Press Start, allow camera and microphone access when prompted, record your clip, then press Stop and download the file.
No. Recording uses your browser's built-in MediaRecorder API and the video is generated and downloaded locally — nothing is sent to a server at any point.
No software or extension is required. Your browser will ask for camera and microphone permission the first time you record, which you can revoke at any time.
Recordings are saved as WebM, which is natively supported by all modern browsers and can be converted to MP4 with the Video Format Converter if needed.
