AI race engineer for sim racing

A race engineer
in your ear.

Hold a button on your wheel and ask. bono reads your sim's telemetry live and answers on the radio: whether the energy lasts, who's catching you, when the rain comes, where the lap went. A spotter calls the cars around you the moment they're there.

A sample radio exchange. Pick a question to hear how the engineer answers.

A scripted sample. In the app you hold a button on your wheel and just talk.
Switch language or turn the sound on up top.

Engineer

Ask it anything about your race.

Energy, tyres, the cars around you, the weather, the clock, where the lap went: the engineer follows the whole race from the telemetry and answers in a sentence, like the voice on the pit wall. Pick a question to see what it looks at.

It answers from the whole race so far, not just the lap you're on. Turn the sound on up top to hear it.

Spotter

Calls the car beside you before you see it.

Cars alongside, three wide, flags, punctures and the weather turning: the spotter follows the telemetry and calls them by itself, the moment they happen. Pick a moment to hear it.

  1. Calls appear here as they happen

Calls come in the language you last spoke to the engineer in. Switch it on the radio up top, and turn the sound on to hear them.

Models

Pick the brain behind the radio.

bono works with the model you already use, on a server or on your own PC. Change it between sessions; the engineer just starts over.
