LocalScribe v0.2.2-beta - Apple Intelligence Edition

Privacy-Focused Meeting Transcription for macOS

100% on-device processing • Zero network access • Encrypted storage

LocalScribe captures audio from meeting apps (Zoom, Google Meet, etc.), transcribes it locally using Whisper.cpp, and generates structured summaries using Apple Intelligence. Everything happens on your device—no data is sent to external servers.

Features

• System Audio + Microphone Capture - Records both sides of your meetings via ScreenCaptureKit
• Local Transcription - Whisper.cpp base.en model (bundled with app, no downloads needed)
• Apple Intelligence Summarization - 3-pass hierarchical summarization with structured markdown output
• Encrypted Storage - AES-256-GCM encryption for all transcripts, keys stored in macOS Keychain
• Zero Network Access - No external API calls, no telemetry, no analytics

Requirements

• macOS 15.1 (Sequoia) or later
• Apple Silicon (M1, M2, M3, M4, or newer)
• Apple Intelligence downloaded and enabled in System Settings
• ~500MB disk space

Installation

1. Download LocalScribe-v0.2.2-beta.zip below
2. Verify checksum (recommended):

   shasum -a 256 -c LocalScribe-v0.2.2-beta.zip.sha256
   # Should output: LocalScribe-v0.2.2-beta.zip: OK

3. Extract the .zip file
4. Move LocalScribe.app to /Applications
5. First launch: Right-click → Open (bypasses Gatekeeper for unsigned build)

• Encrypted: AES-256-GCM before writing to disk
• Keys: Stored securely in macOS Keychain
• Sandboxed: App runs in a security container for additional protection

sudo nettop -p $(pgrep -x "LocalScribe")

2. Delete app container:

   rm -rf ~/Library/Containers/transcribe-offline/

3. Delete Keychain entries: Open Keychain Access, search for "transcribe-offline", delete all entries
