Start from a prompt or template, preview the result using Syncfusion components, refine it through AI-assisted changes or direct JSON editing, and copy the resulting A2UI definition into your application. Composer handles the design-time experience, while Syncfusion A2UI Components handle runtime rendering across supported environments including React, Angular, Blazor, and .NET MAUI. AI applications often need more than text responses. A user might ask for last quarter’s sales by region, an inventory overview, a customer summary, or an appointment workflow. In these cases, the useful result may be an interactive grid, chart, form, scheduler, or combination of components rather than another block of text. Turning an interface idea into a working experience often takes several iterations. Developers need to decide which components to use, arrange the layout, review the result, and make changes before the interface is ready to use. [A2UI Composer](https://www.syncfusion.com/explore/a2ui-composer/) provides a visual way to simplify this process. Instead of starting with UI implementation, developers can describe the experience they want using a natural-language prompt or start from a ready-made template. Composer generates a structured A2UI definition that can be previewed, refined, and edited before it is used in an application. With support for Syncfusion components, developers can explore and shape AI-powered interfaces while working with familiar UI building blocks. Composer is the design-time part of the Syncfusion [A2UI](https://www.syncfusion.com/explore/a2ui/) workflow. It helps you define and refine the surface; the runtime renders that definition inside the application. ## Two halves of the same A2UI workflow Syncfusion separates interface authoring from application rendering. | | Design time | Runtime | | --- | --- | --- | | Tool | A2UI Composer | A2UI Components + renderer | | Purpose | Prompt or template → preview → refine → A2UI definition | Agent/backend emits A2UI messages → renderer maps them to Syncfusion UI | | Result | Reusable, inspectable interface definition | Interactive application UI | Composer is an optional authoring path. Teams can use it when they want to design and refine the expected interface structure first, then use that definition directly in the application or bind it to the agent workflow. ## What is A2UI? A2UI is a declarative approach for describing user interfaces as structured data instead of framework-specific UI code. A renderer interprets the definition and maps it to supported UI components. For example, an A2UI definition can describe a button, its content, and an interaction event without defining the complete framework-specific UI implementation. This separation is what allows Composer to stay focused on interface authoring rather than on one specific application framework. ## Meet Syncfusion A2UI Composer Syncfusion A2UI Composer is an AI-powered interface authoring environment that helps teams transform natural-language prompts into structured, reusable interface definitions. It is designed for prompt-to-UI and AI-assisted design workflows, helping developers move from an initial idea to an interface that can be previewed and refined. The resulting definition can then be taken into a supported application environment or used as the expected UI structure in an agent workflow ## How A2UI Composer works Composer brings together prompts, visual refinement, and structured interface definitions in one workflow. A typical Composer flow is: - **Describe:** Start by describing the interface you need or selecting a starter template.For example: ``` Create an inventory dashboard showing stock levels, low-inventory alerts, and warehouse performance metrics. ``` - **Preview:** See the generated interface rendered with Syncfusion components. - **Refine:** Adjust the layout, components, and data through AI-assisted changes or direct JSON editing. - **Copy:** Take the resulting A2UI definition into your application. **Describe → Preview → Refine → Copy** This provides a practical path from an interface idea to a structured definition without starting with a complete application implementation. ![Syncfusion A2UI Composer prompt-to-interface workflow](https://www.syncfusion.com/blogs/wp-content/uploads/2026/09/Syncfusion-A2UI-Composer-prompt-to-interface-workflow.png) A2UI Composer workflow ## Explore the A2UI Composer Experience Composer includes focused areas for generating, refining, exploring, and reviewing A2UI interfaces. - **Create:** Generate an interface from a natural-language prompt or a starter template. - **Workspace:** Refine the interface with AI, edit A2UI JSON directly, and review the live preview in the same authoring environment. - **Gallery:** Browse reusable starter experiences and open them in Composer. Starter examples include: - Operations Dashboard - CRM Overview - Finance Summary - Inventory Tracker - **Playground:** Experiment with individual components and structured definitions without creating a full interface. - **Catalog:** Explore the Syncfusion component adapters currently supported by A2UI ### Composer Workspace The Workspace provides the tools needed to refine an interface after its initial generation. **AI Assistant** Use natural-language instructions to request interface changes, such as layout updates, additional fields, styling adjustments, or supported changes to the interface. Composer applies the requested changes to the definition. **JSON Editor** For direct control, the JSON Editor provides access to the underlying A2UI definition. Developers can inspect and edit the generated structure while reviewing the result. **Live Preview** The Live Preview renders the interface as changes are made, allowing developers to review the result without switching between the definition and rendered experience. Together, these capabilities create a workflow for creating, reviewing, and refining A2UI interfaces. ![Building and refining an interface in the A2UI Composer Workspace](https://www.syncfusion.com/blogs/wp-content/uploads/2026/09/Building-and-refining-an-interface-in-the-A2UI-Composer-Workspace-2.png) Building and refining an interface in the A2UI Composer Workspace ## Build with supported Syncfusion Components A2UI Composer uses supported Syncfusion components as building blocks for generated interfaces. These