Frequently Asked Questions

Is it free?
Yes, no account needed.

Does my recording get uploaded anywhere?
No, recording is handled entirely by your browser's own APIs and stays on your device — it never goes to a server.

What format do I get?
WEBM, a video format natively supported by browsers.

Can I record my microphone too?
Not currently — only the screen and optional system/tab audio are recorded, microphone isn't supported.

Is there a limit on recording length?
No, you can record as long as you like; very long recordings may slow down since your browser's memory is finite.
