Speech-to-text CLI. 100% local. Built for developers.

---

hns is a speech-to-text CLI tool to transcribe your voice from your microphone directly to clipboard. Integrate hns with Claude Code, Ollama, LLM, and more CLI tools for powerful workflows.

hns transcribes your voice 100% locally using faster-whisper. The whisper model is downloaded automatically on first run and after that, hns can be used completely offline. After transcription, the text is displayed in the terminal (written to stdout) as well as automatically copied to your clipboard, ready to be pasted anywhere with Ctrl+V or Cmd+V.

With hns, you can:

• Drive AI coding agents like Claude Code, Codex CLI, and Cursor CLI with your voice
• Dictate and get polished text for emails, Slack messages, and documents
• Speak freely in a stream-of-consciousness style and get polished, coherent journal entry or note

...and much more! Just integrate hns with your favorite CLI tools.
