## The Privacy Problem with Cloud Transcription Every time you use a traditional voice transcription service, your audio is uploaded to remote servers for processing. This creates several concerns: - **Data exposure**: Your conversations travel across the internet to third-party servers - **Storage uncertainty**: You don't know how long your audio is retained - **Compliance risks**: Healthcare, legal, and financial professionals face strict data handling requirements - **Network dependency**: No internet means no transcription At SyntriMeet, we believe you shouldn't have to choose between convenience and privacy. That's why we built **true offline transcription** from the ground up. ## How SyntriMeet's Offline Mode Works Our offline transcription is powered by **whisper.cpp**, a highly optimized implementation of OpenAI's Whisper model that runs entirely on your device: ### 1. Local Model Execution When you enable offline mode, SyntriMeet downloads a Whisper model to your computer. The model runs locally using: - **Apple Silicon acceleration** (CoreML/Metal) on Mac - **DirectML** acceleration on Windows - **CPU fallback** for maximum compatibility The result? Transcription speeds of 5-10x realtime on modern hardware, with zero data leaving your device. ### 2. Automatic Mode Switching SyntriMeet intelligently switches between cloud and local processing: - **Online**: Uses our cloud API for fastest results - **Offline detected**: Seamlessly falls back to local processing - **Force offline**: Enable in Settings to always use local transcription You'll see a clear indicator showing whether you're in Cloud or Local mode at all times. ### 3. Model Management We've made model management simple: - Choose from multiple model sizes (Tiny to Large) - See memory requirements before downloading - Download progress with pause/resume support - Automatic updates when improved models are available ## Why This Matters for Professionals ### Healthcare (HIPAA Compliance) Medical professionals handle protected health information (PHI) daily. With offline mode: - Patient conversations are transcribed without cloud transmission - No third-party data processing agreements needed - Full control over where transcripts are stored ### Legal (Attorney-Client Privilege) Lawyers must protect privileged communications: - Deposition notes stay on your device - Client meeting transcripts remain confidential - Full audit trail of local processing ### Finance (Regulatory Compliance) Financial professionals face strict regulations: - Client discussions transcribed privately - Meeting records kept locally - No cross-border data concerns ## Technical Deep Dive For the technically curious, here's what makes our offline mode special: ``` Audio Input → Preprocessing (16kHz resample) → Whisper Model → Text Output ↓ All processing on-device No network requests No data transmission ``` ### Performance Benchmarks | Model | Size | Memory | Speed (Apple Silicon) | |-------|------|--------|----------------------| | Tiny | 75 MB | 1 GB | 15x realtime | | Base | 142 MB | 2 GB | 10x realtime | | Small | 466 MB | 3 GB | 6x realtime | | Medium | 1.5 GB | 5 GB | 3x realtime | | Large | 2.9 GB | 10 GB | 1.5x realtime | For most users, the Small model offers the best balance of accuracy and speed. ## Getting Started with Offline Mode 1. Open SyntriMeet Settings 2. Navigate to "Local Models" 3. Download your preferred model size 4. Enable "Force Offline Mode" or let auto-detection handle it Your transcriptions will now process entirely on your device. ## The Future of Private Voice AI We believe the future of voice AI is local-first. As models become smaller and hardware becomes faster, more processing will happen on-device by default. SyntriMeet is leading this transition, giving you the power of AI without sacrificing your privacy. --- *Ready to try privacy-first transcription?
