How to Use Google Meet Companion Mode in a Conference Room ​

Summary ​

When you are sitting in a conference room that is already connected to a Google Meet, joining the same meeting from your personal laptop usually causes a piercing, high-pitched audio echo. "Companion Mode" solves this. It lets you join the meeting to share your screen or view the chat, while completely disabling your laptop's microphone and speakers to prevent feedback.

Prerequisites ​

  • The conference room hardware (the room system) must already be joined to the Google Meet.

Instructions ​

1. Join Using the Companion Mode Button (Easiest) ​

  1. Open the Google Meet link from your calendar invite on your laptop.
  2. You will arrive at the "Ready to join?" preview screen.
  3. Do not click the main "Join Now" button.
  4. Instead, look below the main button for the option that says Use Companion mode.
  5. Click it. Your laptop will enter the meeting with its microphone and speakers permanently muted. The room hardware handles the audio, while your laptop can be used for screen sharing or chat.

2. Join Using the Direct URL ​

If you don't have the calendar invite handy or want a shortcut:

  1. Open your web browser.
  2. Type g.co/companion into the address bar and press Enter.
  3. Type in the meeting code (the letters at the end of the Google Meet link, e.g., abc-defg-hij).
  4. You will instantly bypass the preview screen and join the meeting in Companion Mode.

3. Sharing Your Screen in Companion Mode ​

The most common use for Companion Mode is presenting a slideshow without needing an HDMI cable.

  1. Once you are in the meeting in Companion Mode, look at the bottom toolbar.
  2. Click the Present now icon (a rectangle with an up arrow).
  3. Choose whether to share a Chrome Tab, a Window, or your Entire Screen.
  4. The conference room screen (and all remote participants) will now see your laptop screen.

Troubleshooting ​

WARNING

Never unmute your microphone while in Companion Mode. Doing so will instantly create a feedback loop with the conference room's microphone, deafening everyone on the call. If you need to speak, talk normally—the room microphone will pick up your voice.
