, which marks the audio as AI-made. Don't try to remove it.

3. The trial and your licence

  • Trial: every feature is free for 14 days from the first time you open Stentor on a computer. After that, Stentor needs a licence to keep working; your scripts and voices stay on your computer.
  • Licence: one licence is for one person on one computer at a time. You can move it to another computer from Settings › Licence. Don't share, sell or publish your licence key.
  • Checks: Stentor checks the licence online now and then. Offline, it keeps working for up to 3 days in the first 14 days after you activate it, and up to 60 days after that; then it asks to connect once.
  • Don't get around it: changing the app, its licence check or its trial, or using a cracked copy, isn't allowed. A changed copy of Stentor won't run.

4. Buying and refunds

Payments are handled by Razorpay, our payment provider, under their terms. You'll get a receipt and your licence key by email. You can ask for a refund within 7 days of buying by writing to [email protected]. A refunded licence stops working.

5. Models and other services

The voice models are made by others and come with their own licences (for example MIT or Apache 2.0, and CC BY 4.0 for Kyutai's Mimi codec). When you download one, its licence applies. Claude Code, Codex, ElevenLabs and Hugging Face are separate services: you use them with your own accounts, under their terms, and pay them directly if they charge.

6. The software

Stentor is still young: it may have bugs, and things may change. We'll announce changes that affect you on this site and in the app before they happen. The app's name, logo and software remain ours: your licence lets you use Stentor, not resell or redistribute it.

7. No warranty

Stentor is provided "as is", without warranties of any kind. AI voices can mispronounce words, and the word check can miss mistakes: listen to your voiceover before you publish it. Keep backups of anything important.

8. Limits of liability

To the extent the law allows, we aren't liable for indirect or consequential losses, lost data or lost income arising from using Stentor, and our total liability is limited to what you paid us in the past 12 months. Nothing here limits liability that can't be limited by law.

9. Ending

You can stop using Stentor at any time by deleting it. We may stop providing it, or end the licence of anyone who breaks these terms, especially the rules in sections 1 and 3.

10. Changes

We may update these terms. We'll change the date at the top, and announce important changes on this site and in the app's release notes before they take effect.
