Frequently Asked Questions

LogoAnalyzer.com is a scientific logo analysis platform that combines real computer vision measurements with cognitive neuroscience research. First, our system computes objective metrics via computer vision: color extraction with WCAG contrast ratios, bilateral symmetry, Shannon entropy complexity, edge density, and golden ratio analysis. In parallel, we run colorblind simulation (protanopia, deuteranopia, tritanopia, achromatopsia), image quality assessment (NIQE, BRISQUE, MUSIQ), color harmony analysis, and CLIP zero-shot semantic classification. These measured data points then feed into AI interpretation grounded in published neuroscience and psychology research — brainwave simulation, neurotransmitter predictions, eye tracking, and emotional mapping. The measurements are real; the interpretation is science-based.

Most tools give you AI-generated scores with no underlying measurements. We start differently: real computer vision measures your logo's actual symmetry, complexity, color contrast ratios, and proportions. We also run colorblind accessibility simulation, no-reference image quality assessment, mathematical color harmony scoring, and CLIP zero-shot classification for industry and style detection. These objective data points then feed into neuroscience-informed AI that produces brain region activation maps, neurotransmitter predictions, eye tracking simulations, and emotional response profiles. Every score is anchored in measurable visual properties — not AI guessing what 'looks nice.'

Upload your logo and optionally specify your industry and brand context. Your logo enters a multi-layer pipeline: Layer 1 runs real computer vision measurements — color palette extraction, WCAG contrast ratios, symmetry analysis, Shannon entropy complexity, edge density, golden ratio proximity. In parallel, Layer 2 runs objective third-party tools — colorblind simulation under 4 vision conditions, no-reference image quality assessment (NIQE, BRISQUE, MUSIQ), CLIP zero-shot semantic classification, and after colors are extracted, mathematical color harmony analysis. Layer 3 feeds all measured data into AI interpretation informed by cognitive neuroscience, Gestalt psychology, color science, and cross-cultural semiotics. The result is 150+ metrics across 14 scientific dimensions.

Personas are not generic profiles — they are scientifically constructed audience simulations grounded in demographic and psychographic research. Each persona represents a distinct viewer type with specific age, gender, lifestyle, economic background, and digital behavior patterns. Every persona independently evaluates your logo and produces its own data: emotional arousal intensity and valence, happiness/anxiety/neutrality breakdown, attention capture and retention scores, simulated heart rate and skin conductance changes, brand familiarity ratings, and sentiment analysis. This reveals how a 25-year-old tech professional responds differently to your logo than a 55-year-old corporate executive — with measurable, comparable data for each.

Each analysis produces 150+ individually scored metrics across 14 scientific dimensions: Design Quality & Composition, Psychology & Emotion, Neuroscience & Brain Response, Eye Tracking & Visual Attention, Cognition & Memory, Trust & Market Positioning, Color Science, Typography, Cultural & Global Readiness, Design Attributes & Versatility, Colorblind Accessibility (protanopia/deuteranopia/tritanopia/achromatopsia simulation with effectiveness scores and problematic color pairs), Image Quality Assessment (NIQE, BRISQUE, MUSIQ composite scoring), Color Harmony Analysis (harmony type detection, color wheel distribution, CSS4 naming, improvement suggestions), and CLIP Semantic Classification (industry classification, design attribute scores, brand archetype confidence, style tag detection).

When your logo demonstrates strong neural performance across our scientific dimensions — high memory encoding strength, positive emotional valence, effective attention capture, strong trust signals, and balanced cognitive load — it earns a LogoAnalyzer certification. This is a verifiable certificate with a unique QR code, a tier-based grade reflecting overall neuroscience performance, an embeddable badge, and a shareable verification link. It signals to clients and stakeholders that your logo has been scientifically validated for cognitive impact and brand effectiveness. Enterprise users receive white-label certificates with custom branding.

Yes. Our Logo Comparison tool runs the full neuroscience analysis pipeline on 2 or 3 logos simultaneously, then produces a side-by-side metric-level comparison. You can see exactly how each logo performs across brain activation patterns, emotional response profiles, attention capture efficiency, memory encoding strength, and market positioning scores. This is ideal for A/B testing redesigns, benchmarking against competitors, or evaluating multiple concepts — with scientific data rather than subjective preference.

Sign up for free — no credit card required. You get 1 free analysis with 1 persona. Upload your logo on the home page, optionally add your industry and brand description for deeper contextual analysis, and click 'Start Analysis'. Within moments, you'll receive a full neuroscience report with brain activation maps, emotional response data, eye tracking predictions, and scored metrics across all 10 scientific dimensions.

