PITWATCH

BUILT FOR ACC & LE MANS ULTIMATE

An engineer on your radio,
every single lap.

PitWatch watches your telemetry so you don't have to. Ask it anything mid-session, and it speaks up on its own the moment something changes the race.

You're already at the limit. You don't have a spare glance for a dashboard, and you definitely don't have a spare hand.

Overlays make you look away from the track to read them.
Spotter apps tell you what's happening, not what it means.
By the time you've processed a number, the corner's gone.

HOW IT WORKS

Three systems, one radio channel.

Telemetry in, reasoning in the middle, a voice back out — the same loop a real race engineer runs, just running constantly and never getting tired.

Telemetry, straight from the sim

PitWatch reads ACC and Le Mans Ultimate's shared memory directly — position, damage, fuel, tyre wear — with nothing installed on the sim side and no ports exposed.

→ feeds the engineer

An engineer that actually reasons

Every frame runs through the Gemini API. PitWatch isn't replaying canned lines — it's weighing what just happened against what mattered, lap by lap.

→ decides what to say

Ask it, out loud

Just ask your question out loud — PitWatch listens, understands, and answers back on the radio. No typing, no alt-tabbing.

→ speaks on the radio

FEATURES

Everything a good engineer would tell you.

PitWatch doesn't wait to be asked for the things that matter most — it calls them the moment they happen.

Overtake commentary

Calls the pass as it happens — who, where, and what position you're in now, without you having to check a leaderboard.

Crash & contact detection

Flags contact the instant it happens, so you know if it's worth a look before the next braking zone.

Damage callouts

Tells you what broke and whether it's safe to keep pushing — not just that something happened.

Race finish messages

A proper radio sign-off when you take the flag — your finishing position and the shape of the race that got you there.

Push-to-talk Q&A

Ask "what position am I in" or "how much fuel have I got" out loud, and hear the answer straight away.

Built for ACC & LMU

Native shared-memory support for Assetto Corsa Competizione and Le Mans Ultimate today, with more sims planned.

HEAR IT IN ACTION

A lap, replayed over the radio.

A sample exchange from a real test session — PitWatch calling the race unprompted, then answering a question mid-corner.

FIRST TEST · SPA-FRANCORCHAMPS

It's already turned laps for real.

Before any of this was a landing page, it was a driver alone in a sim with a live mic and a hunch. The first full test session ran clean end to end — telemetry in, callouts out, no missed radio.

Shared-memory telemetry held for the full race distance

Overtakes and contact called without a prompt

Push-to-talk questions answered mid-session

Finish message delivered as the flag dropped

LIVE NOW

Grab PitWatch and start racing.

One installer — plug in, and you've got an engineer on the radio, every lap.

What do I need to run it?

ACC or Le Mans Ultimate on PC. Just talk — PitWatch handles voice input on its own, no typing or dictation needed. A second monitor is recommended for keeping an eye on PitWatch's window, but it isn't required.

Does this replace my spotter overlay?

No — it replaces the need to look at one. PitWatch is built to be heard, not read, so your eyes stay on the track.

Where does my telemetry go?

Telemetry is read locally from the sim's shared memory. Only the race context PitWatch needs to answer or call something is sent out for reasoning.

Which sims are supported?

Assetto Corsa Competizione is fully supported today, with Le Mans Ultimate in active testing. More sims are planned after launch.

Does PitWatch cost anything?

No — PitWatch is free for now. If that ever changes down the line, you'll hear about it here first.

Do I need an internet connection?

Yes. Telemetry is read locally, but the reasoning behind every callout runs through the Gemini API, so PitWatch needs a connection to actually think.

Will it slow down my sim or add input lag?

No. PitWatch runs as its own background process reading shared memory — it never touches your inputs or rendering, so there's no effect on frame time or car control.

Can I make it talk more or less?

Yes. You set how chatty PitWatch is on the setup page before you head out, and you can just tell it to talk more or less at any point mid-session.

Does it help with fuel and pit strategy?

Yes. PitWatch tracks fuel burn as you drive and can talk you through stint length and pit windows as the race unfolds.

Does it know my sector times and pace, not just my position?

Yes. It watches your sector splits and pace in real time — that's what it uses to call your overtakes as they happen.

Can I ask about other drivers, not just my own car?

Not yet. PitWatch currently reasons about your own car — position, pace, fuel, damage. Gap-to-rival data and full opponent awareness aren't there yet.

Will there be a mobile companion app?

Not for the initial release. Everything runs on the same PC as your sim, so there's nothing extra to install on a phone.

What happens if my connection drops mid-session?

Telemetry keeps reading locally either way — you won't lose position or lap data. Spoken callouts just pause until the connection is back.

What languages does it speak?

English. That's the only language PitWatch speaks right now.

Where can I follow along or ask questions?

Our Discord is the best place — that's where launch updates, testing notes, and questions get answered directly.

Can I contact the founder directly?

Yes — email balazs.kiss@pitwatchai.com any time.

Why did Windows show the SmartScreen warning?

PitWatch is safe. It's just new — Windows flags any app that hasn't built up download volume yet, regardless of what it does. And you don't have to take our word for it: PitWatch is fully open source, so anyone can check the code themselves on GitHub.

Your next session deserves an engineer.
