Your Data, Your Control: Building a Self-Hosted Transcription API

As organizations and individuals grow concerned about cloud services' privacy implications and recurring costs, local AI processing has become increasingly attractive. This project demonstrates how to build a self-hosted transcription API that maintains accuracy while cutting file sizes by 98% through smart preprocessing with ffmpeg and the lightning-fast faster-whisper. The result unlocks transcription capabilities for personal projects, sensitive meetings, and resource-constrained environments—categories where commercial services have typically been the only option.
