3 Easy Steps to Start
How to Use Voice Preview
Enable MCP & Set Prompt
Turn on the MCP feature and register the dedicated prompt.
Command Your AI as Usual
Instruct your AI in Cursor or VSCode to create specs or write code.
Auto-Audio Playback

Designed for Your Peace of Mind
Voice Preview is built specifically to reduce the burden of reading. Our architecture ensures that your data is neither stored nor used for training.
Zero AI Training
Voice Preview only processes text from your AI agents (such as Cursor, GitHub Copilot, etc.) to generate audio. We never collect or use your code or conversations to train our models.
No Data Retention
Text data is never stored for training or any other purposes. Once the audio is generated, the processed content is immediately discarded and not accumulated.
Secure Data Transmission
Data is transmitted to our servers over a secure connection only during the audio generation process. We do not save the transmitted text. To ensure service reliability, we maintain minimal communication logs (e.g., timestamps, success/error rates, and usage metrics), which do not include your actual content.