include: - **Data and visualization:** Data Grid, Tree Grid, Charts, Maps, and HeatMap. - **Input:** TextBox, ComboBox, and Dropdown. - **Scheduling:** Scheduler, Calendar, and Gantt Chart. - **Navigation and layout:** Menu, Breadcrumb, Pager, Tabs, Cards, and placeholders. - **Documents:** PDF Viewer, DOCX Editor, and Spreadsheet Editor. Component availability is defined by the supported A2UI catalog. Do not assume that every Syncfusion component is currently available through A2UI; check the catalog when designing an interface around a specific control. ## From Composer to an application Composer focuses on creating and refining the interface definition. The resulting A2UI definition can then move into a supported application workflow. The process can be represented as: A2UI Composer ↓ Structured A2UI definition ↓ Application or agent workflow ↓ A2UI runtime and renderer ↓ Interactive Syncfusion UI At runtime, Syncfusion A2UI Components process the structured messages, map them to supported Syncfusion components, connect the required data, and handle user interactions. ## Use Composer definitions across supported platforms A2UI Composer itself is not tied to React. It produces the structured definition; the runtime platform determines how that definition is rendered. Syncfusion currently provides A2UI runtime integration for: | Platform | Package | | --- | --- | | React | @syncfusion/ej2-react-a2ui | | Angular | @syncfusion/ej2-angular-a2ui | | Blazor | Syncfusion.Blazor.A2UI | | .NET MAUI | Syncfusion.Maui.A2UI | Support for more platforms is planned. This means the same Composer workflow can feed supported runtime implementations without making Composer itself framework-specific. ## How the runtime uses the definition Once the A2UI definition reaches the application, the runtime takes over. Depending on the platform integration, it can: - Validate incoming A2UI messages before rendering. - Map definitions to supported Syncfusion components. - Connect structured data to interactive controls. - Process surface updates. - Route user actions back to the application or agent workflow. This keeps the interface definition separate from the application rendering layer. ## Platform integration is a separate step Composer stops at the structured definition. Integration into the application remains an engineering step. For example: - React applications install and configure the React A2UI runtime. - Angular applications use the Angular A2UI runtime and catalog. - Blazor applications register the A2UI services and renderer. - .NET MAUI applications use the corresponding MAUI A2UI package. This separation lets Composer remain platform-neutral while each supported runtime integrates with its own application environment. ## How A2UI Composer differs from traditional AI UI Builders Many AI-powered UI tools focus on generating application code from prompts. While this can accelerate prototyping, the generated code still needs to be reviewed, modified, tested, and maintained. A2UI Composer takes a different approach by generating structured interface definitions that can be rendered through supported A2UI runtimes. | Traditional AI UI generation | Syncfusion A2UI Composer | | --- | --- | | Generates application UI code | Generates structured A2UI definitions | | UI implementation is part of the generated output | Interface definition is separated from rendering | | Generated code requires review and maintenance | Definitions can be refined and reused | | Focuses on implementation generation | Focuses on interface composition | The key difference is the focus on structured interface composition rather than generating a new UI implementation for every request. ## Why this pattern matters? For application teams, the value is not only faster interface creation. - **Structured:** A2UI definitions make the interface explicit and inspectable, giving the agent and application a clearer interface contract. - **Reusable:** Supported components and interface patterns can be reused across multiple agent workflows. - **Consistent:** Agent-driven interfaces can use the same Syncfusion building blocks already used in the application. - **Governable:** The application controls the supported catalog and runtime instead of allowing an agent to generate arbitrary application markup. ## A practical A2UI experience Consider an inventory application. - Start with:``` Create an inventory dashboard showing stock levels, low-inventory alerts, and warehouse performance metrics. ``` - Composer generates an initial definition and preview. - You can then refine it with requests such as: - ``` Add a supplier filter. ``` or: ``` Move the low-stock items into a separate section. ``` - The Workspace updates the structured definition, and the Live Preview lets you review the result. - Once the definition is ready, copy it into a supported application workflow or use it as the UI structure expected from the agent. This demonstrates the role of Composer clearly: design and refine the experience before runtime integration. ![AI-generated flight search form in the SkyBook application](https://www.syncfusion.com/blogs/wp-content/uploads/2026/09/AI-generated-flight-search-form-in-the-SkyBook-application.png) AI-generated flight search form in the SkyBook application ![AI-generated flight results rendered in the SkyBook application](https://www.syncfusion.com/blogs/wp-content/uploads/2026/09/AI-generated-flight-results-rendered-in-the-SkyBook-application.png) AI-generated flight results rendered in the SkyBook application ![AI-generated flight booking confirmation in the SkyBook application](https://www.syncfusion.com/blogs/wp-content/uploads/2026/09/AI-generated-flight-booking-confirmation-in-the-SkyBook-application.png) AI-generated flight booking confirmation in the SkyBook application ## Where to start | If you want to… | Start with… | | --- | --- | | Create an interface from a prompt | Create | | Start from an existing example | Gallery | | Refine AI output and edit JSON | Workspace | | Test individual components | Playground | | Check supported components | Catalog | | Render the resulting definition | A2UI Components for your application platform | ## Conclusion Syncfusion [A2UI](https://www.syncfusion.com/explore/a2ui/) Composer provides a visual way to turn interface ideas into structured A2UI definitions.
