• Brain Dump → Structured Output: Ramble your scattered thoughts, then paste into an LLM to organize:

  hns  # "So I'm thinking about the refactor... we need to handle auth, but also consider caching..."
  # Paste to LLM: "Create a structured plan from these thoughts:"
  

• Communication: Compose Slack messages, emails, or chat responses hands-free.
• Note-Taking: Quickly capture thoughts and ideas without switching from the keyboard.
• Accessibility: Helpful for users who find typing difficult or painful.

Installation

Install via uv (recommended):

uv tool install hns

or pipx:

pipx install hns

or pip:

pip install --user hns

The first time you run hns, it will download the default Whisper model (base). This requires an internet connection and may take a few moments. Subsequent runs can be fully offline.

Usage

Basic Transcription

1. Run the command in your terminal:

   hns
   

2. The tool will display 🎤 Recording.... Speak into your microphone.
3. Press Enter when you have finished.
4. The transcribed text is automatically copied to your clipboard and printed to the console.

Configuration

Listing Models

To see all available transcription models:

hns --list-models

Setting the Model

Select a model by setting the HNS_WHISPER_MODEL environment variable. The default is base. For higher accuracy, use a larger model like medium or large-v3.

# Use the 'small' model for the current session
export HNS_WHISPER_MODEL="small"
hns

To make the change permanent, add export HNS_WHISPER_MODEL="<model_name>" to your shell profile (.zshrc, .bash_profile, etc.).

Setting the Language

By default, Whisper auto-detects the language. To force a specific language, set the HNS_LANG environment variable.

# Use an environment variable for Japanese
export HNS_LANG="ja"
hns
