How it works
Three taps from stock to show car
No sliders, no masks, no layers. You choose what you want on the car; the studio does the bodywork.
Pick the parts
Up to three parts per build: a finish, a wheel design, a wing, a widebody kit, carbon panels, headlights, a livery or a new environment.
Build and keep going
The result becomes your new base car. Stack more parts on it, retry, save to photos or open it later from your garage.
Parts catalogue
Every mod, rendered on your car
Each part is applied to your exact car: same body, same angle, same light. Only what you asked for changes.
Paint
Solid, metallic, pearl, matte and candy finishes.
Rims
Sport, classic and concept wheel designs, fitted to size.
Spoilers
From subtle lip spoilers to full GT wings.
Carbon fiber
Hoods, roofs, mirrors, diffusers or the whole kit.
Body kits
Widebody kits that keep your car's silhouette recognisable.
Headlights
LED and DRL signatures adapted to your housings.
Liveries
Racing stripes, sponsor decals and side graphics.
Environments
Relit and reshadowed in a new location, not pasted on.
Scene presets
Drop your car into a scene
One tap, one flat price. Traffic cam, police chase, drift night, toy-car packaging, game HUD and more, each built around your car.
Inside the studio
Built like a garage, not a filter app
Dark, fast, tactile. Every screen is designed around the car in front of you.
Build summary
See what is on the car before you spend a credit, remove parts with a tap.
Stackable builds
Each result becomes the next base. Paint first, wheels next, then the kit.
Retry anytime
Not the wing you pictured? Rebuild from the same photo with the same parts.
My garage
Every build, saved in the cloud

Auto-saved
No save button to forget. Every successful build lands in your garage.
Favourites
Star the builds you love and filter to them in a tap.
Continue editing
Pick any saved build and keep stacking parts on it.
