For security and compliance work, I sometimes need to transcribe private audio files. Uploading those files to a third-party API is a non-starter.

I wanted something that runs locally, on my own device, with zero uploads.

So I built Online Transcript Generator (thanks to Whisper Web).

It runs directly in your browser. No signups. No backend processing. No file uploads.

What it does

• Fast on supported devices: WebGPU-accelerated transcription (falls back to WASM if WebGPU is not available)
• Exports: SRT, TXT, or JSON
• Privacy-first: your audio stays on your device. Everything runs locally in the browser.
• Bonus tool: a free audio splitter to cut large files into smaller parts before transcribing (or for general editing)
