Stop AI-generated UI from looking AI-generated.

AI design slop is the generic interface an agent produces when the brief leaves every visual decision open. Avoid the clichés before they reach a pull request, with a DESIGN.md that gives the agent your actual defaults.

The problem is not that a violet accent, a rounded card or an emoji is always wrong. It is using them by default, without a reason the product can defend.

Generic is what an agent chooses when your brand is absent.

Most AI-generated UI is not broken. It is worse than that: it is competent, generic and interchangeable. The same violet flourish, the same rounded card grid and the same frictionless marketing language appear because an agent must choose something when the product gives it nothing to follow.

Treat those patterns as symptoms, not a style crime. A purple gradient can be right for a purple-gradient brand. The real failure is an agent choosing it because no design decision was available. DESIGN.md gives it the decision before it writes the screen.

One file, the decisions agents need.

Specific visual defaults

Give agents your actual palette, dark theme, typography, shape, depth and icon set before they reach for the most familiar version of each.

A list of deliberate noes

Record the clichés that do not fit your product, so avoiding them is a project rule rather than a review comment.

A voice with a point of view

Set expectations for product language too. Generic UI is as much filler copy as it is violet accents and floating cards.

Built for the way agents read a project.

1
Name the defaults you keep rejecting.
Watch for vague claims, decorative gradients, emoji as interface icons, excessive rounding and repeated card grids. Keep only what has a product reason.
2
Replace taste with a readable decision.
An agent cannot implement “make it feel more like us.” It can implement a named color scale, a type system, an elevation rule and a copy style.
3
Put the decisions in every agent task.
Store DESIGN.md with your repository instructions. The next feature begins with your constraints instead of the model’s most probable interface.

The cure for AI design slop is context, not a longer prompt.

Start with the decisions your product already has, read straight from your website. Onefold turns them into the design context that stops every new prompt from falling back to the average.
