    How it works

    Fast where it has to be. Smart everywhere else.

    What has to be instant runs on your PC. What needs judgement goes to the engineer in the cloud. You hear one engineer either way.

    1. Install on your sim PC

      A small Windows app that reads the game's telemetry while you drive.

    2. Pick your language

      English or Brazilian Portuguese, on the radio and in the app. The engineer comes on with a radio check.

    3. Race

      Calls arrive when they matter, and stay away when they don't.

    On your PC, instant

    The spotter never waits for the internet

    • Car left, car right, three wide, clear
    • Green, blue and chequered flags, full course yellow
    • Contact, with the car you hit by name
    • Pit lane limiter

    Under 100 ms. No internet needed.

    In the cloud, smart

    The engineer knows your race

    • Your place in class, gaps and rivals by name
    • Your pace against the cars around you, fuel, the last lap
    • Where you lost time last lap, and the fix
    • How to pass: the exit, the tow, the inside line
    • Your pit window and where you rejoin
    • Rivals in the pits, a free stop under yellow, rain coming
    • A check-in after a hit, and what it cost you
    • An honest debrief at the flag

    Every number comes from your telemetry and is checked before it's spoken.

    Moments of a race

    Five calls, in the voice you get on track.

    Start

    Green, green, green!

    Lights out, right on the call.

    Fight

    Three wide, you're in the middle.

    The spotter has your mirrors.

    Incident

    Contact! We have damage, check the car.

    Read from the car's damage data.

    Pit stop

    Pit lane! Limiter, limiter!

    Forgot the limiter? Not for long.

    Finish

    Checkered flag! Good job, bring it home.

    Then an honest debrief.

    On the radio

    Calls that change your race.

    Not chatter: the gap to the car behind, when to box, who is coming through. Lines from our own races and the app's calls, as you'd hear them.

    Talk back

    Ask your engineer.

    New · beta

    Tap a button on your wheel and ask in your own words. Gaps, position, time left, last lap and fuel come back in about a second; anything else takes two or three. Every answer comes from your live race and is checked like any other line.

    • What's the gap to Lietz?
    • How many laps of fuel?
    • Where am I losing time?
    • Say again.

    Settings → Audio: turn push-to-talk on and press the button you want.

    Languages

    Written for the radio in each language.

    Each language is written the way an engineer from there talks, not translated line by line. The app itself speaks Portuguese too, not just the radio.

    • Big hit. You OK? Can you keep going?Engineer

    Português (BR)

    FAQ

    Questions.

    Does it talk over me?

    No. Every line goes through one queue on your PC: urgent spotter calls first, everything else waits for a straight and is dropped if it's no longer true. It never repeats itself, and after a big hit it checks on you once.

    Does it need internet?

    The spotter, flags, contact and pit limiter calls run on your PC and work offline. The engineer (strategy, rivals, the debrief) needs a connection.

    Will it make things up?

    No. The engineer only gets numbers from your telemetry, and every line is checked against them before it's spoken. If something stops being true before there's a moment to say it, it isn't said. And once it tells you to box, it won't say stay out a few seconds later unless something new happened.

    Can I ask it things?

    Yes, in beta. Turn on push-to-talk in Settings → Audio, pick a button on your wheel, tap it and ask. Gaps, position, time left, last lap and fuel come back in about a second; anything else goes to the AI and takes two or three. "Say again" and "quiet" work too.

    Where are my races?

    In your account. Every race is saved with its result, laps, driving charts and what the engineer said, on any PC you sign in to.

    Which sims?

    Le Mans Ultimate on Windows today. iRacing is next.

    What does it cost?

    RaceBuddy will be a paid subscription, because the AI engineer costs money to run. Pricing isn't set yet. Every account gets trial credits for about 10 races a month.

    Is it like the spotter apps I already use?

    For calls that must be instant, it works the same way: local rules and pre-recorded voice. On top of that you get an engineer who understands the race, knows your rivals by name, and sounds like a person.
