Frequently asked
What is a screen recorder?
A screen recorder is a tool that captures what happens on your screen as a video file, usually with optional audio and webcam, so you can show something instead of describing it.
People use screen recorders for software tutorials, product demos, walkthroughs, feedback, bug reports, and quick async updates for colleagues. Most let you record the whole desktop, a single window or tab, and add narration from your microphone.
Sirvez is one free option: it's a Chrome extension that records your screen, a browser tab, your full desktop, and your webcam, then saves the video locally in your browser so nothing leaves your machine unless you choose to upload it.
