About Us
Mason turns the roughest thing you can draw into a finished interface. Rectangles on a canvas become a real screen, built from a design system read out of your own mood board.
It starts with a mood board and ends with something you can move, resize and argue with. No prompt engineering, no blank page — you draw the shape you already have in your head, and the parts that are tedious rather than creative get done for you.
Our Philosophy
Most tools ask you to describe a screen in a sentence. We think you should draw it. A sketch carries layout, proportion and reading order in a way no paragraph does — so we read the shape you made and let the words do the part they are good at, which is saying what a thing means.
Our Values
Structure First
A layout is a decision, not a guess. The sketch you draw is what decides the screen — the model fills it in, it does not invent it.
Systems, Not Screens
Colour and type are bound to roles before anything is drawn, so the fifth screen still belongs to the same product as the first.
Legibility Is Not Optional
Every foreground is checked against the surface it sits on. A palette that reads beautifully and fails a contrast pairing is not finished.
Show The Work
Designs stream in as they are written. You should be able to tell a run is going wrong in seconds, not after the full minute.
Nothing Is Precious
Everything autosaves, a drag is one undo step, and a revision that fails puts back the design you already had.
Mason was built in the open, chapter by chapter, and the parts that were hard are written up on the blog — why a labelled box beats a better prompt, why a palette is a set of constraints, and what it takes to stream a design into existence without it flickering.
