ownscribe 0.3.0

Fully local meeting transcription and summarization CLI

ownscribe

Local-first meeting transcription and summarization CLI. Record, transcribe, and summarize meetings and system audio entirely on your machine – no cloud, no bots, no data leaving your device.

System audio capture requires macOS 14.2 or later. Other platforms can use the sounddevice backend with an external audio source.

Privacy

ownscribe does not:

• send audio to external servers
• upload transcripts
• require cloud APIs
• store data outside your machine

All audio, transcripts, and summaries remain local.

Features

• System audio capture — records all system audio natively via Core Audio Taps (macOS 14.2+), no virtual audio drivers needed
• Microphone capture — optionally record system + mic audio simultaneously with --mic
• WhisperX transcription — fast, accurate speech-to-text with word-level timestamps
• Speaker diarization — optional speaker identification via pyannote (requires HuggingFace token)
• Local LLM summarization — structured meeting notes via Ollama, LM Studio, or any OpenAI-compatible server
• One command — just run ownscribe, press Ctrl+C when done, get transcript + summary

Requirements

• macOS 14.2+ (for system audio capture)
• Python 3.12+
• uv
• Xcode Command Line Tools (xcode-select --install)
• One of:
  • Ollama — brew install ollama
  • LM Studio
  • Any OpenAI-compatible local server

Works with any app that outputs audio through Core Audio (Zoom, Teams, Meet, etc.).

Installation

Quick start with uvx

uvx ownscribe

On macOS, the Swift audio capture helper is downloaded automatically on first run.

From source

# Clone the repo
git clone https://github.com/paberr/ownscribe.git
cd ownscribe

# Build the Swift audio capture helper (optional — auto-downloads if skipped)
bash swift/build.sh

# Install with transcription support
uv sync --extra transcription

# Pull a model for summarization (if using Ollama)
ollama pull mistral

Usage

Record, transcribe, and summarize a meeting

ownscribe                    # records system audio, Ctrl+C to stop

This will:

1. Capture system audio until you press Ctrl+C
2. Transcribe with WhisperX
3. Summarize with your local LLM
4. Save everything to ~/ownscribe/YYYY-MM-DD_HHMMSS/

Options

ownscribe --mic                               # capture system audio + default mic (press 'm' to mute/unmute)
ownscribe --mic-device "MacBook Pro Microphone" # capture system audio + specific mic
ownscribe --device "MacBook Pro Microphone"   # use mic instead of system audio
ownscribe --no-summarize                      # skip LLM summarization
ownscribe --diarize                           # enable speaker identification
ownscribe --model large-v3                    # use a larger Whisper model
ownscribe --format json                       # output as JSON instead of markdown
ownscribe --no-keep-recording                 # auto-delete WAV files after transcription

Subcommands

ownscribe devices                  # list audio devices (uses native CoreAudio when available)
ownscribe apps                     # list running apps with PIDs for use with --pid
ownscribe transcribe recording.wav # transcribe an existing audio file
ownscribe summarize transcript.md  # summarize an existing transcript
ownscribe config                   # open config file in $EDITOR
ownscribe cleanup                  # remove ownscribe data from disk

Configuration

Config is stored at ~/.config/ownscribe/config.toml. Run ownscribe config to create and edit it.

[audio]
backend = "coreaudio"     # "coreaudio" or "sounddevice"
device = ""               # empty = system audio
mic = false               # also capture microphone input
mic_device = ""           # specific mic device name (empty = default)

[transcription]
model = "base"            # tiny, base, small, medium, large-v3
language = ""             # empty = auto-detect

[diarization]
enabled = false
hf_token = ""             # HuggingFace token for pyannote

[summarization]
enabled = true
backend = "ollama"        # "ollama" or "openai"
model = "mistral"
host = "http://localhost:11434"

[output]
dir = "~/ownscribe"
format = "markdown"       # "markdown" or "json"
keep_recording = true     # false = auto-delete WAV after transcription

Precedence: CLI flags > environment variables (HF_TOKEN, OLLAMA_HOST) > config file > defaults.

Speaker Diarization

Speaker identification requires a HuggingFace token with access to the pyannote models:

1. Accept the terms for both models on HuggingFace:
   • pyannote/speaker-diarization-3.1
   • pyannote/segmentation-3.0
2. Create a token at https://huggingface.co/settings/tokens
3. Set HF_TOKEN env var or add hf_token to config
4. Run with --diarize

Acknowledgments

ownscribe builds on some excellent open-source projects:

• WhisperX — fast speech recognition with word-level timestamps and speaker diarization
• faster-whisper — CTranslate2-based Whisper inference
• pyannote.audio — speaker diarization
• Ollama — local LLM serving
• Click — CLI framework
