Building Legal Tech UIs from Video Walkthroughs

TL;DR: Replay enables rapid prototyping of legal tech UIs directly from video walkthroughs, drastically reducing development time and ensuring user-centric design.

The legal tech space is booming, but building intuitive and effective UIs remains a massive bottleneck. Traditional methods – wireframing, mockups, and iterative development – are slow, expensive, and often miss the mark when it comes to replicating real-world user workflows. What if you could capture the essence of a legal process simply by recording a video walkthrough and automatically translate it into a functional UI?

The problem with existing UI generation tools is simple: they're static. They treat screenshots as the source of truth. But a screenshot only shows what the user sees, not why they're clicking, typing, or navigating. This is where behavior-driven reconstruction comes in.

Replay changes the game.

The Problem: Static Screenshots vs. Dynamic Behavior#

Current screenshot-to-code solutions are inherently limited. They can generate a visual representation of a UI element, but they lack the understanding of user intent and the underlying logic driving the interaction. This results in brittle code that requires significant manual tweaking and often fails to accurately reflect the desired user experience.

Consider the process of filling out a legal document. A screenshot can show the fields, but it doesn't capture the order in which they are filled, the data validation rules applied, or the branching logic based on user input. Recreating this from static images is a nightmare.

The Solution: Behavior-Driven Reconstruction with Replay#

Replay leverages the power of Gemini to analyze video recordings of legal workflows and reconstruct functional UIs. Instead of just seeing pixels, Replay understands the user's actions – clicks, keystrokes, navigation patterns – and translates them into working code. This "Behavior-Driven Reconstruction" approach offers several key advantages:

• •Accuracy: Replay captures the nuances of user behavior, resulting in more accurate and intuitive UIs.
• •Speed: Generate functional prototypes in minutes, not days, by simply recording a video walkthrough.
• •User-Centricity: The UI is built directly from real-world user interactions, ensuring a user-centric design.
• •Maintainability: The generated code is well-structured and easy to maintain, thanks to Replay's intelligent analysis of the underlying logic.

Replay in Action: Building a Legal Intake Form#

Let's say you want to create a digital intake form for a law firm specializing in personal injury cases. Traditionally, this would involve:

1. •Creating wireframes.
2. •Designing mockups.
3. •Writing code for the UI and backend logic.
4. •Testing and iterating based on user feedback.

With Replay, you can skip steps 1-3. Simply record a video of a paralegal filling out a sample intake form, explaining their actions as they go. Replay will analyze the video and generate a functional UI, complete with form fields, validation rules, and data submission logic.

Step 1: Recording the Video#

Record a clear video walkthrough of the intake process. Speak clearly and explain each step as you perform it. This context helps Replay accurately interpret your actions.

Step 2: Uploading to Replay#

Upload the video to Replay. The engine will process the video and generate a working UI.

Step 3: Review and Refine#

Review the generated UI and make any necessary adjustments. Replay allows you to inject custom styles, integrate with your existing backend, and refine the user flow.

Here's a comparison of Replay against traditional methods and other UI generation tools:

Code Example: Handling Form Submission#

Replay automatically generates the necessary code to handle form submissions. Here's an example of a generated function that sends the form data to a Supabase database:

typescript
// Generated by Replay
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;

const supabase = createClient(supabaseUrl, supabaseKey);

const submitForm = async (data: any) => {
  const { error } = await supabase
    .from('intake_forms')
    .insert([
      data
    ]);

  if (error) {
    console.error("Error submitting form:", error);
    return false;
  } else {
    console.log("Form submitted successfully!");
    return true;
  }
};

export default submitForm;

💡 Pro Tip: Clearly narrate your actions in the video to provide Replay with valuable context. The more information you provide, the more accurate the generated UI will be.

Style Injection: Tailoring the UI to Your Brand#

Replay allows you to inject custom styles into the generated UI, ensuring that it aligns with your brand identity. You can use CSS, Tailwind CSS, or any other styling framework.

javascript
// Example: Injecting custom CSS
const customStyles = `
  .form-field {
    border: 1px solid #ccc;
    padding: 10px;
    margin-bottom: 10px;
  }

  .submit-button {
    background-color: #007bff;
    color: white;
    padding: 10px 20px;
    border: none;
    cursor: pointer;
  }
`;

// Inject the styles into the document
const styleSheet = document.createElement("style")
styleSheet.innerText = customStyles
document.head.appendChild(styleSheet)

⚠️ Warning: Ensure that your video recordings are of high quality and free from distractions. Poor video quality can negatively impact Replay's ability to accurately analyze the user's actions.

Product Flow Maps: Visualizing the User Journey#

Replay doesn't just generate individual pages; it understands the entire user flow. It can automatically generate product flow maps that visualize the user's journey through the application. This is invaluable for identifying potential bottlenecks and optimizing the user experience.

Why Video Matters: Understanding User Intent#

The key difference between Replay and other UI generation tools is its ability to analyze video. Video provides a rich source of information about user behavior that screenshots simply cannot capture.

📝 Note: Replay is constantly evolving, with new features and improvements being added regularly. Stay tuned for updates and announcements.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited functionality, as well as paid plans for more advanced features and usage. Check the Replay pricing page for details.

How is Replay different from v0.dev?#

While both tools aim to accelerate UI development, Replay focuses on behavior-driven reconstruction from video, while v0.dev relies on AI-generated code based on text prompts. Replay captures real user behavior, resulting in more accurate and user-centric UIs. v0.dev is great for ideation, but Replay excels at replicating existing workflows.

What types of legal tech UIs can Replay build?#

Replay can be used to build a wide variety of legal tech UIs, including:

• •Intake forms
• •Document assembly tools
• •Case management dashboards
• •Legal research interfaces
• •Client portals

What are the limitations of Replay?#

Replay relies on clear and well-structured video recordings. Complex or poorly documented workflows may require manual adjustments. Also, while Replay excels at front-end generation, significant backend logic may still require manual coding.
