ownscribe 0.6.0

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)
• Pipeline progress — live checklist showing transcription, diarization sub-steps, and summarization progress
• Local LLM summarization — structured meeting notes via Ollama, LM Studio, or any OpenAI-compatible server
• Summarization templates — built-in presets for meetings, lectures, and quick briefs; define your own in config
• 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
• ffmpeg — brew install ffmpeg
• 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.).

Tip: Your terminal app (Terminal, iTerm2, VS Code, etc.) needs Screen Recording permission to capture system audio. Open the settings panel directly with:

open "x-apple.systempreferences:com.apple.preference.security?Privacy_ScreenCapture"

Enable your terminal app, then restart it.

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 --language en                        # set transcription language (default: auto-detect)
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
ownscribe --template lecture                  # use the lecture summarization template

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
telemetry = false         # allow HuggingFace Hub + pyannote metrics telemetry
device = "auto"           # "auto" (mps if available), "mps", or "cpu"

[summarization]
enabled = true
backend = "ollama"        # "ollama" or "openai"
model = "mistral"
host = "http://localhost:11434"
# template = "meeting"    # "meeting", "lecture", "brief", or a custom name

# Custom templates (optional):
# [templates.my-standup]
# system_prompt = "You summarize daily standups."
# prompt = "List each person's update:\n{transcript}"

[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.

Summarization Templates

Built-in templates control how transcripts are summarized:

Template	Best for	Output style
meeting	Meetings, standups, 1:1s	Summary, Key Points, Action Items, Decisions
lecture	Lectures, seminars, talks	Summary, Key Concepts, Key Takeaways
brief	Quick overviews	3-5 bullet points

Use --template on the CLI or set template in [summarization] config. Default is meeting.

Define custom templates in config:

[templates.my-standup]
system_prompt = "You summarize daily standups."
prompt = "List each person's update:\n{transcript}"

Then use with --template my-standup or template = "my-standup" in config.

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

On Apple Silicon Macs, diarization automatically uses the Metal Performance Shaders (MPS) GPU backend for ~10x faster processing. Set device = "cpu" in the [diarization] config section to disable this.

Acknowledgments

• faster-whisper — CTranslate2-based Whisper inference
• pyannote.audio — speaker diarization
• Ollama — local LLM serving
• Click — CLI framework
