Frequently asked questions
Are my videos uploaded?
No. Everything is made in your browser, on your own device. Nothing is sent to a server.
Why use headphones?
Without them, your microphone hears the video from your speakers. Echo cancellation reduces it, but headphones keep your reaction clean.
Which devices can record?
Any browser that can use your camera: Chrome, Edge, Firefox and Safari on computers and phones.
Can I edit it more?
Yes. Press "Edit in the video editor" to open the same video in our full editor: add text, music, captions and more.
Is it free?
Yes. Free, with no signup and no watermark.
