Twelve minutes of Grand Theft Auto V, playing as Michael, with the Broker narrating, recorded by the developer on a pre-alpha test build. An early recording of the character at work.
A real session: the developer playing GTA V on a Windows PC with Signal Broker running, the Broker watching the game window and commentating in his own voice. Nothing is scripted and nothing was re-recorded; what he says is what the build produced at the time, including the lines that miss.
A short gameplay featuring Michael from GTA V and Signal Broker as a narrator.
He is a character, not an assistant: you do not type to him and he does not wait to be asked. Silence is a decision he makes; the Broker Bar in the app shows LISTENING in that case. The same character ships in Founder Alpha today, with the current build’s capabilities and limits.
Moments from this recording
Read from the recording itself: the Broker’s words are what his overlay showed at that moment, the time is where the audio-derived captions place them, and “what the frame shows” is the game picture at that second. Hits and misses both count; nobody listened to the audio to write this.
4:30“Nothing happening”
uncertain The car is sitting in traffic, which fits “nothing happening”, but the street holds far more than two cars and a wanted level is showing.
GTA V recording at 4:30.
Ah, the sweet sound of nothing happening... just two cars contemplating existence.
What the frame shows. Michael’s chrome sports car in traffic on a busy street, with a motorcycle, several cars and pedestrians in view and a four-star wanted indicator at top right.
late Right about the death, but about twelve seconds after the WASTED screen.
GTA V recording at 5:58.
That was a sudden trip to the afterlife. Ouch.
What the frame shows. Michael is thrown from his car at 5:44 and the game shows WASTED at 5:46, while the bubble still carries his previous line about traffic rules; this line appears over the black screen that follows.
late Right about the bus, but the warning appears about a second before it hits him.
GTA V recording at 6:37.
That bus has other plans. Watch out!
What the frame shows. A city bus bears down on Michael as he walks in the road; the bubble appears at 6:37, the bus reaches him at about 6:38 and its front catches fire.
uncertain Someone is down after a crash, but the frames do not show whether it was a pedestrian, as he says, or the bike’s rider.
GTA V recording at 9:42.
That crash turned the pedestrian into a speed bump. Keep an eye out next time.
What the frame shows. A figure lies in the road and a red motorcycle lies on its side at 9:38–9:40; Michael lifts the bike and rides off as the line appears.
Recorded on a pre-alpha test build (“PRE-ALPHA TEST” in the upload title), playing as Michael, and reviewed from the 720p upload (1280 × 536).
This upload has no captions, so every time on this page is the moment the bubble appears in the frames, not a time taken from the audio.
His GTA lines are short one-liners: he reacts to the big visible events (a bus, a WASTED screen, a car coming at Michael), often a beat late, and misreads a car that stops.
Frames extracted from the recording (YouTube 81Ey9DDgCKs, 1280 × 536) every 5 seconds from 0:40 to 12:15 and every 0.5–2 seconds around each moment; words read from 3× crops of the overlay bubble; no captions exist for this upload, so timing is the bubble’s first appearance in the frames.
What this does not show
The commentary you hear was generated by AI on an earlier Founder Alpha build; wording, timing and voice behaviour change between builds. The current public release is 1.0.0-alpha.12.
A line can be wrong, repeated or badly timed. Quiet stretches are normal: silence is a decision the Broker makes.
This is a recording from the developer’s own play session. It is not a benchmark, a compatibility promise for this game or a measurement of how often he speaks.
The app has no microphone input and no chat: whatever the Broker says is a reaction to what he saw, not to the player’s voice.

Pick the game window, confirm the title, wait for Game Knowledge, tick Allow game capture and press START BROKER. PAUSE holds the Broker without ending the session: he stops looking and speaking until you press RESUME. There is no in-session game switching: to change game, STOP, choose the other game in the app, then START. The setup guide has every step; streamers add one Browser source in OBS.
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.
Founder Alpha is available to customers in the United States. Founder Alpha is early-access software. Signal Broker is an AI system. The Broker's words and voice are generated using AI. No person is speaking or writing what he says.
