Our review

Whisper is OpenAI's open-source speech-recognition model: accurate multilingual transcription that you can self-host, with a large ecosystem of wrappers built on top. It has become the open-source cornerstone for transcription and subtitles.

It needs your own compute, does transcription only, and ships without a graphical interface. But if you want free, offline-capable, high-quality transcription that you can wire into your own pipeline, Whisper is close to the default choice.
