DiffUI
DiffUI is an AI tool that generates new UI designs matching your product's existing look, then turns those designs into real, responsive code.

Description
Adding a new feature to a product usually means either hiring a designer to mock it up in your existing visual style, or letting an engineer wing it and hoping it doesn't look out of place next to the rest of the app. DiffUI tries to shortcut that: you upload screenshots of your product, it learns your visual language — colors, fonts, spacing, the general feel — and then when you describe a new feature or screen, it generates several design options that actually look like they belong in your product, not a generic AI-generated interface.
Technically, DiffUI extracts design tokens automatically from the screenshots you provide (colors, fonts, spacing, corner radii) and generates around 9 design options in roughly 50 seconds per prompt. Once you pick a direction, it can convert the design into responsive, production-ready code using vanilla Web Components, which keeps the output framework-agnostic rather than locked to React, Vue, or any single stack. Pricing is usage-based: Individual tier runs about 17 cents per design generation pay-as-you-go with no minimum, Team tier is 22 cents per generation with a $50/month minimum, and Enterprise is 26 cents per generation with a $300/month minimum; the design-to-code conversion feature is currently free while in beta, and individual build assets like images or background removal are priced separately at 1-17 cents each.
💬 Our review
The short version: for teams that need new UI mockups to genuinely match an existing design system rather than looking like generic AI output, DiffUI's brand-learning approach and framework-agnostic Web Components output are a real differentiator over prompt-to-UI tools that ignore your existing visual language entirely. The usage-based pricing means you only pay for what you generate rather than a flat monthly seat fee.
The honest tradeoff is that per-generation pricing can add up fast for teams iterating heavily — 9 options at 17-26 cents each per prompt, multiplied across many prompts during active design exploration, isn't necessarily cheaper than a flat-fee tool like Figma AI features bundled into an existing Figma subscription, or a human designer on retainer for teams doing continuous heavy design work. It's a strong fit for occasional, well-defined generation needs (a new feature screen, a landing page variant) and less clearly cost-effective for teams that would generate dozens of options daily.
