Describe a Roblox UI. Veritas designs it, shows it on every screen size, and hands you a model file to drag straight into Studio. Pick a look to start from, or add screenshots of a style you like.
UI and UI behaviour only: no server scripts or whole games.
Your UI appears here as it is drawn.
Getting it into Studio
Press Download for Studio. You get one .rbxmx model file.
Drag the file into the Roblox Studio viewport (or right-click StarterGui and choose Insert from File).
If it landed in Workspace, move the ScreenGui into StarterGui.
Press Play. The UI scales itself to phones, tablets, consoles and desktops, and its buttons, windows, tabs and toggles already work.
Dashed boxes are blank image slots, named after what belongs in them: select one in Studio and set its Image to your own art. Connect your game's logic to the buttons from your own scripts.
Veritas-Flash is quick and good for most windows. Veritas-Skilled plans the design, draws it, then checks it on a laptop and a phone and corrects what it finds: slower, with fewer per day.
