The Problem
You describe a design to an AI tool: "Make it look like Stripe." The result? Wrong colours, wrong fonts, wrong spacing. Vague prompts produce vague results.
"Make a card with a modern look, similar to Stripe"
The PromptLens Fix
Upload a screenshot. PromptLens extracts the exact design tokens — hex colours, font sizes, border radii, shadow values — and generates a prompt your AI tool can actually use.
"White card (#FFFFFF), 8px radius, shadow 0 4px 6px rgba(0,0,0,0.1), Inter 16px medium, 24px padding, bg #F6F9FC"
How It Works
Three steps. Under 30 seconds. No design skills required.
AI Extracts Style DNA
Claude Vision analyses your design and extracts the colour palette, typography, spacing, borders, shadows, and layout patterns — all with exact CSS values.

Frequently Asked Questions
What is PromptLens and who is it for?
PromptLens is a visual prompt engineering tool for designers, developers, and anyone using AI design tools. Upload a design screenshot — from Figma, a website, or even a whiteboard photo — and PromptLens uses AI to extract the exact styles and generate a prompt you can paste into tools like Google Stitch, Cursor, or Anima.
How does the AI design analysis work?
PromptLens uses Claude Vision AI to analyse your screenshots pixel by pixel. It identifies colour palettes (with hex codes), typography (font families, sizes, weights), spacing values, border styles, shadow definitions, and layout patterns like flexbox or grid structures. The analysis typically takes 10-15 seconds.
What AI design tools does PromptLens work with?
PromptLens generates optimised prompts for Google Stitch, Cursor AI, Anima, and a generic format that works with any AI coding or design tool. Each export format is tailored to the tool's specific syntax and preferences for the best results.
What image formats and sizes are supported?
PNG, JPEG, and WEBP images up to 10MB each. You can upload up to 3 screenshots per prompt. Higher resolution images produce more accurate style extraction.
Is PromptLens free?
Yes — the free plan gives you 3 AI design prompts per month with all export formats included. No credit card required. The Pro plan at £7/month unlocks unlimited prompts and priority analysis. Cancel anytime.
Is my design data secure?
