🎨 Stop Guessing, Start Designing: The Ultimate AI UI/UX Design Critic Prompt

By: 2numara3535@gmail.com

Ever feel like you're designing in a vacuum? Whether you are a solo developer trying to make your app look professional, or a UI designer looking for a fresh pair of eyes (that won't judge you too harshly), getting objective feedback is tough. You usually have to pester friends or hire expensive consultants.

Not anymore. Today's prompt transforms ChatGPT into a comprehensive UI/UX Design Analyst. But it doesn't just stop at "make it pop." It forces the AI to wear three different hats—Designer, Engineer, and User—to give you a 360-degree review of your interface. Let's dive in!

The Prompt

Copy and paste the following prompt into ChatGPT. Make sure to attach a screenshot of the app interface you want analyzed!

Act as a UI/UX Design Analyst. You are an expert in evaluating mobile application interfaces with a focus on maximizing visual appeal and usability. Your task is to analyze the provided mobile app screenshot and offer constructive feedback from multiple perspectives:\n\n- Designer: Analyze the visual elements and suggest design improvements.\n- Engineer: Evaluate the technical feasibility of design choices.\n- User: Provide insights from a user experience perspective, identifying potential usability issues.\n\nYou will:\n- Identify design inconsistencies and suggest enhancements.\n- Assess alignment with UI/UX best practices.\n- Provide actionable recommendations for improvement.\n\nRules:\n- Focus on clarity, intuitiveness, and visual harmony.\n- Consider accessibility standards.\n- Be objective and constructive in your feedback.\n\nUse variables:\n${context} - Additional context or specific areas to focus on.Application ScenariosThis prompt is incredibly versatile. Here is where it shines the brightest:1. The Solo Developer's Audit: When you are coding the backend and frontend, design often takes a backseat. Use this prompt to perform a quick "sanity check" on your UI before you commit the code.2. Pre-Launch Polish: Before submitting to the App Store or Play Store, run your key screens (Home, Checkout, Settings) through this prompt to catch accessibility issues or confusing navigation paths.3. Competitive Analysis: Upload a screenshot of a competitor's app. Ask the AI to analyze it to uncover what they are doing right—and where their UX fails—so you can capitalize on their weaknesses.Prompt AnalysisWhy does this prompt generate such high-quality responses? It comes down to Perspective Triangulation.Most generic prompts like "Critique this design" result in vague fluff like "It looks nice." This prompt forces the model to simulate specific expert personas:The Designer Persona: Focuses on aesthetics, hierarchy, and consistency (e.g., "The padding on this button is inconsistent with the header").The Engineer Persona: Grounds the feedback in reality (e.g., "This blur effect might cause performance drops on older Android devices").The User Persona: Simulates the friction of actual use (e.g., "My thumb can't reach the back button easily").By explicitly asking for these three distinct viewpoints, you get a balanced, actionable report rather than just an opinion.Usage ExamplesHere is how you might interact with this prompt in a real scenario:User Input:
(Uploads a screenshot of a dark-mode fitness tracking dashboard)
${context} = "This is the main dashboard for a running app. I am worried the text might be too small for users running outdoors."ChatGPT Response (Simulated):1. Designer Perspective:
The dark mode color palette is sleek, but the contrast ratio on your secondary text (#555555 on black) is failing accessibility standards. For outdoor use, you need higher contrast. I recommend lightening the gray to at least #AAAAAA.2. Engineer Perspective:
The real-time graph visualization looks complex. Ensure you are using a lightweight library like D3.js or native canvas rendering to prevent battery drain during long runs.3. User Perspective:
The "Start Run" button is located at the top right. If I am holding my phone with one hand while stretching, I cannot reach it. Move this primary action to the bottom center for better thumb reachability." }
