Chatterbox is Resemble AI's open-source text-to-speech model, offering zero-shot voice cloning from a few seconds of audio, emotion control and real-time generation across a couple of dozen languages. Unusually for a model from a company whose product is a hosted voice API, it is MIT licensed and runs on your own hardware, so the audio never has to reach the vendor. Paralinguistic tags such as laugh and whisper are supported.

Why this trust score (87/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 25/25: No cloud key is needed at all. The model runs locally.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under MIT, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

Key handling varies. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Add your provider API key in settings and choose a model.
