TL;DR: Replay AI leverages video analysis to generate ARIA-compliant UI code, ensuring accessibility is built-in from the start, not bolted on as an afterthought.
Accessible UI is no longer a nice-to-have; it's a necessity. But building truly accessible interfaces can be time-consuming and require specialized expertise. What if you could automatically generate ARIA-compliant code directly from a screen recording of your intended user experience? That's where Replay AI comes in.
The Accessibility Bottleneck#
Many teams struggle with accessibility for several reasons:
- •Lack of expertise: Understanding ARIA attributes and accessibility best practices requires dedicated learning.
- •Retrofitting accessibility: Often, accessibility is considered after the UI is built, leading to costly and time-consuming fixes.
- •Maintaining accessibility: As the UI evolves, ensuring ongoing accessibility compliance can be challenging.
- •Testing complexities: Thorough accessibility testing requires specialized tools and knowledge.
Replay AI addresses these challenges head-on by baking accessibility into the code generation process. By analyzing user behavior within a video, Replay understands the intended use of each UI element, allowing it to intelligently apply ARIA attributes and ensure semantic correctness.
Replay: Behavior-Driven Accessibility#
Replay differs fundamentally from screenshot-to-code tools. We use video as the source of truth. This "Behavior-Driven Reconstruction" means Replay understands the intent behind user actions, not just the visual appearance of the UI. This is crucial for generating accessible code.
Consider a simple example: a custom dropdown menu. A screenshot-to-code tool might simply recognize the visual elements. Replay, however, analyzes the user interaction – the click to open the menu, the arrow key navigation, the selection of an item – and uses this understanding to generate the correct ARIA attributes (e.g.,
aria-haspopup="true"aria-expanded="true"aria-activedescendantExample: Reconstructing an Accessible Button#
Let's say you record yourself interacting with a custom button that toggles a settings panel. The video shows you clicking the button, the panel appearing, and then clicking the button again to close the panel.
Replay can generate code like this (simplified example):
typescript// React example with ARIA attributes import React, { useState } from 'react'; const ToggleButton = () => { const [isOpen, setIsOpen] = useState(false); const togglePanel = () => { setIsOpen(!isOpen); }; return ( <> <button aria-expanded={isOpen} aria-controls="settingsPanel" onClick={togglePanel} > {isOpen ? 'Close Settings' : 'Open Settings'} </button> <div id="settingsPanel" hidden={!isOpen}> {/* Settings panel content */} <p>Change your settings here.</p> </div> </> ); }; export default ToggleButton;

aria-expandedaria-controlsHow Replay Ensures ARIA Compliance#
Replay leverages several techniques to ensure ARIA compliance:
- •Behavior Analysis: As described, analyzing user interactions within the video is paramount.
- •Semantic HTML Inference: Replay strives to use semantically correct HTML elements (e.g., ,text
<button>,text<nav>) whenever possible, providing a solid foundation for accessibility.text<article> - •ARIA Attribute Prediction: Based on the inferred intent, Replay predicts and applies appropriate ARIA attributes. This includes roles, states, and properties to convey the meaning and purpose of UI elements to assistive technologies.
- •Configurable Accessibility Rules: Replay allows developers to configure accessibility rules and guidelines, ensuring adherence to specific standards and requirements.
- •Supabase Integration: Replay seamlessly integrates with Supabase for data management. This allows for dynamic content and personalized experiences while maintaining accessibility.
Step-by-Step: Generating Accessible Code with Replay#
Here's a simplified workflow for generating accessible UI code with Replay:
Step 1: Record the User Flow#
Record a video of yourself interacting with the desired UI. This video should clearly demonstrate the intended behavior and functionality. For example, show how a user would navigate a menu, interact with a form, or use a custom control.
Step 2: Upload to Replay#
Upload the video to the Replay platform. Replay will process the video and analyze the user interactions.
Step 3: Review and Refine#
Review the generated code and make any necessary adjustments. Replay provides a visual interface for inspecting the code and modifying ARIA attributes or semantic HTML.
Step 4: Integrate into Your Project#
Copy the generated code and integrate it into your project. Replay supports various frameworks and libraries, including React, Vue.js, and Angular.
Step 5: Test and Validate#
Test the integrated UI with assistive technologies, such as screen readers, to ensure accessibility compliance. Use accessibility testing tools to identify and address any remaining issues.
