DiffUI: UI designs from a prompt

Official site link, not an affiliate link. We do not have an approved referral link for DiffUI.

DiffUI turns a written prompt into UI design options for a product screen or a marketing page. You can also upload screenshots so later screens follow the same colors, type, spacing, and components. You pay per generated image. The pricing page does not list a free generation allowance.

What it does

DiffUI is an AI design tool for interface directions. You describe the screen you want, and it generates design images you can compare. The homepage states that a prompt produces 9 options in about 50 seconds. That figure is the company’s claim, not a measurement from this site.

If you already have a product, you can upload screenshots. DiffUI says it reads colors, fonts, spacing, and components from those images, then generates new screens that match. The page aimed at bootstrapped app makers says one prompt can return nine distinct visual directions, and that screenshots can be used as style references.

From a chosen direction, DiffUI says it can extract a design system: colors, fonts, space, and radius become tokens, wrapped in vanilla Web Components, with no framework lock-in. It also says it can turn the designs into usable responsive code. The pricing page says that design-to-code step is free while the product is in beta, and that you pay for the images you generate.

Official site: diffui.ai.

Who it’s for

DiffUI fits product people, designers, and small teams who want several on-brand UI directions from a prompt, and who prefer to pay per image instead of adding another monthly design seat. The company also addresses bootstrapped web-app makers who want the product to look considered before they have a design department.

A good fit: you need interface options for an app or a page, you may already have screens to match, and you want to pay only when you generate an image.
A weaker fit: you need a shared design file, prototypes, and developer handoff in a tool the whole team already lives in. Figma is the closer match in this library for that job. If you want a published website from a visual builder, look at Framer or Webflow.
