Screen sharing with a small studio for overlays and blur

Two steps to go live

You choose what to share, whether a single window, a browser tab or the entire screen, and check the preview. Then you press Go live. Sound from the shared window can be included with one tick box, and you can switch what you share while you are live.

Watching a share

The viewer gets a clean stage with simple controls.

• A stream health indicator showing quality and frame rate.
• Fullscreen, pop-out and quality controls.
• Reactions that float up the side without covering the picture.
• A strip showing who is sharing and how many are watching.

The studio

The studio is where you set the scene. Layers let you place your screen, a webcam, text and blur boxes on a canvas, and scenes save a layout so you can switch between them, for example Starting soon, Main and Be right back.

Overlays with placeholders

Text overlays can contain placeholders. Write {viewers} watching and the number fills itself in as people join. The placeholder approach keeps overlays honest and saves manual editing during a live session.

Why a studio and not only a share button

Most screen sharing is a raw feed of whatever happens to be on your display. That works for a quick question and falls apart the moment you want to present something properly, or the moment a private notification appears. The studio is a small layer between your screen and the viewers, where you decide what they see.

In practice that means choosing what is shared, laying out a scene, adding a name or a title as an overlay, and covering anything that should not be visible. It is meant to be quick to set up and easy to ignore when you do not need it.

What it will not do

A blur box is a visual cover on what viewers see. It is not a security boundary, and it cannot protect something that you reveal in another window or say out loud. The blog post on blur boxes goes through the limits in more detail, and the safest habit is still to share a single window rather than a whole screen when you can.

The studio is a plan and has not been built to release quality. We would rather say that than overstate it, and we will describe what it does and does not do when there is a version to try.

Performance and where it runs

A studio that processes video has a cost in power and bandwidth, and we do not yet know how heavy it will be on an ordinary laptop. It is meant to work on the desktop apps first. We are not quoting frame rates or resolution limits, because nothing has been measured against real hardware, and we will publish numbers only when we have them.

Blur boxes for privacy

A blur box covers an area of your shared screen, such as an inbox or a notification corner, and stays in place while you work. It is applied before the picture leaves your computer, so viewers receive the blurred version, not a recording with a mask on top.

Blur is a convenience, not a guarantee. The best protection is not having sensitive material open while you share, and the app will say so in its help text.
