ByEvery designer has experienced the same frustrating moment. You finish a layout, everything looks right, but something feels off. You zoom in. You zoom out. You compare it to a reference. The problem is still there but you cannot name it. After hours on the same screen, your eye stops catching errors.
The UI Design Analyzer was built to solve exactly this. Upload any UI screenshot and get a professional scored analysis across 7 design criteria in seconds. No login. No account. No payment. Free every time.
What the UI Design Analyzer Checks
The tool evaluates every uploaded design across 7 weighted criteria. Each criterion has a specific weight because not all design properties matter equally depending on context.
Spacing — 18% Weight
Checks padding, margin consistency, and breathing room between elements. Inconsistent spacing is the most common UI mistake and one of the hardest to self-diagnose after extended time on a design. The analyzer checks gap variance between elements and flags wherever spacing breaks the visual rhythm.
Alignment — 18% Weight
Detects misaligned elements, off-grid layouts, and inconsistent edge margins. Elements that are close to aligned but not precisely aligned register as visual noise to every viewer even when they cannot articulate why.
Color Usage — 15% Weight
Evaluates palette harmony, WCAG contrast ratios between dominant color pairs, and whether colors are over-used or under-used across the design. A failing contrast ratio is both a design quality issue and an accessibility compliance failure.
Consistency — 15% Weight
Measures whether corner radii, font sizes, and spacing values follow a consistent system throughout. Three slightly different border-radius values across similar components is the kind of inconsistency that makes a design feel unpolished without anyone being able to name the cause.
Hierarchy — 14% Weight
Assesses whether the design clearly guides the eye. Primary, secondary, and tertiary information should each have distinct visual weight. A flat hierarchy where everything competes at the same visual level is one of the most common issues in self-designed interfaces.
Typography — 12% Weight
Looks at font-size variety, line-height, and whether text scales are logical. A proper heading-to-body ratio creates the reading hierarchy. Insufficient size contrast between levels collapses the structure.
Corner Rounding — 8% Weight
Checks that border-radius values are consistent and appropriate for the design style. Mixing sharp and pill shapes across the same interface reads as unfinished. This is often overlooked because individual elements look fine in isolation.
Analysis Modes — Why They Matter
Different design types should be evaluated differently. A social media poster and a SaaS dashboard are not judged by the same standards. The UI Design Analyzer offers five analysis modes that adjust the scoring weights for context.
Web UI mode weights spacing and alignment most heavily because these properties most directly affect how a website reads and converts. Mobile mode shifts weight toward spacing and element separation, reflecting the higher stakes of touch targets on small screens. Poster mode weights color usage and visual hierarchy most heavily. Dashboard mode emphasizes alignment and consistency. Social mode focuses on attention and contrast at scroll speed.
Selecting the right mode before uploading takes two seconds and produces a meaningfully more relevant score for your specific use case.
The Score Grades
The overall score out of 100 maps to five letter grades. S-grade (90 and above) is publication ready. A-grade (80 to 89) is professional quality. B-grade (70 to 79) is good with minor improvements needed. C-grade (60 to 69) needs work. D and F grades (below 60) indicate foundational issues worth addressing before the design ships.
What the Feedback Actually Looks Like
This is where the tool does something different from a generic score. The feedback is element-level and specific. Not “your spacing could be better” — more like “hero body text is 11px gray on black, this fails WCAG readability, increase to 14px at #cccccc to ensure legibility across all screens.”
Each criterion shows its individual score and specific written feedback explaining the exact issue and the exact fix. Suggestions are sorted by impact so the highest-value fix always appears first.
Who Uses It
Freelance designers use it before client delivery as a final sanity check. Junior designers use it to build vocabulary for evaluating their own work. Developers use it to check interfaces they built without a dedicated designer. Small business owners use it to check websites and marketing materials they designed themselves in Canva or Wix.
The tool works equally well on websites, mobile app screens, posters, dashboards, social media graphics, packaging labels, and business cards.
How Images Are Handled
Your uploaded image is processed to generate the design feedback and is not stored long-term. A thumbnail is saved with your result if you choose to share it. No images are sold or shared with third parties. The analysis runs securely and the original file is not retained after the score is generated.
