Real life race drivers always have someone on the radio. A race engineer reads the telemetry, does the math mid-race, and tells the driver what matters when it matters: fuel, tires, gaps, strategy. The driver drives; the engineer talks.

Sim racers, though, just have dashboards. Games like GT7 stream their live telemetry, and a healthy ecosystem of second-screen apps renders it on a phone next to your wheel. Some of those dashboards are genuinely cool: they look great, and they work. But most of their numbers only help if you look at them, at the right moment, and do the math in your head. Doing that while racing might be harder than racing itself!

So we built the thing we wanted: not another dashboard, but a co-driver. Today we're releasing it as a closed beta. Its name is Guido.

Guido speaks Gran Turismo 7 today because we wanted to get this out the door as quickly as possible. More sims are coming: Le Mans Ultimate is the most likely next one, with the Assetto Corsa family a candidate for the same release, and more queued up behind those. We chose GT7 as a starting point for two reasons:

  • GT7 is underserved compared to other games (to be fair, it's harder to make things work on PS4/PS5).
  • When we got started with sim racing, GT7 was our first game and we wanted to pay homage to the game that got us started.

A polished dashboard

Guido turns a spare phone or tablet into a full-screen, landscape race dashboard: a 16-LED rev bar with shift lights, a gear and speed readout big enough to parse with peripheral vision, per-tire temperature gradients, red downshift cues beside the gear indicator, and the live status of your assists.

We like apps that just work so Guido finds active sims on the network on its own. Turn on your sim and you're good to go.

Now while this is nice, we do know there are other amazing dashboards out there (in fact we love them as well!) but that's not the core feature of Guido. What makes it special is that you can just talk to it and it'll talk back!

The engineer in your ear

Guido watches the race the way an engineer would. As the telemetry streams in, it builds a model of your session: which lap you're on, how much fuel the car actually burns per lap and how many laps the tank will stretch to. When the math stops working in your favor, it speaks up: "Box this lap."

It goes both ways, too. Hold the push-to-talk button and ask. How much fuel is left? How many laps to go? What's the advice? Guido answers out loud, in plain English, while your hands stay on the wheel. It's also polite about it: if you just asked about fuel, it won't interrupt you a lap later to say the thing you already know.

If you're concerned about your data: none of that leaves your Wi-Fi. The speech recognition runs on your device, the telemetry runs on your network, and there is no cloud in the middle. Your races belong to you. And unless you sign in for Pro, we don't even know your email!

Free and Pro

The dashboard, push-to-talk, and the calls Guido makes on its own are free. No account needed.

Signing in with an email unlocks Pro, free while we're in beta. It adds hands-free voice activation: with the "hey Guido!" trigger word you just talk to Guido instead of reaching for a button.

Join the closed beta and Pro stays free for 6 months after the public launch.

What's next

Guido speaks GT7 today, and it's not staying monolingual for long: Le Mans Ultimate is the most likely next stop, quite possibly with the Assetto Corsa family in the same release, with F1 and iRacing queued up behind those. The engineer keeps learning too: tire and shift intelligence, richer race strategy, more questions it can answer. The roadmap on the product page stays current as that lands.

Get in

Guido is in closed beta on Android, so the store listing isn't public yet. Join the beta and we'll send your invite as soon as there's room — and tell you the moment iPhone support or a new sim lands.

You're on the list. We'll email you as soon as there's room.

No spam. One email when there is news.

If you race, tell us what Guido should learn next. We read everything at hello@matto.club.
