Ship generative UI in week one.

GenUI Kit by VGV drops AI-generated, on-brand interfaces into the Flutter app you already have. Bounded zones, your design system, real data. The hard GenUI lessons, compressed into your first week.

The prompt input that drives the generated interface

Text is a dead end for agents.

An agent that answers in paragraphs makes the user do the mapping, from what they want to the taps the UI demands. An agent that answers in UI maps itself to the task. That is the shift GenUI makes real, and the one most teams learn the hard way.

"Where's the agent that speaks in widgets rather than in text? It's the difference between me mapping what I'm trying to do to the taps required by the UI, versus the UI mapping itself to what I'm trying to accomplish."
Andrew, Flutter team at Google

The product

A starter kit for GenUI, not a science project.

GenUI Kit drops generative surfaces into controlled zones inside your existing app. A zone is a bounded place where a personalized, on-brand surface renders from your own design system and real data. The app still owns navigation, fallbacks, and rollout. GenUI owns the surface inside the zone. Customer-hosted, full source, Flutter-first.

Catalog conversion

Turn your design system into a locked, brand-safe component catalog the model can compose from. Generated like data, safe like code.

Developer cockpit

Run, inspect, and replay every generation. See exactly what the model chose, why, and what it rendered before it ships.

Real backend tools

Wire generations to your live data and services, not mock JSON. Surfaces render from the real backend your app already runs on.

Quality gates and repair

Schema validation, accessibility linting, and brand checks on every tree. Anything that fails falls back to a deterministic component.

Enterprise buyers want bounded areas with kill switches, fallbacks, and measurement. Zones give them exactly that.

Kill switches Deterministic fallbacks Built-in measurement

How it works

The model orchestrates. It never paints pixels.

The LLM never generates raw UI code. It selects components from a pre-validated catalog, which are formally assembled and rendered by the Flutter GenUI SDK over the A2UI protocol. Three inputs govern every generation.

01

System prompt

The operational logic of the agent. Rules, tone, and constraints that align every generated surface with your brand and business intent.

02

User context

Intent, preferences, and state, bound to the catalog so the model can assemble an experience tailored to the moment.

03

Catalog items

The vocabulary of the system. The approved components and patterns the agent is allowed to use, and nothing else.

Governed by VGV's proprietary Adaptive Experiences method

We partner with your team to define a custom Generative Design System, then build the AI-driven architecture that powers it in production. The fluidity of AI with the safety of enterprise design. One Flutter codebase renders native across mobile, web, and desktop.

Use cases

From static screen to adaptive surface.

Start with one high-intent surface in an app you already ship. Drop a generative zone into search, booking, or checkout, leave the rest of the app untouched, and measure the lift before you expand. Here is what that looks like across industries.

Travel & Hospitality

On-brand booking surfaces that adapt to traveler intent, preferences, and timing, without sacrificing design quality.

Retail

UI that replaces static filters and adapts in real time to shopper intent, surfacing the right products with less friction.

Financial Services

Long, multi-step tasks compressed into a single adaptive screen that keeps clarity, accuracy, and trust intact.

The vision

Your future product experience will be GenUI-Native.

Interfaces are moving from hand-built at compile time to generated at runtime, shaped around each user in the moment. There are two ways in. Add generative surfaces to the app you already ship, or build a product that is GenUI-first from the very first screen.

Retrofit

Add to your app via zones

Keep the app you already run. Drop personalized, on-brand generative surfaces into bounded zones inside it, with full control over navigation, fallbacks, and rollout. The fastest way to put GenUI in front of real users.

Greenfield

Greenfield GenUI-first experiences

Build a product where the interface is composed at runtime from the first screen, with only login and a few essentials hand-built. The deepest expression of GenUI, where the experience adapts to every user.

Not theory. Shipped.

GenUI Kit is built on work already running in production, so you start from proven patterns instead of a blank page. We have shipped generative UI for Google, including the financial services demo at Google Cloud Next and Dashy, and for large enterprises in travel, entertainment, and financial services whose work stays confidential. The lessons from those deployments are built into the kit you get.
