What Is AI Audio Transcription?
AI Audio Transcription is a free online tool that transcribe audio and speech to text with AI — runs entirely in your browser, no uploads. No files are uploaded — everything is processed locally on your device.
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.
Privacy guarantee: AI Audio Transcription processes all files directly in your browser using WebAssembly. No data is uploaded to any server, no information is collected, and the tool works offline after loading. Unlimited usage with no signup, no watermarks, and no file size limits.
