# Capturing calls

<View title="macOS" icon="apple">
  <Warning>
    Tuple's local Capture feature is in **alpha**. Aspects of the feature might change as we continue to iterate on feedback.
  </Warning>

  Capture streams what happens on a call to your **local disk**: a transcript of what's said, recordings of any screen that gets shared, and metadata for apps on shared screens. It runs **entirely on your machine**; nothing gets sent to an external service.

  Capturing calls enables two things: it lets agents follow the call in real time, and allows you to reference information from past calls.

  ## Starting and stopping capture

  The **Capture** button appears in the popover, the screen share window, and the webcam window:

  When the popover is focused during a call, **C** toggles capture. See [Using your keyboard to navigate Tuple](/pairing-with-tuple/using-your-keyboard-to-navigate-tuple).

  You can also have Tuple start capturing as soon as you join any call; see [Start capture automatically](/application-preferences/macos-preferences-capture#start-capture-automatically).

  ## What Capture records

  A captured call contains three kinds of content:

  * **Transcript**: everything said on a call, transcribed by a local Whisper model.
  * **Screen recordings**: recordings of any screen that gets shared on a call (yours or someone else's).
  * **App metadata**: window titles and content URLs for the apps visible in shared screens; learn more about [what gets broadcast](/pairing-with-tuple/broadcasting-app-metadata).

  ## Notifying other participants

  When you start capturing, every other participant receives a notification letting them know. The notice stays on screen until the participant acknowledges it or leaves the call. If you join a call that's already being captured, you'll receive the same notification.

  While capture is active, each capturing participant shows a **Capturing** indicator in the popover participant list and in the screen share window's participant list.

  ### Capturing solo

  You can capture a call by yourself, even before any other participants have joined. This is useful for capturing notes, dictation, or working with an agent (see [Connecting an agent](#connecting-an-agent)).

  ## The capture panel

  The chevron next to the **Capture** button opens the capture panel, which shows what's being captured right now and how to hand it to an agent:

  While capture is running, the panel shows:

  * The most recent line of transcript, attributed to whoever said it.
  * Which screen is being recorded, and the focused app on it.

  ## Accessing captured calls

  Captured call content is stored in a local database on your machine. You can browse captured calls in the [Local History](/pairing-with-tuple/local-call-history) tab, or use the `tuple` CLI to search, list, and export past calls — see [Searching past calls](/pairing-with-tuple/searching-past-calls).

  ## Automating with triggers

  Tuple fires `call-transcription-started` and `call-transcription-complete` [triggers](/triggers/api-reference) when a capture session begins and ends. Use a trigger script to post-process transcripts, summarize the call, or save it into your team's notes system.

  Browse the [Triggers Directory](https://tuple.app/triggers/directory?event=call-transcription-started\&event=call-transcription-complete) to see what others have built.
