What Signal Broker is
Three lengths, every sentence copied from the product’s own pages. Use them as they are; the list underneath says what the current build takes in, puts out and does not do.

A real-time AI cohost for Windows gameplay and streaming: the Broker, a character with his own voice, watches the game you chose and speaks at the moments that matter. A 64-bit Windows application that runs on your PC. He observes, remembers what happened in the session, and speaks when it is worth it. Silence is a decision: he holds during cutscenes, dialogue and menus, and when nothing is worth a line. The app has no microphone input and no chat. Signal Broker comments on gameplay; he does not control it. A transparent overlay with guided OBS setup for your stream or recording. The Broker’s words and voice are generated by AI, and can be wrong or badly timed. Game capture, overlays and AI commentary can fail. Founder Alpha is early-access software. Founder Alpha is available to customers in the United States. 30 Signal Minutes. Free. No subscription or card required.
- Platform
- A 64-bit Windows application that runs on your PC. Founder Alpha for Windows x64.
- Status
- Founder Alpha is early-access software. Behaviour, wording and features change between builds. The service currently runs as a controlled pilot: only invited accounts are admitted, and the website says so when yours is not. Current public release: 1.0.0-alpha.12.
- Inputs
- While a session runs: captured frames of the game you chose, with the session context the Broker needs, go to the Signal Broker service and on to its AI provider to produce his observations and lines. Frames are processed in memory and are not stored by the service. Never: your microphone (the app has none), your password, other applications you did not choose.
- Outputs
- The Broker watches the game you chose and speaks through your default audio output. The Broker’s spoken line is shown as text in the app while he speaks. On stream: one transparent OBS Browser source for his avatar and captions, his voice through Desktop Audio.
- What it does not do
- He does not hear you. The app has no microphone input and no chat. Signal Broker comments on gameplay; he does not control it. The app does not stream anything itself; your streaming software captures what is on your PC. No in-session game switching.
- Commercial eligibility
- Founder Alpha is available to customers in the United States.
- 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. Signal Time measures Broker usage, not gameplay duration.
