Audio to Text (Transcription) is a free, browser-based tool that uses OpenAI's Whisper speech recognition model to convert spoken audio into written text, with optional timestamps.
Heads up: this uses a real AI speech recognition model (Whisper, Apache-2.0 licensed) running entirely in your browser via WebAssembly — nothing is uploaded to a server. The first use downloads and caches the model (~40MB); your browser only downloads it once.
How to use the Audio to Text (Transcription)
- Upload an audio file.
- Optionally enable timestamps.
- Click Transcribe \u2014 the first use downloads the AI model (~40MB, cached afterward).
- Copy the transcript once processing finishes.
