What This Generator Creates
This tool creates a Google Apps Script for a presentation you control. The script inserts a visible text-box marker on every slide, every slide except the first, or a numbered slide range.
It does not create a native Google Slides comment. The marker is deliberately part of the slide so it remains obvious when a team exports, presents, or revisits a working deck.
Why the Generated Version Is Safer to Rerun
The original short script adds a new text box every time it runs. That is useful for a one-time pass, but repeated runs can stack duplicate markers.
The generated version gives each marker an alt-text title and checks for that title before adding another one. You can choose to replace existing generated markers or skip slides that already have one. A separate cleanup function removes only the markers created by this tool.
How to Run It
- Open the Google Slides presentation you control.
- Choose Extensions → Apps Script.
- Replace the starter code with the generated script.
- Save the project and run
addUpdateMarkers. - Review the requested Google authorization before approving it.
Run removeUpdateMarkers when the deck is complete and you want to remove the generated markers.
Practical Boundary
The generator runs entirely in the browser and does not receive your label, colors, slide range, deck contents, or generated script. Google will still ask you to authorize the copied script when it first modifies the active presentation.
Test it on a copy when the deck is important. The script can remove and replace markers that carry its reserved alt-text title, so do not reuse that title for unrelated slide elements.
