What Is AI Audio Transcription?
AI audio transcription converts spoken audio into written text using the Whisper speech recognition model running directly in your browser. Unlike cloud-based transcription services that upload your audio to remote servers, our tool processes everything locally on your device using WebGPU or WebAssembly. This makes it ideal for transcribing confidential meetings, legal proceedings, medical dictation, interviews, and podcast episodes where privacy is critical. The model supports accurate timestamp generation for subtitle creation.
