Record a Slack huddle with every face

Record a customer call or a team demo in Slack with every face in view, not only yours. Fix one voice later without touching the others.

How to record it

  1. In Bingsu’s menu bar panel, choose Window and pick the Slack huddle.
  2. Bingsu finds each person in the call and adds them as a bubble: up to 4 guests, plus your camera.
  3. Pick one bubble for whoever is speaking, or one bubble per guest. Drag, resize, reshape or hide any of them.

Which window Bingsu looks for

The Slack window titled with “Huddle”. A guest gets a bubble when they share their camera; a huddle without cameras records their voices only.

Any other window works too: choose Find faces in this window.

The sound

Each guest’s voice comes from Slack’s own sound, on a track of its own. Yours comes from your microphone. Set each track’s level later, or press Balance. Faces and voices are found on your computer; nothing is uploaded.

From an agent

An agent you have allowed can record the call with the same bubbles:

bingsu record --face call=slack,follow=speaker

Over MCP, bingsu_start takes "faces": [{"call": "slack", "follow": "speaker"}].

Tell everyone on the call that you are recording. In many places the law requires their consent.

Every call app

Next time, show it.

Record it once and send a link. Or let your agent do the recording.
