Audiobook Studio 2.0 docsCloud Engines (e.g. Voxtral)
Cloud engines are optional. You enable one with an API key; none ship or run by default. Voxtral (Mistral-hosted) is one example.
At a glance
- Optional and opt-in: off until you enable one.
- Enabled with an API key.
- Some data leaves your machine when used.
- Voxtral is one example of this kind of engine.
Enabling a cloud engine with an API key
Add the provider's API key in Settings to enable it. Until a key is present, the engine stays hidden. Voxtral, for example, is enabled with a Mistral API key.
What data leaves your machine
Using a cloud engine sends the text to be spoken (and any required reference audio) to the provider. Studio discloses this clearly. See Local-First & Privacy.
Heads up: a cloud engine means data leaves your device. Review the provider's terms; Studio shows facts, it doesn't act as a legal gate.
When to use one
Use a cloud engine when you want a voice or model it offers. You never need one; the local engine can do a whole book.
