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.
Start from a template
Don't start from a blank canvas
Pick a pre-built layout and make it your own. Each template is fully editable — adjust corners, widen the track, add pit lanes, and get scored instantly.
Simple Loop
A basic closed circuit with gentle curves. The perfect starting point — modify it to learn how each change affects the analysis.
High-Speed GP
Long straights with heavy braking zones and fast sweepers. Inspired by classic F1 power circuits.
Street Circuit
Tight 90-degree corners, narrow streets, and short straights. Think Monaco or Singapore.
Oval Speedway
Classic oval with banked turns. Simple, fast, and all about speed and bravery.
Figure-8 Circuit
A crossover layout with an overpass. Great for kart tracks and creative designs.
Technical Circuit
Flowing S-curves, elevation-friendly corners, and varied radii. Rewards driver skill over raw power.
Roval
An oval with an infield road course section. Combines NASCAR-style banking with technical corners.
Kart Circuit
Compact layout with tight hairpins and quick direction changes. Perfect for karting or small-scale tracks.
Hill Climb Sprint
A point-to-point hill climb course with elevation-friendly switchbacks, hairpins, and a fast summit approach.
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.
