About Whisper Web AI | Browser Speech to Text

Whisper Web AI is an independent browser-based transcription site built around the open-source whisper-web project. The goal is straightforward: make Whisper easier to use for real transcription work without requiring a desktop setup or API workflow.

The product is organized around three jobs:

  • Audio to Text for saved files
  • Voice to Text for live microphone capture
  • URL to Text for direct public audio links

What Whisper Web AI Does

Whisper Web AI supports:

  • Local file upload
  • Microphone recording
  • Audio input from a URL
  • Transcript chunks with timestamps
  • Transcript export in formats such as TXT and JSON
  • Model, language, and task controls
  • Multilingual transcription options

These workflows are useful for meetings, interviews, podcasts, subtitles, lectures, voice notes, and searchable archives.

Privacy by Workflow

  • Local file uploads are read and transcribed in your browser.
  • Microphone recordings are captured and transcribed in your browser tab.
  • URL imports may use a streaming proxy when the remote server blocks direct browser access. The transcription step still runs locally after the audio reaches the browser.

If you are evaluating the privacy model, treat those workflows differently instead of assuming every feature works the same way.

How to Verify Local Processing

If you want to confirm the behavior yourself:

  1. Open browser developer tools and switch to the Network panel.
  2. Run a local file or microphone transcription.
  3. Confirm that your audio file is not uploaded to a third-party transcription API during the transcription run.
  4. If you test the URL workflow, expect to see a fetch request when the source requires proxying for CORS reasons.

Limitations

  • First-time model download can be large and slow on weaker connections.
  • Long recordings depend on available RAM and browser stability.
  • Browser decoding support varies by format and device.
  • Transcript quality changes with noise, overlap, accents, and model size.
  • Review output manually before using it for legal, medical, or other high-stakes work.
