Transcribe MP3 is an independent, free tool for turning audio files into text without uploading them. It is built on open-source software: the Whisper speech recognition model released by OpenAI, the ONNX conversions published on the Hugging Face hub, and the Transformers.js library. The site is not affiliated with those projects.
Funding
The tool is free. The first transcript download is free. A later download asks for a name and email so the transcript can be emailed. There is still no fee. The site may later show clearly labeled ads or links to paid human transcription services for people who need verified transcripts. None are live today.
