I originally added this to my site to speed up my video editing process. Last year I started a youtube channel and for some of my longer videos it's annoying to rely on youtube or capcut to transcribe when Whisper is open source. Capcut also recently updated their T&Cs to say they own your content if you use their app, so I cancelled my subscription.

Another use-case I have is recording my claude prompts as audio, transcribing them, and then pasting them into my terminal. I mostly work on the CLI (claude, ffmpeg, whisper), but I wanted to make a browser version.

Not reinventing the wheel here, just using Huggingface/Xenova Transformers.js to run Whisper in the browser with a background worker.

If you're interested in building this yourself, there's a bunch of examples on Huggingface https://huggingface.co/collections/Xenova/transformersjs-dem...
