hns

hns is a speech-to-text command-line tool that transcribes microphone input directly to the system clipboard. It operates entirely offline on consumer-grade hardware without subscriptions or data transmission to external services.

The tool addresses the need for local voice input in terminal-based workflows. It records speech from a microphone and converts it to text placed on the clipboard, enabling seamless pasting into other applications. Integration examples include piping output to tools such as Claude Code, Ollama, and other command-line interfaces for LLM-driven tasks. Specific use cases named are voice programming, where detailed prompts are provided to coding agents like Claude Code, Codex CLI, or Cursor CLI, and voice journaling to capture thoughts quickly.

As a terminal-native utility, hns follows the Unix philosophy of performing one task well. It runs via a simple installation command using uv tool install hns and is positioned for developers who combine it with existing CLI tools and scripts. Data remains on the local machine, avoiding cloud processing, model training, or third-party sharing.

The project maintains documentation and a GitHub repository for further details. It is presented as suitable for scenarios requiring fast, private speech capture without recurring costs.
