5 steps
Clearly identify the UI you want to build or redesign, such as a homepage, dashboard, or a specific tool. The model performs best with B2B SaaS applications and developer-focused tools.
Write a prompt that describes the desired outcome. Include context about the purpose of the tool, key sections to include (e.g., hero, value props, customer logos), and the overall goal, such as improving conversion.
Submit your prompt to Claude Opus 5.5. It will generate the complete HTML, CSS, and JavaScript code for the functional prototype.
Analyze the generated prototype for visual appeal, functionality, and overall structure. Note how it incorporates visual hierarchy, interactive elements, and information architecture to achieve your goal.
Copy the generated code into your development environment. Manually correct any minor visual imperfections, such as alignment issues or unwanted borders, to finalize the prototype for use or further development.
Turn an idea into a PRD, user stories, and a plan.
