Sourdine: Open-Source macOS App for 100% Local AI Transcription

Sourdine represents a practical breakthrough for users seeking privacy-preserving AI applications on macOS. By running transcription models entirely locally, the application avoids the latency and privacy concerns associated with cloud-based transcription services. This approach is particularly valuable for professionals handling sensitive conversations who need real-time or near-real-time transcription without uploading audio data to third-party servers.

The project demonstrates the growing maturity of on-device inference for complex tasks like speech recognition. As local LLM deployment becomes more sophisticated, applications like Sourdine show how transcription and understanding can be combined into cohesive, privacy-first tools. The open-source nature of the project means the community can contribute optimizations for different Mac hardware configurations, including Apple Silicon.
