EchoFluid is a privacy-first video and audio transcription tool I built to solve a problem I personally ran into: most transcription services require uploading the entire video file, which is slow, bandwidth-heavy, and sometimes not acceptable for sensitive content.

What’s different:

- Videos are processed locally in the browser to extract audio before upload

- Only the audio is sent for transcription, not the full video

This results in:

- Faster uploads

- Much lower bandwidth usage

- Support for much larger video files

- Better privacy by default
