FOR STREAMERS · WINDOWS · OBS

A cohost who watches
the game, not the chat.

The Broker sits in your scene as one transparent Browser source and talks about what he sees in your game, in his own voice. He does not read chat and he does not need your microphone. This page says exactly what that means today.

NOW
  • One Browser source. Add your Broker to a stream or recording: the overlay shows his avatar and spoken captions on a transparent background. In OBS it is one Browser source at 800 × 600, placed above your game. The setup, step by step.
  • Three placements. Centered, Bottom left or Bottom right, with an adjustable dialogue size; preview the preset before copying.
  • His voice in your mix. He speaks through your Windows default output device, so Desktop Audio captures him together with the game. There is no separate audio track yet.
  • Two speech roles. SPECTATOR comments on what he sees; PLAYER speaks as if sitting beside you. Adjust Talkativeness.
  • Your controls. PAUSE holds the Broker without ending the session; RESUME continues it; STOP ends it. The Broker Bar shows time left and status, toggled with Ctrl + Shift + Alt + B.
  • Seven languages. Independent App Language and Broker Language: English, Bosnian Latin, German, French, Spanish, Italian and Portuguese.
  • Game knowledge first. The app identifies the game you chose, or asks you to name it, and loads what the Broker knows about that game before he starts.

What it does not do yet

  • Founder Alpha is early-access software: game capture, overlays and AI commentary can fail.
  • He does not hear you and does not read chat; the app has no microphone input and no chat.
  • No guaranteed cadence: how often he speaks depends on the game, the moment and the service.
  • Founder Alpha is available to customers in the United States only.
  • No chat reading, no alerts. He is not a chat bot or a text-to-speech reader; combine him with those tools if you want both. Options for a quiet stream.
  • No in-session game switching. To change game: STOP, choose the other game in the app, then START.

Tell your audience

The commentary is generated by AI. Say so on stream or in your description; some platforms and countries require it. What you record and publish is yours to manage; the Broker’s lines are AI-generated and should be labelled as such when published.

What it costs on stream

Streaming a session spends Signal Time exactly like playing without a stream. Signal Time is metered from the Broker’s managed AI work — every look at your game and every spoken line — rather than simply the elapsed time of your gameplay session. Your account shows usage and remaining balance.

  • Free trial.30 Signal Minutes (exactly 1,800 Signal Seconds), claimed through your eligible account. No card, purchase or subscription required; the trial never silently converts to paid.
  • Founder Alpha membership.$19.95 a month, including 5 Signal Hours per paid billing period. Additional Signal Time is $4.99 per Signal Hour and does not expire. Pricing.
