Frequently Asked Questions

How do I record my screen with sound?

Keep "Record my voice" ticked for your microphone. For the sound of a video or a call, tick "Share audio" in the window your browser opens when you start; in Chrome and Edge, sharing a tab gives the most reliable sound.

Is there a time limit or a watermark?

No. You can record as long as your computer has free memory, and the video has no watermark.

Does it work on phones?

No. Phones and tablets do not let websites record the screen. Android and iPhone both have a screen recorder in their quick settings.

Where is the recording saved?

In your browser until you click Download, then in your Downloads folder. Nothing is sent to us.