We accept PNG, JPG, GIF, and WebP formats. SVG files are not currently supported as our AI vision models require rasterized images. For the most accurate analysis — especially for color science, contrast ratios, and fine geometric structure evaluation — we recommend uploading a high-resolution PNG or JPG on a clean background. Our visual decomposition engine extracts color palettes, typography, geometric structures, and spatial relationships regardless of format, but higher quality input produces more precise neural response predictions.

Selecting your industry activates competitive benchmarking against established brands in your sector. Your logo's neural performance scores — trust signals, purchase intent, premium perception, differentiation index — are evaluated relative to industry standards and top competitors. We support 100+ categories from Technology & SaaS to Healthcare, Finance, Retail, and more. This contextualizes your results: a high-energy, vibrant logo might score well for a sports brand but poorly for a financial institution. Industry context makes the science actionable.

Filters let you configure the scientific audience simulation by specifying target demographics: age group, gender, economic status, education level, lifestyle, and digital habits. This directly shapes which personas are generated and how they evaluate your logo. A logo targeting Gen Z digital natives will receive fundamentally different neural response profiles than one targeting affluent retirees — different emotional triggers, attention patterns, trust signals, and cultural associations. Filters ensure the neuroscience data matches your actual market.

Yes. Every new user gets 1 free analysis with 1 persona — no credit card required. You'll receive the full neuroscience pipeline output: brain activation maps, emotional response scores, eye tracking predictions, and all 150+ metrics.

Our pipeline has three foundations: objective measurements, validated third-party tools, and published research. Layer 1 computes real metrics via computer vision — symmetry, complexity (Shannon entropy), edge density, WCAG contrast ratios, golden ratio proximity, and color science. Layer 2 runs objective third-party tools: colorblind simulation (Brettel/Viénot matrices), no-reference image quality assessment (NIQE, BRISQUE, MUSIQ from PyIQA), mathematical color harmony analysis, and CLIP zero-shot semantic classification (OpenAI). These measurements are then interpreted through published research across: EEG and fMRI visual perception studies, cognitive psychology, chromatic emotion mapping, Gestalt psychology, behavioral economics, and cross-cultural semiotics. The key difference: our AI interprets measured data — it doesn't generate scores from nothing.

We simulate how your logo activates specific brain structures based on neuroscience research: the prefrontal cortex (executive decision-making and brand evaluation), the amygdala (threat/reward assessment and emotional processing), the nucleus accumbens (pleasure and reward response — critical for brand desire), the fusiform face area (pattern recognition and visual identification), and the visual cortex (initial image processing and feature extraction). We also predict brainwave activity across all five frequency bands — Delta (deep processing), Theta (memory encoding), Alpha (relaxed attention), Beta (active engagement), and Gamma (higher-order cognition) — and map a temporal response timeline showing the millisecond-by-millisecond sequence from initial visual capture through emotional response to meaning attribution.

Our predictive eye tracking system is calibrated against real-world gaze studies to simulate how viewers visually navigate your logo. It produces: animated gaze path sequences showing the order in which elements capture attention, fixation duration measurements per design element, saliency scores ranking each element by attention-capturing ability, attention heatmaps visualizing where visual focus concentrates, visual flow efficiency measuring whether your hierarchy guides the eye intentionally, and attention retention rates predicting how long viewers stay engaged. This reveals whether your logo's most important elements actually receive the most attention — or whether secondary details steal focus from your core brand message.

Based on visual perception research linking design characteristics to autonomic nervous system responses, we predict how your logo influences four key neurotransmitters: Dopamine (reward, motivation, desire — does your logo trigger wanting?), Serotonin (trust, well-being, stability — does your logo feel reliable?), Cortisol (stress, alertness, urgency — does your logo create tension?), and Adrenaline (excitement, energy, arousal — does your logo energize?). The balance of these predictions reveals whether your logo neurochemically aligns with your brand intent. A luxury brand should trigger dopamine and serotonin, not cortisol. An energy drink should trigger adrenaline and dopamine, not pure serotonin.

Our approach has multiple accuracy levels. Layer 1 (computer vision) produces objectively verifiable measurements — color values, contrast ratios, symmetry percentages, complexity scores. Layer 2 (third-party tools) adds more objective data: colorblind simulation uses published Brettel/Viénot matrices, image quality scores come from established academic models (NIQE, BRISQUE, MUSIQ), color harmony uses mathematical angle analysis, and CLIP classification uses OpenAI's pre-trained visual-language model. Layer 3 (AI interpretation) uses all these measurements as ground truth inputs, then interprets them through neuroscience research. This multi-layer anchoring in measured data makes AI predictions significantly more accurate than systems that generate all scores from scratch.

