Pricing
- Pricing model
- 100% Free
The Local tier is free forever with no account: cloning across every TTS engine, dictation and capture, MCP and agent integration and unlimited local generations. A Cloud backup-and-sync tier is listed at $12 a year as a launch price and Studio at $48 a year, but both are marked coming soon and the page says cloud pricing and limits are not final.
Use tool ↗About Voicebox
Voicebox is a downloadable app that keeps voice work off the cloud. It clones a voice from a short sample, generates speech through seven text-to-speech engines, transcribes with Whisper, and dictates into any application on the machine. A stories editor arranges multi-voice narration on a timeline, and an effects chain adds pitch shift, reverb, delay and compression with saveable per-voice presets. Inference runs locally on Metal, CUDA, ROCm, Intel Arc or DirectML, or against a remote machine you control. An MCP server exposes it to agents. It is MIT-licensed and published by Spacedrive Technology Inc., the team behind the Spacedrive file manager.

Pros & cons of Voicebox
The most complete local alternative to the paid voice services: seven TTS engines, Whisper transcription, system-wide dictation and a multi-voice timeline editor, all MIT-licensed and running on your own GPU with no account. The costs are the ones local inference always carries — model downloads, GPU requirements and setup — plus a crypto token attached to the project that has nothing to do with using the app.
Pros
- Cloning, seven TTS engines, Whisper transcription and dictation in one free app
- Runs locally on Metal, CUDA, ROCm, Intel Arc or DirectML, or against your own remote box
- Timeline stories editor and a saveable audio effects chain for multi-voice work
- MCP server lets agents drive it, and generation runs to 50,000 characters at a time
- MIT-licensed with builds for macOS, Windows and Linux
Cons
- Quality and speed depend entirely on your own hardware
- Cloud backup and sync is still unreleased, so there is no sync between machines yet
- Setup means downloading models and picking an engine rather than opening a tab
- The project promotes a Solana token, which is noise around an otherwise clean open-source tool
Best for
- Voice work that must not leave the machine for privacy or contract reasons
- People who dictate all day and object to a per-seat subscription
- Creators assembling multi-voice narration without per-character billing
Not for
- Users on light hardware with no usable GPU
- Teams wanting a hosted service with SLAs and shared assets
Watch out: The bundled voice library is stocked with presets styled on real public figures; cloning an identifiable person's voice without consent is a legal problem in many jurisdictions regardless of what the app allows.
