How to Prototype a Website Redesign Using an AI with Browser Access

Use a live website as context for a functional redesign prototype while preserving the product’s real content and flows.

How to Prototype a Website Redesign Using an AI with Browser Access

35:37 to 38:30: Yash points an AI with browser access at the live ChatPRD site and uses the rendered product as source material for a redesign prototype.

Before you start

What you need

  • A public or authenticated target URL
  • A specific redesign goal and audience
  • Pages, content, and behaviors that must remain

What you’ll make

A clickable redesign prototype that demonstrates the proposed information structure and key interaction.

Tools used

Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

5 steps

Step01

Define the Redesign Goal

Start by articulating the new vision for the website. For example, you might want to create 'persona-based learning journeys for different user types' such as Rev Ops, SDRs, and Marketing Ops.

Example prompt
State the current problem, target user, desired behavior, and pages that must remain recognizable.
Step02

Prompt AI with the Live URL

Use an AI tool with browser access, such as Perplexity Computer. Provide the URL of the website you want to redesign. The AI will use its browser access to analyze the live site's current structure and content as a starting point.

Example prompt
Open [live URL], inspect its content and navigation, then build a separate prototype rather than editing production.
Step03

Describe the New Structure and Functionality

Describe the new layout and features you envision. For example, explain that the homepage should feature different persona tracks and specify what should happen when a user clicks on one.

Example prompt
Restructure the experience around [new hierarchy and functions] while preserving [required content and actions].
Step04

Iterate on Specific Views

Refine the prototype through a back-and-forth conversation with the AI. Ask it to mock up specific pages or states. For example, request a 'logged-in view for a user, showing their progress and next suggested courses.'

Example prompt
Revise [specific view] to address [observed issue], keeping the rest of the prototype unchanged.
Step05

Use the Prototype to Communicate Vision

Use the generated functional prototype as a visual artifact to show designers and engineers the intended redesign. This interactive mock-up helps communicate the look and feel of the new user experience more effectively than a written description.

Example prompt
Package the clickable path and a concise current-versus-proposed comparison for stakeholder review.

What good looks like

  • The prototype uses real source content rather than invented placeholders
  • The named user path works across the relevant views
  • Stakeholders can compare the current and proposed behavior

Recover

If it goes sideways

The agent redesigns the wrong problem
Name the target audience, current friction, and success behavior.
The prototype invents content or features
Require it to cite the live page used for each section.
One view looks good but the flow breaks
Test navigation and state across the full named journey.