Your results are delivered through a multi-tab interactive dashboard: Overview (overall neural score, key metrics, first impression data), Persona Evaluations (per-persona emotional arousal, valence, sentiment, physiological responses), Brain & Neuroscience (brain region activation maps, brainwave band visualization, neurotransmitter predictions), Eye Tracking (animated gaze paths, attention heatmaps, fixation durations, saliency scores), Color & Design (palette extraction, color harmony wheel, colorblind accessibility previews, color psychology mapping, Gestalt compliance, golden ratio analysis), General (image quality assessment gauges, CLIP semantic classification with industry/archetype/style analysis), and Market & Competitive (trust scores, purchase intent, differentiation index, industry benchmarking).

The 25+ page PDF report contains the complete scientific analysis: all 150+ scored metrics with explanations, brain region activation maps and brainwave visualizations, eye tracking heatmaps and gaze path data, per-persona emotional and physiological response profiles, color science analysis with accessibility scores, typography psychology insights, market positioning benchmarks, and actionable recommendations grounded in the neuroscience data. It's designed for presentations, client deliverables, and strategic documentation.

Color analysis starts with real computer vision measurements: we extract your exact dominant colors with hex/RGB/HSL values and percentages, compute WCAG 2.1 contrast ratios against backgrounds (checking AA and AAA compliance for both normal and large text), measure color temperature (warm/cool), and calculate saturation and lightness statistics. We then run mathematical color harmony analysis — detecting whether your palette is complementary, analogous, triadic, split-complementary, tetradic, or monochromatic — with a harmony score and suggested improvements. Each color is identified by its CSS4 name and positioned on an interactive color wheel. Additionally, colorblind simulation renders your logo under protanopia, deuteranopia, tritanopia, and achromatopsia to verify accessibility. These measured values then inform AI interpretation through color psychology research.

When you select an industry, our system benchmarks your logo against the visual patterns and neural performance characteristics of established brands in your sector. The comparison evaluates visual differentiation (how distinct is your logo in the competitive landscape), cognitive distinctiveness (will viewers remember your logo among competitors), trust signal alignment (does your logo match or exceed industry trust standards), and market positioning scores (purchase intent, premium perception, loyalty potential relative to sector norms). This turns abstract competitive feelings into measurable scientific data.

Yes. You can purchase additional personas per analysis to broaden your demographic neural profiling. Each added persona independently runs through the full neuroscience evaluation pipeline and produces its own emotional, cognitive, and physiological response data. The cost varies by plan: $1.29 for Unlock, $0.99 for Starter and 5-Pack, $0.79 for 10-Pack, $0.59 for Professional. Enterprise plans include unlimited personas.

We use industry-standard security measures including 256-bit SSL encryption for all data in transit, secure cloud storage for uploaded files, and strict access controls. We are GDPR compliant and never share your data with third parties without your consent.

Your logo is stored securely on our servers so you can access your analysis results at any time. We never use your logos for AI training purposes or share them publicly. Your visual assets and neuroscience data remain exclusively yours. If you want your data deleted, contact our support team and we'll remove everything from our systems.

Yes. Your analysis results — including all brain activation data, emotional response profiles, eye tracking predictions, and scored metrics — are private by default and only accessible to your account. The only way others can see your results is if you explicitly create a share link with your chosen privacy settings (available on paid plans).

Visit our Contact page for assistance. Our support team — familiar with the neuroscience methodology behind every metric — typically responds within 24 hours. Professional and Enterprise subscribers receive priority support with faster response times.

Our multi-stage scientific pipeline — visual decomposition, neuroscience modeling, persona simulation, eye tracking prediction — typically completes within 1-2 minutes. If your results page shows 'processing' for more than 5 minutes, try refreshing the page. If the issue persists, contact our support team with your analysis ID and we'll investigate immediately.

Each analysis uses one credit from your plan. To evaluate the same logo with different audience filters or persona configurations, you would submit a new analysis. Different demographic targets produce fundamentally different neural response profiles — a logo that scores high with young urban professionals may score differently with rural retirees — so re-running with different settings provides genuinely new scientific data.

Enterprise plan users have access to a dedicated account manager who can help interpret neuroscience results and translate them into brand strategy decisions. For other plans, our support team is available to help you understand your brain activation maps, persona response data, and how to act on the 150+ metrics in your report.
