whisper.trevorhealy.me

whisper.trevorhealy.me is a straightforward web tool that lets you upload large audio files, split them in your browser, and send them to OpenAI's Whisper model for transcription. It supports common formats like mp3, wav, m4a, and webm. You need your own OpenAI API key to use it — there's no built-in billing or free tier. A demo option is available if you just want to see how it works without uploading a file.

The tool solves a specific problem: Whisper has a file size limit, so transcribing long recordings usually requires manual splitting or command-line work. This page handles that partitioning automatically in the browser before sending each chunk to the API. The interface is minimal — drag and drop a file, paste your API key, and click save. There are no extra features, settings, or accounts to manage.

This is best for anyone who needs to transcribe lengthy audio but doesn't want to deal with code or desktop software. Journalists transcribing interviews, researchers working with lecture recordings, and podcasters converting episodes to text will find it useful. It's a simple, focused tool that does one thing and does it without fuss.
