TanLens for Microsoft Edge: live tab captions

Add the TanLens MV3 extension to Edge, capture a tab’s audio, and read translated captions over meetings, streams and web players.

TanLens works in Microsoft Edge through the same Manifest V3 extension used in Chrome. Edge is Chromium-based, so tab capture, the caption panel and the web app behave the same way once the extension is installed and connected to your account. Nothing changes on the meeting platform side; Edge captures the audio that the tab is already playing.

01The same extension, a different browser

Open edge://extensions, enable Developer mode, and load the TanLens extension package the same way you would in Chrome. Sign in from the extension popup, keep the meeting or video tab active, and press Start. Edge uses the same tabCapture permission as Chrome, so the active tab’s sound becomes captions; no separate sharing dialog is involved. Edge’s built-in page translation does not touch live audio, so it is not a substitute for TanLens.

02Managed Edge profiles at work

Many organizations manage Edge through group policy, and those policies can block unpacked extensions or restrict which sites may capture audio. If the extension disappears after a restart, or the Start button does nothing, the browser profile is the likely cause. Ask your administrator rather than trying to work around the policy. On a personal profile, the usual limits still apply: DRM sites may block tab audio, native apps are not tabs, and microphone sessions need separate permission.
