VocalCode's answer:

Choose VocalCode if you want local recognition, simple push-to-talk input across Windows and Apple-silicon Mac, a 30-day full-function trial, and no recurring subscription. It is designed for AI coding prompts but works in most desktop text fields.

How would you describe the primary audience of your product?

VocalCode's answer:

Software developers and people who prompt AI coding agents such as Claude Code, Cursor, and Codex, especially those who prefer speaking longer prompts instead of typing them.

What's the story behind your product?

VocalCode's answer:

Daming Wu built VocalCode to make long AI-coding prompts faster to enter while keeping speech recognition local. The product focuses on one action: hold a configured key or mouse button, speak, release, and continue working in the current app.

Which are the primary technologies used for building your product?

VocalCode's answer:

VocalCode is a Rust desktop application with platform-native Windows and macOS integrations. Local neural speech recognition is provided by sherpa-onnx through the sherpa-rs bindings, using downloadable speech models.
