This tool is a pure browser-based online screen recording system. No software installation is required; it runs directly in the web page and allows you to record your screen and download the video. It is built entirely on native browser capabilities and can be used for teaching recordings, operation demonstrations, meeting notes, software demos, and more. This feature requires a modern browser such as Chrome, Edge, Firefox, or Safari. Click the "Start Recording" button, and the browser will prompt you to select permissions. Follow the instructions to proceed. You can pause or resume recording at any time. Click the "Stop Recording" button to end the session. After recording, the system will automatically generate a video file (.webm format), and you can click "Download Video" to save it locally. All data is processed locally in the browser and is not uploaded to any server, ensuring privacy protection.
