Does the screen recorder work without installing anything?

Yes. Chrome 72+ and Edge 79+ support getDisplayMedia(), which lets you capture your screen without any extension, plugin, or downloaded app. Just open the tool and click 'Start Recording'.

Can I record just one browser tab instead of the whole screen?

Yes. When you click 'Start Recording', your browser shows a native screen picker where you can choose to share a specific tab, a window, or your entire monitor.

Does the screen recorder capture system audio?

Chrome on Windows supports capturing system audio via the screen picker. macOS does not allow system audio capture from browsers due to OS restrictions. Microphone audio can be added separately.

Why doesn't screen recording work in Safari?

Safari does not support the getDisplayMedia() API as of 2026. Use Chrome or Edge for screen recording. Firefox has partial support starting from version 66.
