Design circuits.
Analyse performance.
Build better tracks.
Sketch a circuit centreline and get instant scoring on safety, overtaking potential, and fun — plus an estimated circuit grade based on published guidelines. Free to use.
The problem
Most track designs never get proper analysis
Professional circuit design consultancy costs tens of thousands. CAD tools are complex. Most enthusiast designs never get feedback on whether they'd actually work.
How it works
Three steps to a better circuit
Draw your track
Click to place points and create a smooth spline centreline. Overlay on a satellite map or trace over an image.
Get instant analysis
Our engine scores your layout across safety, overtaking potential, and fun/flow — with an estimated circuit grade. Instantly.
Refine and export
Get AI commentary comparing your design to real circuits. Export a professional PDF report for stakeholders.
Features
Everything you need for circuit design
Spline Drawing Tool
Click-to-draw with smooth Catmull-Rom splines. Undo, redo, close circuit. Real-time track width visualisation.
Satellite Map Overlay
Draw directly on Mapbox satellite imagery. Design street circuits or overlay on existing venues.
Multi-Score Analysis
Safety, overtaking potential, fun/flow, and estimated circuit grade (1–4). Each scored 0–100 with detailed breakdowns.
AI Design Commentary
AI compares your layout to real-world circuits and suggests improvements based on motorsport design principles.
See it in action
Concrete analysis, not vague scores
Every track gets AI commentary comparing your layout to real circuits, plus physics-based lap simulation across four car classes.
AI Design Commentary
ProThis layout shares DNA with several celebrated circuits. The opening sequence of fast-to-medium corners echoes the Maggots-Becketts-Chapel complex at Silverstone — alternating direction changes at speed that reward commitment and punish hesitation.
The main straight at 780m provides a genuine overtaking opportunity, comparable to the back straight at Circuit de Barcelona-Catalunya. With a heavy braking zone into a tight right-hander, this is where most position changes will happen.
The final sector's elevation-blind apex is reminiscent of Eau Rouge/Raidillon at Spa — a signature moment that will define the circuit's character.
Suggestion: Tightening Turn 6 by 15% would create a stronger second overtaking zone without compromising flow.
