Why it is safe
The noise filter (DeepFilterNet, open source, about 22 MB) is downloaded once, when you add a file, and runs on your device. The file is not sent over the internet: once the filter has loaded it keeps working offline.
We never ask for an account and keep nothing: close the tab and the recording is gone.
Questions
What noise does it remove?
Steady and background noise around a voice: fans, air conditioning, hum, hiss, traffic, keyboard, a café. It is trained on speech.
Does it work with music?
No. The filter keeps voices and treats everything else as noise, so it damages music and singing with instruments.
How much does it cost?
Nothing. No sign-up, no length limit and no watermark.
Do I need to install anything?
No. It works in a current browser on a computer, tablet or phone.
