The Mavio browser extension captures audio directly from your browser tab. It is a lightweight alternative to the meeting bot that works without adding a participant to your call.

​
How it works

When you click the Mavio extension icon during a browser-based meeting, the extension uses the Chrome Tab Capture API to record audio from that specific tab. Only audio from the active meeting tab is captured — other tabs, system sounds, and notifications are excluded. The captured audio is streamed to Mavio’s processing servers in real time. When you stop the recording, the full transcript, summary, and action items are generated within minutes.
Unlike the meeting bot, the browser extension does not add a visible participant to your call. Other attendees will not see a “Mavio Notetaker” in the participant list.

​
Getting started

1

Install the extension

Visit the Chrome Web Store and search for Mavio Meeting Notes, then click Add to Chrome.
2

Pin the extension

Click the puzzle piece icon in Chrome’s toolbar and pin Mavio so the icon is always accessible.
3

Sign in

Click the Mavio icon and log in with your Mavio account credentials.
4

Start recording

Join a meeting in your browser (Zoom web client, Google Meet, Microsoft Teams web). Click the Mavio icon and select Start Recording. A small indicator appears on the tab showing the recording is active.
5

Stop recording

Click the Mavio icon again and select Stop Recording, or close the meeting tab. Mavio will process the audio and your notes will appear in the dashboard.

​
Supported meeting platforms

The extension detects and optimizes for these platforms automatically:
  • Google Meet — full support, auto-detects meeting pages
  • Zoom (web client) — works when using Zoom in the browser instead of the desktop app
  • Microsoft Teams (web) — full support via teams.microsoft.com
  • Webex — supported via the browser-based client
  • Any audio/video page — the extension can capture audio from any tab, including YouTube, Loom, or custom webinar platforms

​
Including your microphone

By default, the extension captures only the tab audio (what the other participants are saying). To include your own voice:
  1. Click the Mavio extension icon.
  2. Toggle Include microphone to on.
  3. Grant microphone permission if prompted.
This mixes your microphone audio with the tab audio, ensuring the transcript includes everything you said.
When microphone capture is enabled, the extension requests microphone permission from Chrome. You can revoke this permission at any time from Chrome’s site settings.

​
Auto-recording

You can configure the extension to start recording automatically when it detects a meeting page:
  1. Click the Mavio extension icon and open Settings.
  2. Toggle Auto-record meetings to on.
  3. Choose which platforms to auto-record (Google Meet, Zoom, Teams, or all).
When you navigate to a matching meeting URL, the extension begins recording without manual intervention.
Auto-recording starts immediately when a meeting page loads. Make sure you are comfortable recording all detected meetings, or use the platform-specific filters to limit which meetings are recorded.

​
Troubleshooting

The extension only activates on web pages — it will not work on Chrome internal pages (chrome://, chrome-extension://). Navigate to a regular webpage or meeting URL.
Ensure the meeting tab is producing audio. If the tab is muted in Chrome (right-click tab > Unmute), the Tab Capture API will not receive audio. Also check that no other extension is blocking Mavio.
Tab capture continues in the background as long as the meeting tab is open. However, some browsers throttle background tabs aggressively. Keep the meeting tab open (it does not need to be focused) and avoid closing it.
