Your Race Engineer powered by AI

Apex Engineer listens to you, reads live telemetry and answers like a real trackside engineer. Fuel, tyres, damage, strategy — spoken to you in real time while you drive.

Live telemetry

Your race, read in real time

Apex Engineer reads the same data your pit wall would — and turns it into calls you hear mid-corner.

SimHub link at 20 Hz

Fuel, tyres, temps, damage and gaps streamed in live.

Measured, not estimated

Fuel burned per lap is computed from real sensor data, lap after lap.

Real degradation curves

Tyre wear tracked per wheel so pit windows land exactly when they should.

Pit lane & deltas

Know the real cost of a stop and the live gap to every rival on track.

The pit wall

Todas las herramientas que necesitas para ganar tu próxima carrera HOY

A full engineering team on your shoulder — reading the same telemetry, calling the same calls.

Live AI race engineer

Talk over the radio with push-to-talk. It hears you, reads live telemetry and replies by voice in real time — calm, concise, human.

Chief strategist

A background macro-strategist computes stints, pit windows and race phases, and pushes updates to your engineer automatically.

Real-time telemetry

Connects to SimHub at 20 Hz: fuel, tyres, temperatures, damage, sector deltas, gaps and pit lane time cost — measured, not guessed.

Fuel & tyre management

Measured litres per lap and real degradation curves decide lift-and-coast, stint length and the right window to box.

Damage detection

Critical damage triggers an instant, network-independent “Box, box” call — even if the LLM API is down. A safety net that never sleeps.

Your choice of LLM

Bring your own key from Groq, OpenAI, Gemini, Mistral or Claude. Separate engineer, strategist and voice providers to split quotas.

On the grid

Ready in three steps

01

Connect your sim

Run SimHub, select your simulator and pick your microphone and speaker. Apex reads the live telemetry stream from the game.

02

Configure your AI

Choose your LLM provider and paste your API key. You can mix engineer, strategist and voice providers to split quotas.

03

Race

Generate a pre-race strategy, then press start. Your engineer is on the radio from lap one — strategy, alerts and answers live.

Frequently asked questions

Which simulators does Apex Engineer support?

iRacing, Assetto Corsa, Assetto Corsa Competizione, Le Mans Ultimate and rFactor 2 — anything that feeds telemetry to SimHub.

Do I need my own API keys?

Yes. You configure your own keys for the engineer, strategist and voice transcription. This keeps costs predictable and lets you choose your favourite provider.

How much does the AI cost per race?

A full 8-hour endurance race is roughly 1.35M input tokens and 132k output tokens in total. With low-cost models like Groq or Mistral that is a fraction of a cent per race.

Does it work with a steering wheel button?

Yes. Push-to-talk maps to a keyboard key or any button on your USB wheel or joystick.

Can I cancel my subscription?

Anytime, from your Lemon Squeezy customer portal. You keep the software until the end of the billing period.

Does it work offline?

The engineer needs its LLM provider, but critical safety calls — like “box, box” on heavy damage — are spoken from a local cache even when the network fails.
