“All good ideas start out as bad ideas, that’s why it takes so long.”

—Steven Spielberg

for UI specs

UI Drafter is not a graphic design or no-code development tool. It's for pre‑production, inspired by how screenwriters write movies and TV scripts.

With it, product managers and domain experts experiment with, and communicate exactly what they're trying to achieve in a highly malleable and affordable medium.

more directly

Traditionally, domain experts teach their business, from A to Z, to software designers. Now anyone can spec out software requirements and improvements in a few steps.

Draft without
graphic design

Unlike wireframing, brainstorm with without space constraints.

No screen-sizes. No 2D layout.

Just the content and its flow.

Software Engineering a UI


See more angles by trying out groupings, orderings, and variants on the fly.

Redesigning UI


Concretize ideas and get more realistic usability feedback than by testing mockups.

Mockups are better suited for evaluating style, layout, and animations, because they induce unnatural awareness into the test subject. For example, by requiring more memorization and imagination.

Conditional Options

Create dynamic sub-categories.

Chained Selectors with dynamic sets of options

Computed Forms

Integrate UI elements in formulas.

Formulas using UI Elements

Help Designers

Given a UI Drafter prototype, designers can lay out knowing what to organize. Therefore, it makes the design phase feel like a redesign one, familiar and straightforward.

Tip: Print the prototype as PDF and edit it in a graphic design program.

Mitigate Rework

As UI Drafter presupposes graphic design and development, you can focus on the fundamental interface elements with more mental room.
