Having Trouble Recording with DemoAir

If you have trouble like below when recording and sharing with DemoAir, there are a few things we suggest trying that you can click to find out.

Drawing tools are unavailable

You may not see DemoAir drawing tools on your current tab, even if you have enabled Drawing Tools.

This occurs because our drawing tools are embedded into the website you are currently visiting, essentially by being added to the existing URL. In order to use the drawing tools, you'll need to record on a "live" website.

There are several examples of webpages they are not live websites:

  • Blank new browser Tab
  • Any URLs that begin with chrome-extension (as all the pages in the DemoAir extension)
  • The Google Chrome Store

1. Use Drawing Tools in your PowerPoint Presentation

Even though DemoAir is not available in PowerPoint, if you want to annotate over your PowerPoint, highlight, draw, or otherwise add live written content to PowerPoint while presenting, you can use PowerPoint “Pen” or “Highlighter”

  • Start PowerPoint slide show
  • Click ”Record Slide Show”
  • Choose "Record from Current Slide” or “Record from Beginning”

record slide

Choose either "Pen" or "Highlighter".


When you are finished, you will be prompted to save or eraser your annotations.

Annotations may will be saved to the presentation then.

2. Use Drawing Tools in Google Slide

DemoAir allows you to embed your webcam and use our drawing tools in Google Slide Presentation.

3. Use Drawing Tools to record browser

If you start a desktop or tab recording on any live webpage, you will see the drawing tools bar appear on the bottom left corner of your browser tab. Please ensure the drawing tools are enabled from the setting options.

I can't find the DemoAir chrome extension

Please note that you can't add extensions when your browse is in Incognito mode or as a guest. If you have already installed DemoAir but can’t find it in the browser extension, it is likely that it is hidden from your extension or disabled.

I want to record my application and full screen but it wasn't captured

When you start a desktop recording, you will be provided two options: one is Entire Screen and the other is Window:


If you choose to record a specific application window, DemoAir will only capture that application. (For example: Microsoft Word)

However, if you enter another application or webpage on your entire screen, DemoAir will not capture the interface, The recording will stay still for the application you selected to capture.

If you enter entire screen with that application, DemoAir will still only record the application.

So if you want to record the full screen not only an application, please choose the Entire Screen mode, not an Application Window. Then everything on your screen will be recorded.

There is an echo when recording my Microphone and tab/system audio

This happens when tab/system audio is played loudly through your computer speaker. The audio output from the speakers may feed into the microphone and produce echoes.

To avoid the echo, please do the following one or both:

1. Wire a headset when recording both microphone and tab/system audio.

2. Muting the tab/system audio on your computer speakers (DemoAir will still record the tab/system audio in the output recording).

When sharing to Google Classroom, I get "Couldn’t attach file, Attach a file that you own"

If you try to share a DemoAir recording or Google Drive link you are not the owner of, you may see a pop-up that says "Couldn’t attach file, Attach a file that you own"

google classroom

This happens when your colleagues share a video in their Google Drive with you. This video is still be owned by your colleagues.

Google Classroom will only allow you to upload videos that you are the owner of the Google Drive video.

There is one way that you can use:

You can then download the video to your computer and upload your copy directly to your Google Classroom assignment.

My webcam is not detected

If DemoAir is unable to detect your webcam, the extension will not be able to do your webcam recording or embed your webcam in the recording.
