Predictive Turn Analysis

Processes your telemetry in a rolling window as you drive. Exit a corner and feedback appears on screen within seconds - no lap completion required, no model download needed.

Works across all track layouts. Analyses throttle application, braking point, steering input, and corner speed on every recorded turn.

Post-Lap Deep Analysis

On-Device AI Coach (Experimental)

After each completed lap, the app segments your telemetry by corner and passes it to a 770 MB language model running entirely on your phone. The model produces coaching notes - critical, moderate, or minor - for each corner.

Covers throttle, braking, steering, and fuel. Analysis takes 15-60 seconds depending on device. Downloaded once over Wi-Fi from Settings.

How Predictive Analysis Works

1

Telemetry streams in at 60 Hz

Speed, throttle, brake, steering, and position data arrive from GT7 or AC over your local Wi-Fi network.

2

Corners are identified in real time

The app maps your position onto the recorded track layout and segments the stream into corner entries, apexes, and exits.

3

Feedback on corner exit

As soon as you leave a corner, the analysis result is displayed - no waiting for the lap to complete.

How the AI Coach Works

1

Lap completes

The app detects the finish line crossing and marks the lap boundary in the telemetry buffer.

2

Telemetry segmented by corner

The lap data is split into per-corner windows aligned to the recorded track layout.

3

On-device language model analyses each corner

The 770 MB model runs locally, reading throttle trace, braking, steering, and speed for each segment.

4

Coaching notes displayed

Notes are rated Critical, Moderate, or Minor and appear in the Lap History screen for review after the session.

What the Coach Analyses

▶

Throttle

Application point, smoothness on exit, and whether you are leaving time on the table by being too conservative mid-corner.

■

Braking

Braking point, trail-braking into the apex, and brake release smoothness. Identifies late or early braking patterns.

↻

Steering

Steering angle, smoothness through the corner, and whether inputs are abrupt or progressive.

▲

Fuel (GT7)

Fuel consumption per corner and whether aggressive inputs in certain sections are burning more fuel than necessary.

Common Questions

What is the difference between Predictive Analysis and the AI Coach?
Predictive Analysis is instant and runs in real time as you drive - no download needed. The AI Coach runs after each completed lap, uses a 770 MB on-device language model, and produces deeper narrative coaching notes per corner. Both are included in the subscription.
Does the AI Coach send my telemetry data anywhere?
No. The language model runs entirely on your phone. Your telemetry never leaves your device or your home network.
Do I need to download the AI model to use Predictive Analysis?
No. Predictive Turn Analysis works without any model download. The 770 MB download is only required for the experimental AI Coach mode and can be triggered from Settings at any time.
How long does AI Coach analysis take after a lap?
On a recent flagship phone (iPhone 14+ or equivalent Android), typically 15-30 seconds. On older hardware it may take up to a minute or more.
Does it work with Gran Turismo 7 and Assetto Corsa?
Yes. Both coaching modes - Predictive Analysis and the AI Coach - work with GT7 (Time Trial) and Assetto Corsa (Time Trial or Hotlap) on PlayStation 4 and 5.
