Read your script over the app you are demoing.

Two things want the same screen

A talking-head video has one thing on screen: you. A demo has two. The app you are showing, and the words you meant to say about it. Both need your eyes, and in most setups they live in different windows.

The usual workarounds all cost something. A notes window beside the app shrinks the app and pulls your eyes sideways. Notes on a second monitor turn every line into a head turn. Notes on paper mean looking down. And winging it means the demo takes three times longer than it should, because every step gets explained twice.

What you actually want is the script on top of the app, out of the way of your clicks, and nowhere in the recording.

What the overlay does

Mirrento has an overlay mode for exactly this. Instead of opening the prompter in its own window, it floats your script over whatever is on the screen.

• It stays on top. The overlay sits above your other windows, so clicking into the app you are demoing does not bury it.
• Clicks go through it. The overlay does not take the mouse. Click on a button that sits under the text and the click lands on the button, not on the script.
• It follows you like the prompter does. Voice follow, chapters and slide cues work the same way in the overlay as in the prompter window. The text moves when you speak and waits when you stop to click.

Open it with the Overlay button next to Prompter in the app's control bar, or from the Mirrento menu bar icon. There is a second way in: in the same control bar, choose Screen behind the text (it is also in Settings, Display, under Behind the text). The prompter then turns see-through where it already is, same size, same place and same formatting as your prompter, with your screen showing behind the text and clicks going through to it. The overlay and the prompter window are one or the other: opening the overlay closes the prompter window, and the other way round.

Put it where the app is not

Every app has a quiet part of the screen. A toolbar you will not touch, an empty corner, a strip at the bottom. The overlay goes there. In Settings, Display, under Overlay layout, you have four presets:

• Notch. A small dock just under the menu bar, in the middle. On a MacBook it sits at the notch, right under the camera. Good for short lines, and the closest the text can get to the lens.
• Top. A strip across the top of the screen, below the menu bar. Good for apps whose work happens in the lower half.
• Bottom. A strip across the bottom, above the Dock. Good for apps with menus and tabs at the top.
• Corner. A block in the top right corner. Good for apps that keep their content on the left or in the centre.

If none of them fits, choose Edit layout. The overlay stops letting clicks through, and you drag it to move it and drag an edge or a corner to resize it. Let go of a drag near one of the four presets and it snaps into that preset; hold Shift as you let go to place it exactly where you dropped it. Press Escape or choose Edit layout again when you are done. Mirrento keeps that custom size and place for the screen it is on, and the next time you open the overlay it comes back on the screen where you last used it.

Make it quiet enough to work under

An overlay that hides the app is just a different problem. Three settings keep it light:

• Overlay background. From a solid dark panel down to fully clear, with only the text left. Clear works over a plain background. Over a busy screen, keep some of the panel so the words stay readable.
• Overlay text. How strong the text itself is. Turn it down and the words fade back while you look at the app, and stay readable when you look for them.
• Overlay text size. For the Top, Bottom, Corner and custom layouts. Smaller text means more of the app stays visible; larger text means a shorter glance.

If you want to scroll the overlay with the mouse or trackpad, hold Option while the pointer is over it. Let go and clicks pass through again.

An AI assistant can set this up for you, too. Mirrento's built-in connection for assistants lets one pick the overlay layout, the background, the text strength and size, and the camera behind the text. It can hide the script from a screen share but never show it: that switch stays yours. Letting an AI assistant run your teleprompter covers the setup, and if you would rather that assistant be a clone of you, that is Klyr, an AI clone of you, a separate product from Mirrento.

Two shortcuts that work from any app

During a demo, the app you are showing is in front, not Mirrento. So the overlay has two shortcuts that work whichever app is active:

• ⌃⌥⌘O hides the overlay, or shows it again. Useful for the one screen you want completely clean.
• ⌃⌥⌘L turns Edit layout on or off, so you can move the overlay out of the way without leaving the app.

They do not need any extra permission in System Settings.

What about the recording?

The script is for you, not for the viewer. By default, Mirrento keeps the overlay and the prompter window out of screen recordings, screenshots and screen shares, while the main Mirrento window stays capturable as normal. I checked it in a real Google Meet screen share, and the script did not show.

Sometimes you want the opposite, for example when the demo is about Mirrento itself. Turn on Visible in screen share: the eye button in the control bar, the same switch in Settings, Display, or the item in the menu bar icon. While it is on, the eye button and the menu bar icon turn red, and it switches itself off the next time Mirrento starts, so the script is never left visible by accident.

With a recorder or meeting app other than Meet, make a ten-second test recording before the real demo and watch it back. It costs less than finding out in the edit. The same habit from reading notes on a video call applies here.

Write the script for a demo

A demo script is not a talking-head script. Your hands are busy and the screen is telling half the story, so the words can do less.

• One chapter per step. Open the settings, change the value, show the result. Each step its own chapter, so a fumbled click means redoing one step, not the whole demo. The same habit is in how to format a script for a teleprompter.
• Say why, let the screen show what. "This is the part that saves you an hour" beats reading out every label the viewer can already see.
• Leave room for the click. Voice follow waits when you stop talking, so a pause to click is free. Do not write words to fill it.
• Keep slide cues for slides. If part of the demo is a deck, the cues from presenting slides on camera alone work in the overlay too.

If your demos keep stalling on the switch between the app and your notes, the 7-day trial is enough to record one walkthrough with the script floating over the app and see how many pauses are left.
